Warmer Than Usual - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

Hello,
I just bought the SGT Pro 8.4 on Tuesday and today morning I turned it on and it was at 30% and let charging from 10 AM to 3:30 PM. When I started using it just now, 4 PM, I found that the bottom s side where the power button is, had been a littoral host then usual. Even the left side of the tablet and a part of the back. Is this normal?
PS - it was on the entire time.
Edit: After unplugging and keeping it idle for fifteen minutes, the temperature read 36*C./38*C Should I be worried?
Thanks,
Crazysah

I'm charging my tablet now and it is up to 49*C. Should I be worried?

Samsung Galaxy Tab Pro 10.1 - Warm
Good Day,
I was wondering about the average heat expected on the 10.1 as well. I notice that it gets warm just to the the right of the Samsung Logo, in a 2x4 inch area close to the bezel. I assume this is where the Exynos 5 Octa processor resides, correct me if I am wrong. You can feel the warmth on the screen and through the back, even in a case under normal/idle conditions.
I hope this is normal, possibly due to the TouchWiz UI, the CPU clock and/or high resolution of the screen. Can anyone else comment on this? It does seem to go away when the screen is off but stays warm even on the lowest brightness and using Kindle or reading PDFs. Thanks for any information you can provide.

Samsung Galaxy Tab Pro 10.1 - Warm
I have reset the tablet to default and installed only a few select apps, disabled the GPS and Bluetooth, etc. The temperature is just under body temperature.
However, when I place the SD card in it's slot and power on the tablet it seem that the tablet gets noticeably warmer. The card is a 32GB Sandisk UHS 1. It was used in an Asus MemoPad FHD before this. I then reformatted the card and placed back in the tablet, but the tablet still gets significantly warmer than if there were no card at all. The tablet does not overheat by the way, at least not yet, but it does seem to be doing more work while the SD card is installed.

Interesting as I was using a wireless QI charger on a Nexus 5 and it would stop charging with an overheat warning at 48*C.

Alright, it seems that the reason for the difference in temperature with and without the SD card might be due to the content on the card. I have a lot of PDFs, some very large and some with poor names. Android's indexing service is seen to be using 35% of the battery which would translate to the CPU being utilized heavily by this app. The CPU was between 50-60%. It even uses up more power than the screen.
I removed the large files and then cleaned up all the file names. I moved the files to the onboard storage and formatted the SD card. The indexing service is still running, but I believe this would take some time until it finishes. I will try to move the files, one at a time, back to the external SD card once this gets under control. The CPU is now around 42-45% and the temperature at 38C. Hopefully this should sort itself out soon.

Now that you had the A100 for a while any problems

Now that I have had this tab for a month. Its now starting to act up. Browser force closing, touch screen can be difficult to navigate (too sensitive) it will often open apps when swiping through screens, and overall performance is getting really slow. I have added a memory card to free up some memory but doesn't help. So I'm wondering what the community experience for us that has had the device for awhile.
Sent from my A100 using xda premium
I really like my A100 overall. Three things that are starting to kill me about it are:
1: Battery life; I've attempted to remove all/some/certain apps, turn off syncing, set sync long, turn wifi/gps off, remove "bloat", turn screen brightness low etc.. For the last two weeks I've tried a lot of different methods to save battery. Still, last night I went to sleep with it at 60-70%(on my latest method to save battery) and woke up with it completely drained. Might need to exchange it I guess.
2: Viewing angles. Thought I could deal with it no problem. However, when I use it as an e-reader (or anytime is portrait) the viewing angles make it difficult to look at the screen for extended periods of time. I have to tilt the left side back more so I don't strain my eyes.
3: Live wallpapers; Many are unusable. I have 4 widgets total and only use 3 home screens. On many of the live wallpapers I use, the swiping of screens either is very laggy, or has a very obvious delay in the time I swipe to the time the screen actually moves.
Performance has started to get slightly worse, not too bad though. I have started to get force closes on some apps and the browser. May end up returning / selling this and get something else. Pity, I really like it other than the first two annoyances..I can live without live wallpaper.
Battery life is a sore point for me as I'm sure it is for everyone. The screen isn't great, but it's not bad enough to bother me much.
I haven't had any software problems fortunately, or at least not any that aren't common with the whole Honeycomb live beta that Google has been running all year. Hopefully ICS will fix a lot on the software side.
That being said, I'm coming from a Nook Color(with a Kindle Fire also considered). Since I paid in the same price range for this($189 on Black Friday) the trade offs as compared to the Nook/KF aren't too bad and at the end of the day I do like having a full tablet with out having to turn it into an ugly hack job(I'm especially looking at you Nook Color)
For $200, I'd say I got my moneys worth, and I might even say it's worth it for the $260 BestBuy is still selling them for, but anything higher, and I'd say it'd be too much to pay for this thing. It's not a high quality tablet, the screen and battery life seal the deal on that one, but it's definitely not the worst tablet I've seen out there. It's miles better than all the cheap Chinese crap tablets, but it doesn't to much to exceed the standards of the "upper crap" brands like Archos.
I'd say the thing is worth about $250.
For now, I think 7" is the sweet spot for tablets. (I previously owned a 10.1" Asus Transformer, which had great battery life and a beautiful screen but was awkwardly big/heavy).
And that said, the A100 is the best 7" tablet currently available (including the new 7" Galaxy Tab, simply because it lacks a microSD slot. I wouldn't trade my microSD slot for 3 more hours of battery life and an IPS screen, especially if the deal added $100+ bucks to the price.)
- I give the screen a B+ (I do wish it didn't solarize from the bottom viewing angle, but it's otherwise bright and clear.)
- Real world battery life, C+ (6 hours is fine enough in practice because I charge nightly, but it'd be awesome to have 12 hours--save me from bringing the charger on short trips, etc.)
- The industrial design I don't care at all about. I have it in the phenomenal Blurex leather case, so the lame blue plastic/silver swirl thing on the back is a non-issue to me.
Really, Acer made all the right compromises. My next tablet will probably be the Transformer 3 when it comes out in a year, hopefully it'll have 300 ppi screen and will dual boot Jelly Bean and Windows 8. If Windows developers embrace ARM , I think a Transformer 3 + laptop dock will mean I'll never buy another PC.
Until tablets can replace laptops (early 2013), a cheap but fullspeed 7" is a great device.
I've had mine for about 2 weeks and I have seen some slowdown when booting up and scrolling in the app drawer from time to time but most likely due to having installed so many apps. Battery has been better for me. I have my wifi to turn off when screen is off and also have a wifi toggle widget to turn off wifi when I'm playing a game or sometimes I just turn off wifi completely when I'm not using the tablet which only drains my battery about 1-2% per hour. Overall usage I would say I get the normal 5 hour mark. Viewing angle is not much an issue for me as I always look at the tablet straight on and its much sharper than my older Samsung tab 7. The only issue I still have is the screen not being responsive or some are saying too sensitive. There's a thread on this already. I'm hoping this will be fixed via software. This is my 3rd one however since my other 2 had wifi issues. I fixed one but it still had screen touch issue so I exchanged and all 3 was the same. So far I'm happy for the $248 I purchased it for. I bring this thing everywhere i go since it fits inside my jacket pocket.
Mainly battery life is the sore point for me.
The screen is more sensitive than my iDevices but nowhere as bad as my LG Evo phone was. A bit more sensitive than the Blackberry Playbook.
Disabling the capacitive home button was a must for me. I would hit it so many times when holding it in landscape view, it drove me crazy.
The screen, I agree with everyone else about the viewing angle from the bottom not being good.
Of course, there is always room for improvement. The hardware in the PB is great, especially the screen and battery life but the software is way lacking in comparison to Android.
At $250, it is a good tablet. I wouldn't pay more for it than that.
It's the perfect size and I take it almost everywhere.

I bought one.for my daughter and have been playing with it for 2 weeks now..Rooted it as soon as.I took it out of the box and installed a few root apps like ad free to keep her from clicking on ads.
For $250 I have to say I am pretty impressed. I have loaded it up with a bunch of educational apps as well as games. So far I have not had one force close on any app. Battery life is ok and WiFi is fastest device off same router as my dinc and t60.
I am not sure what you guys expect for 250, but if you can find any Android device that doesn't need.to be charged daily, then you aren't using it.
Just my opinion

My thoughts exactly for the price it cant be beat. Very happy with the purchase. here is a screen cap of my a100 i never turn off wifi, this was with light usage. with regular use gaming/browsing for me I still get 8hrs.
For personal use the A100 is the perfect tablet, it easily fits in the inside pocket of a jacket, and despite complaints from others that the screen and battery life is not ideal, I think the screen is adequate and after 7 weeks I once had an empty battery. It is complete with Android 3.2, HDMI (works great as HTPC), 3.5mm audio connector, GPS, dual camera (not its strongest point), micro USB slave (missing USB host), Micro SD slot, and replacable battery. Upgrade to ICS is available next month. Moreover, it is much more affordable as similar products from its competitors.
Has anyone tried to use the tablet with it lying on any surface. Recently i discovered that with it on a bed or table lying flat the touch screen is practically unusable. Using a stylus for note taking is useless, it doesn't register every stroke and writing is broken up.

Yeah the touchscreen has some issues. If you lightly swipe the touchscreen on the browser it will zoom in I dunno why
@qhinton:
If you must use the A100 while it's lying on a table or a bed, try turning it upside-down first. There is no backlight on the bottom edge, only on the top edge. Viewing from above the top edge, or flipping the A100 upside down and viewing from below, is much better that way. Not perfect, but better.
Another remedy is to get an easel case, so you can prop the A100 at a comfortable viewing angle.

Thanks I found that trick out from using a Viewsonic GTab. What I was explaining is that the tablet needs to be grounded to work properly. So basically if your not holding it the tablet struggles with registering your gestures. Whem laying it on a bed or table the tablet touch screen would be very sporadic.

If you have major sensitivity issues try my fix posted here:
http://forum.xda-developers.com/showthread.php?t=1347123&page=6
This has mostly fixed the issue for me, still shows up every once in a while but after doing this fix there was a huge improvement for me.
WiFi keeps turning itself off every few minutes. checked all the settings and it still does it. none of my other Android devices do this, only the Tab 7"
after two months of use.
I'm very satisfied of this tab. No "problem" at all.
Battery life: is good if used well. Obviously could be better, but with a double core and a so large display is very good. It surprises me when i play HD games for long and i see almost no change in battery life.
Wifi: signal reception is good, no problem. Connection speed at my home is almost 1Mb/sec checked on tablet.
Display and touch: angle of sight is small for a tablet, but colors and luminosity is very good. Touch screen is very very sensible but i like it. With the screen saver the touch is perfect.
Performance: I'm agree with my colleagues about the live wallpaper. Sometimes they are too slow. The computing speed of this tab is very very good. Opening apps, photos and hd video is vey fast. It's definitely a fast tab
Camera: Is good enough. I've recently bought a Galaxy S 2 with a 8mp camera and I see the difference from the 5mpx of the A100 but is still capable of very high detailed photos.
Voip and VideoCalls: I use this two features a lot since I'm often away from home and both are very good. No lag at all. Video is clear and fluid, audio too. The microphone volume is low I think, but is not a problem if you can hold it closer to you.
Handling and Style: I can bring it inside a pocket and go wherever I want. Is not heavy, it doesn't need a separate bag to be kept with you. Is the perfect size in terms of mobility. The shape is cool and can be handled easily. Maybe the back of the cover would be better completely gray or black.
No problem apart from the fact that i cannot delete bloat cuz i dunno which system app will brick if i delete em, weight since i hold it in portrait mode often, FCs, lastly screen ratio. Prefer it wider and shorter.

If you mess up you should be able to just flash any of the update.zip in the rom thread to bring those files back. You will need to reroot if were already rooted.

Can dropping a phone make it slower?

Today...the unthinkable happened.
I dropped my phone from about 3 feet!
Luckily, I had a case on it, and there wasn't any damage to it...cosmetically. When I went to make sure there wasn't any internal damage, I tried a SetCPU stress test, a quadrant benchmark, an antutu benchmark, and a Linpack benchmark.
SetCPU was stable, quadrant was higher than before, and linpack was about the same. However, when I got to Antutu, my score was about 1000 less than before.
Before, I got RAM=~950, CPU Integer=~1825, and CPU Float=~1427. However, now I get RAM = ~700, CPU Integer = ~1350, and Cpu Float = ~1150. Everything else was about the same.
I should also note that at the time of testing, the phone was pretty hot (100 degrees Fahrenheit). The original scores were achieved on 80-90 degrees. Would you say this is a coincidence (and it was caused by heat), or hardware damage?
Coincidence.
Sent from my Galaxy Nexus using xda premium
I can run quadrant twice, doing nothing between tests but push the start test button, and get two completely different scores.
It was the heat after all. I let it cool down to 80 degrees fahrenheit, and it's back to the normal 6000+ scores. I feel so relieved now.
Did you pick up all the binary bits from the floor? Maybe some bits fell out so phone is still busy looking for the missing bits.

My HTC One M8 fell by 2 feet. On the corner; has hard shell.
After this, the phone was very slow. The kind of slowliness I do not try to dig, and just reboot. Reboot took over 5mn. Then, phone kept screen off; I knew the phone was working: received a phone call; power button was working fine because long press on it could light the flash (Xposed customisation); volume buttons also work fine. After long press power+volume, I could reboot, and during reboot, the screen came one again. Screen could turn on each time I rebooted. After boot was completed, if I let screen timeout and go of, no way to turn it on again.
If I don't let screen go off, and keep it busy, and try to use my phone:
- background image animation lags a lot
- tactile screen works almost fine
- apps are responsive, but viewing on screen lags a lot.
- all system tools report a good iddle time, low load, and available CPU and RAM.
- the whole phone behaves like when it's over-heating, but temperature was low. The problem was perfectly reproductable during several hours.
- system behavior could also be compared toa computer working with full software rendering, without any hardware acceleration. CPU and RAM feel good, CPU reports iddle time, but graphics lag.
Power button was working fine on hardware side because i could use it to force reboot, and switch light on. But power button could not turn screen on. Hardware of screen was working fine, because after reboot, i could get a working screen. But, how could a simple fall produce a software issue ?
I had replaced my battery myself some time ago; so, I know that I have not glued it the way it's done at the manufactory; also I had to break tapes, and could not replace them. I have placed all screws correctly. My thoughts have been:
- CPU or GPU are not strictly overheating, but, maybe their physical connection to heat sink is bad
- maybe the battery moved a bit, and is pressing against something, deforming a heat connection, or pressing hard against a sensible component (and alter it's value)
- inertia could have pulled a cable out of it's plug; maybe there is a bad connection somewhere. Power lines had poor connexion providing too little current (or undervoltage); data line disconnected.
If the GPU is partly broken, system can fall back in software rendering, and a broken GPU may not imply a loss of screen; just switching to an other video mode.
After leaving the phone off for 1h, and rebooting 12 times, phone works perfectly fine again.
There is no way this could be a software issue.
It was a hardware issue, that had very little impact on something, and fixed itself after some hours.
May not be GPU itself, but really thinck it was "video related".

Left Side gets Heated

I was reading on the Note 8 the other day and started noticing that the left side of the tablet gets pretty warm/hot. Is it just me or does anyone else have this issue? The rest of the tablet remains cool- just the left side around the middle.

This issue already discussed before. It is quite normal for a device to get some heat. Anyway, I think there is a big difference between warm and hot. If your device really gets HOT, then it is a problem. My device gets warm as well as you described, but I wouldn't say it gets hot or uncomfortable to hold. I think the temperatures quite similar to my SGS3.
CPUs and GPUs put out heat. Batteries put out heat. The more intensive the activity (particularly watching video, gaming, internet use and GPS) the more heat will be generated. This is a fact with all tablets, and computers in general. I'd think it was strange if the device didn't get warm somewhere. Heat on the left side is completely normal, although not sure what component (CPU, battery, etc.) is located there.
Now its impossible to tell what OP means exactly by "warm" or "hot" as this are not quantitive in any way. It shouldn't get hot enough to be uncomfortable (or even hurt) to hold in any way. Excessive heat may be an indicator of a faulty battery or some other hardware defect. But usually not. And the device will shut itself down long before a temperature is reached, that will hurt anything (if that is what you are worried about).
There are ways for the system to tell you the temperature, but I think its only at one location (CPU?) which may not be the problem area. So measuring this way may have limted usefulness in real life.
That is the location of the cpu unit so I wouldn't worry about it unless it gets very disconcertingly hot.

Im using the Sansung OEM cover. Holding it in portrait mode, mine gets "warm" on the left side near the edge... but only when its in my pocket and its in sleep mode and wifi is turned off. Kinda fels like my BlackBerry when its polling for a tower, it gets real warm. I have a N5110 wifi no radio so trying to determine why the warm up.

Hey thanks for all your input guys. It's good to know I'm not the only one experiencing these problems. So far, I don't think it's bothering me to the point that I wish to call Samsung up for a replacement. It does get a bit warmer especially if I have the pen out and writing some notes. I do also understand it's more than likely that the cpu is located there but I've never had a warming problem w/ other smartphones and tablets I've had.
Either way, thanks for all the input!

I agree with you, my father's got an iPad mini and the gadget doesn't present warming problems and battery life is much better. Do you think all Note 8 devices present the same problem?

Heating up near home button.

I've been having an issue lately where my S3 will get pretty hot to the touch right above the home button on the screen. The last time this was happening was when I found out that my SD card reader is apparently going bad.
Is it possible that the SD reader is still causing the heat or is there another cause?

that could be but i don't think so as the card slot is higher in the phone. all of the antennas are at the bottom of the phone and if my memory is right so is the cpu. if you are using the phone longer then normal the cpu will heat and make the phone warm front and back also if you have bad cell signal, your phone will turn up the power to the antenna to keep the strongest signal and in turn use more battery. some phone cases can make the phone warmer then normal too. i had a rubber case on an old hd2 phone and after using it for bit it was really warm. if you have just changed or put a case on your phone, maybe take it off and see if it still heats up. just a thought. worse case, i think your phone is going to let you down when you need it most due to being fried from excess heat. if you can't find the reason, take it to sprint and see what those wonderful people say.
The SD card slot is right in the area that I'm talking about.
I'm about to order another battery since my battery life has been kinda crappy lately. I've had the phone for over a year, so it's probably about time to order one.

The exact same thing was happening to my s3 since the first day I got it. It didn't happen to my dads which he got on the same day as me. This excessive heating happened both on touchwiz and aosp with and without the buttons lights turned on. Sprint told me it was normal so at that point it was whatever I got used to it. I'm pretty sure the excessive overheating from doing literally nothing (on debloated aosp roms) eventually destroyed my sd card, I believe.

Gents normally the Device should only feel warm to the touch after extended use. By extended I mean over 45 min, an hour, or more. Even then it should not feel so hot you need to put it down. If your Device is feeling warm near the top of the home button, you may want to Un-Root and take it in to be looked at. If you want to see some pics of the inside of the S3 check out THIS thread.

Battery Drain

I got mine from Three UK on a plan yesterday. Had one update and installed the usual everyday apps, Gapps, social media, android wear and a couple of games.
Went to bed with around 40% of juice left, closed all the background apps and went to bed. Woke up 6 hours later and phone was dead. Charged it this morning and monitored the battery. Said that it has only 8hrs left from full charge ?. Two hrs later down to 75% with very minimal use and with battery saver on. Nothing I could see that was draining the battery.
Has anyone else had this kind of battery drain or similar? I spoke to Razer Support live chat, told me that I was the 1st one to report this issue and that it shouldn't be happening. They said they'll email me today with a solution or next step.

Not always. When it was on battery saver mode it wouldn't be. But the point is that it was draining even when the phone was locked.

I kept background apps closed. Looking at the battery settings, the screen was the main drainer, 13% with screen on time of just over 2hrs. Other drainers were 3% and below: android OS, Android System, Mobile Standby, phone idle, Google services, Chrome, clash royale, WiFi.
I tend to ignore my battery for the first 2 days of a new phone. Because of the amount of apps being set up and accounts syncing and such. If it is just as bad after a couple of days, maybe a rouge app is hogging the resources? A factory reset would be another option to try
Obviously is it entirely possible that it is a hardware issue, but I'd be surprised.
I haven't done a factory reset just yet but will do it once I've tried everything else.
Something interesting has developed though. I took out the sim card and micro sd card and the battery draining has stopped, but WiFi still on. I actually realised that micro sd card wasn't even being detected, so I checked if it's even working, ended up being fried I think as my PC wasn't detecting it either.
So now I've inserted a sandisk, which was detected and needed formatting, but in the end... "This device does not support SanDisk SD card", is the message I got. (shrugs shoulders)
So now I'll just insert the THREE sim card again on its own and see what happens. I'll update in the morn.

What?!
What's the sd model number?
Don't mean to rub it in your face but battery life has been fantastic for me. All settings at max 120hz, 1440p and 3/4 brightness manually at all times.
I don't have the app usage screenshot anymore, deleted it like a div by mistake, but I had a flat line for 9hrs when I slept and didn't plug it in, only lost 2% overnight so could be a dud unit for you if you can't find a software problem.
I got 7hrs screen on time

SanDisk Ultra 64gb class 1. I believe it stopped working on my Note 4 last year though, strangely it is detected by my PC and I was able to salvage the data.

I got the 7hrs screen on time on my second day of use.
The phone was unplugged and running on battery for 31hrs, 9 of which were while I was sleeping where it lost 2% battery.
Before and after that time what I was doing with the screen on was Reddit, YouTube, Chrome, Twitch, listening to Spotify with my Bluetooth headphones, telegram messaging and the like. I don't have any social media accounts so no drainidge there. Really just general use like I would normally use my phone. The games I played were Titanfall, Shadow Fighter 3 and Monument Valley. Think the games totalled around 1hr20mins total but like I said I don't have the screenshot anymore.
Just a quick update, 5hrs later and now on 77% with 18 hrs left. The first hour and a half was on airplane mode with the sim and sd cards inside, which drained 15%. Then I took out the cards and only reinserted sim, and drainage stopped. Haven't really done much on the phone but does this sound like it's on the right path of battery drainage...?
Update...
So battery seems to be performing normally now it seems (refer to screenshot).
Now the question is...
Should I get this unit replaced? As I wouldn't want this issue to return in the future. Yesterday I went to a Three store and told them about it, they were willing to replace it there and then but were out of stock (and I didn't have the box with me). I have no idea what caused this rapid battery drainage, whether it was the sd card or the actual battery being faulty, but I wouldn't want it to happen again.
Which sd card are you using now? I guess the drain could be explained by bad code and engaging the sd card.
If it attempted to connect to the sd card all night long, that would surely suck power.
I would probably coordinate with customer service, return to 3 but have it sent back to razer to be analyzed. Gove razer the serial etc so they can identify it.

At the moment I'm not using any sd card. But the one that was inside at the time of drainage is attached. I think I had it less than a year. This phone might have fried it somehow perhaps, coz it worked in my mate 9.
I'm gonna put it back in, to see if the drainage occurs again. Either way, I think I'll take it back to three, as I've got two things to vouch for to get a replacement, the obvious and the phone frying my sd card, which resulted in loss of data.
Looks like a fake card. Is that the one u said ur note 4 may have killed?
Please contact razer though so they can get it when its received, best to get them involved so your problem doesn't get lost in returns, let alone driving cost of the units up.
I could definitely see a fake card causing battery drain. Hardware reports its a certain size and then an address request just continually times out.
Were you prompted to format it when you put it in? Did you let the phone format it?

No, this one I only bought less then a year ago. The sd card which was killed by the note 4 was a SanDisk Ultra 64gb class 1.
Strangely, I wasn't prompted to format this fake one in the photo, hence leads me to thinking that it was killed by the razer. However, I was prompted when I inserted the SanDisk, and after formatting, either of the two options, it did not work and showed an error.
I've now inserted a 3rd sd card, looks just like the fake one on the photo, but 16gb. This one was recognised and worked fine, I can see all the data on it. Had it in for 10 minutes, dropped 2% so far. I think there might be an issue with the sd card reader inside or something.
I guess it might matter too about exfat vs fat vs fat32 vs ntfs vs whatever other linux partition types there are? I can't recall them all, but I can't believe a sandisk sd wouldn't be accepted. That's like a car accessory company saying they won't make something for Fords. :/
You happen to have a walmart around where you can spend 10-20$ on another sd card, insert into pc first, maybe format it, scan for errors, then put it in the phone with a few test files on it?
I'll be able to answer this stuff if customs ever decides to put our US shipment through lol...
I would go with 60hz refresh rate and 1080p to get better battery on the razer, even at these settings its very fast no lag, if you do this also check performance in gaming settings to better battery, but honestly i have boughtboth phones lg v30 and razer and i cant see any difference between them the lg v30 and razer ,both are just as fast as each other, i must admit i like the adoptable storage on the razer as lg has locked this out again!!
