GSM unlocked, high CPU usage all the sudden - Sprint LG G5 Questions & Answers

Anyone ever have this happend? I have mine GSM unlocked via the hiddenmenu APK and have it on T-Mobile. Anyway all the sudden today I sat the phone down for about 2 hours, picked it up and it was completely dead, had maybe 60% left when I sit it down. Anyway charged it up. Was on for 5 min without touching it and it was hot to the touch and battery had dropped 10%. I downloaded a CPU app and seems something was constantly using 80-100% of the CPU. I had nothing rouge installed or nothing out of the odernary. This is a secondary device so it does not get heavy usage etc.
I reset the device and everything seems to be fixed, but my question here would there be anything Sprint wise thats attempting to do something? Its been about 2 weeks since I set it up. Was not sure if it was maybe trying to constantly activate and not telling me? or something Sprint ID related? I cannot disable the Sprint caller ID and it does seem to make numbers show up weird when I get calls since I unlocked it like its trying to use Sprint ID lol.
Anyone run into this? That would be the only thing I could think of would be some sprint app/built in app.
Thanks

I have an LS992 provided by directly by an LG service center; factory locked to Sprint but without any bloatware apps. Also set to GSM LTE via hiddenmenu method. I've not noticed any significant drain or odd behavior in the dialer as you describe, so it is a good bet you have a rogue Sprint app(s) assuming hardware is all fine.

Yeah I reset and things are so far back to normal. I just hope this won't be something I'll have to reset every couple of weeks because of it haha.

Update: After 2 resets, This issue is STILL occurring at random times, and usually only after using the phone, I put it down no apps running, but CPU pegged at 100% until it suddenly feels the need to go back to normal. I guess I'll end up selling it, Really liked the phone, but this is highly annoying. Seems this issue would be even more worse if it got used as a main device.

Random Restart

So far today, my Evo has reset itself about 4 times. That is within the past hour and a half. I've had it since Monday and had no other issues with it doing this until today. The only app that was added in the past 24hrs was the Wireless Tether for Root app. I don't know what or why this is happening. I've just uninstalled Unrevoked, Superuser Permissions, the Overclock Widget, and the Wireless Tether to see if that is causing the issues. Anyone else have anything similar to this happening?
Also, I changed the "always on mobile data" setting to off yesterday. That increased my battery life dramatically. I was able to leave the phone on for a solid 11hrs with it still having 60% charge left. Then today, before I changed any settings at all, unplugging the phone from the charger for about 2hrs has resulted me in being down to 45% battery. Could mobile data always on being off cause the rebooting issue?
Same thing was happening to me when I unchecked that. Checked it back and all rebooting issues went away.

Since I posted that message I had two more reboots. Just ticked always on mobile data back on and am waiting to see if that stops it...
EDIT: No more reboots since reenabling mobile data always on...weird
I've had the always on data feature turned off since day one to conserve battery life and i had not experienced the random shut offs until yesterday. Since yesterday however my phone has restarted itself no less than 20 times. Several times while I was sleeping so this is defiantly a real problem but I dont think its related to settings. ill be contacting HTC tonight
I have had always data off, ticked it on this morn. And started getting the reset issue...

Random restarts are often indicative of the battery not sitting in properly.
Remove the battery. Scratch up the contacts. Insert back firmly...
I am also having this same issue. I turned my phone off this morning because i wouldn't be using it and then i turned it back on in the afternoon and then my phone just started randomly restarting itself. There is no rhyme or reason to it. It has just been happening all by itself. It has probably happened 10 times in the last 4.5 hours.
I took the battery out for a minute and put it back in to see if it will stop the issue, but i'll have to wait and see. However, when i did turn the phone back on i got a weird pop-up message on the main screen that said something to the effect of, "Operational failure, please use su command." Then it faded away. Anyone know what that means?
As mentioned above, turning always-on mobile back on, took care of my restart issue.

I'm getting the same issue. At first i thought it was ATK, so i uninstalled that. Then I though it was lookout, so I disabled that. But it still keeps happening. I have mobile data off too, but for days, and it hasn't affected it one way or the other.
The odd thing is, I was running xiiLive Lite last night streaming the radio all night, and my phone stayed up the whole time, while plugged in (at least 8 hours).
I don't know what the deal is, but my phone goes about 24-48 hours without a spontaneous reboot, and then it will start doing it 4-6 times a day. Anyone have a good logging tool would be nice, as I'm somewhat new to Android.
Thanks!

I had mobile data off for a few days with no reset issues. Then I installed a few apps from the market (not the ones you mentioned) and then the resets started. I uninstalled the newest apps but the resets kept happening. Then I turned mobile data back on and no more resets in the last 24 hours.
my evo is randomly rebooting and I never modified the settings that some of you are talking about. My also gives me random issues where when i try to open an app it will open for a split second and close? I am also having my phone lock up on me several times a day and i have to pull the battery to reboot it! I took it back to the sprint store and they insisted on reloading the software on the phone and it made no difference.... does anyone have any suggestions or similar issues?

I had the apps closing after a split sec too but I found out that it was for apps that didn't play nice with the snapdragon cpu; like the Gameloft game Nova and a few of their other titles.
for me its stock apps like the navigator, video player etc. I am thinking i might have a defective unit.

Yup! That does sound strange! Did you root your phone? I'm rooted and all the stock apps that I've tried, seem to open and work fine.
nope! not rooted, 100% how it was out of the box. Luckily my pre was still active so i video taped it freezing up and stuff so im going to show the tech at the sprint store so hopefully they can order my replacement.
I also have a fully stock phone, some apps installed, but none recently, and yesterday it rebooted itself, twice more today.
I haven't changed the settings mentioned earlier, and haven't done anything I can think of that would cause the rebooting.
I am also having issues where I can't get an IP address on my wireless network, but I'm not sure it's related. I just noticed these 2 problems in the last 2 days, and it's the only thing I can think of that's out of the ordinary from the weeks prior to this happening.
I think I'll take it to Sprint tomorrow and see what they have to say.
Keep us updated on what happens. It seems to take a day or two for symptoms to start, but when they do it goes crazy rebooting!
...more discussion on this issue has been going on here too: http://forum.xda-developers.com/showthread.php?t=702379
I'm not a professional android user and don't know much about it yet, but mine's rebooted a few times as well. I haven't rooted my phone but the ONE thing that seemed to have resolved the continuing issue is doing a hard reboot:
Menu > Settings > Privacy > Factory data reset
It's been 4 days and hasn't rebooted since.
EDIT: It's been 6 days now and still no reboots.
Angry Apps Eating my RAM!
I think what everyone is missing here that maybe the root of the problem is low memory.
I'm not talking about storage on the SD card. I"m talking about the memory the OS has to run.
I've fought long and hard with this low memory problem seeing as I have owned a g1 for almost 2 years.
THERE IS NO REASON THE EVO SHOULD EVER GET DOWN TO UNDER 30MB OF SYSTEM RAM!
I equate this issue to the same issue many people had with Windows computers and applications that start up in the system tray! We don't need most apps to run in the back ground on start up just in case I want to use it. The few seconds of time it shaves off of starting up the app is not worth the slower OS boot up (applies to Windows mainly) or the major slow downs they cause the OS's to have.
I don't need Sprint TV running on boot!
When I used a clean slate scene I still have all of these same issues. Random reboots, slow OS and apps, ect.
I have no idea why Android would allow that much RAM to be used for background apps. I don't understand why we have no way to see what programs run on boot unless using a 3rd party app.
Most apps are so crappy that they run in the background all the time and have no way to toggle if they run on boot and I'm not talking about apps that modify something all the time I"m talking about apps that ONLY need to be running once you open them. An example would be Swipe, I understand the need for that app to run on boot. It modifies the OS keyboard and would need to be running in order to work correctly when ever you enter any text field that pops up the keyboard for input.
An example of programs that don't need to be running on boot or should at least give you an option to toggle boot start up are; Sprint Navigation, Sprint Updater (No idea what this is for), Updater (Android?), Sprint Zone, doubletwist, SprintTV Widget (I'm on the clean slate profile with NO Widgets), VoiceMail (I use Google Voice, is this needed?), Sprint Football Live (It's not even Football season!), MP3 Store (I have yet to use on the EVO but is running just in case, thx), as well as many others.
I have 35 apps running in the back ground! WTF? Thanks ****ty app devs and bloatware Sprint!
Have fun try to find options for each app and figuring out each service to know what it's tied to so that you can have a phone that it powerful and run smoothly.
It really shouldn't be this hard or as much of a pain...

This is where I am so lost with Android. I read many blogs saying Android does not need a task killer and using one will only make your system slow down. Well I tried one anyway because it's in my Windows Mobile nature to do so (old habits....). I noticed that I too had 35 or so apps running in the background and I thought that doesn't sound good, I wanna kill them all. But then what Android pros keep telling me is to let them be and that the OS will kill them as needed. But from what you're saying, it sounds like the OS doesn't always do a good enough job. So my confusion and learning process of Android continues......

[Q] Epic 2.3 - Random daily lockups and very hot.

I have a Epic that I did the FroYo update to months ago. Now it seems that at least 3 times a day I notice my leg burning, letting me know that my phone is locked.
I know it's most likely some 3rd party application on the phone but can anyone let me know how I can debug the problem rather then reset the device to factory? I also want to be able to let whatever developer of whatever app know whats up.
I also get the other random lockups where nothing will work but the bottom buttons will light up. both will happen on or off the charger.

Personally, I would start over. Wipe everything and reflash the rom. I reflashed the rom twice. The first time I had a few issues, the second time made the phone smoother. Also the second flash was with no wipe.

Since you are on Froyo (didn't say if you were rooted or not) you can run some apps like Spare Parts, OS Monitor or CPUSpy to see what is running. You can also go to Settings>applications>running services to see what is running and actually stop applications there. So if you check running services and see a third party app running that you are not using, stop it and see if the phone runs OK. Another thing you could try is to set all syncs to manual such as Facebook, Twitter, Google talk or +, email...applications trying to sync in a low signal area may cause excessive heat and the heat itself will cause FCs, freezes and reboots as the phone has a battery temp safety in it.

[Q] Random Reboots when not on WiFi

My Evo has been rebooting recently when I try to use an app that is data intensive while not on WiFi (Twitter, Facebook, Navigation, etc...). At that point, I get stuck in a bootloop. The phone will reboot and load fine until moments after the SD card is prepared. This will continue on until I reboot my phone will being within a WiFi network I've previously joined. Its a very odd behavior and I can't figure out why its happening.
I've tried wiping everything, multiple kernels and even swapped roms to see if it would help. Nothing seems to work
Phone setup:
CM7.1, 0808 radios, V8 script, Tiamat 4.0.8 SBC, no under/overvolting
Any ideas?
Does your phone get very hot? I'm already thinking a big possibility is hardware. Try a new battery

Nope, the phone isn't getting hot at all. I put in my Seido battery today and will see how it goes. This is pretty frustrating.
Just wanted to follow-up on this thread in the event someone else runs into this issue. In short, my Evo is being replaced since this was due to a hardware issue. I unrooted and went to the local Sprint store and they are replacing my phone free of charge.

Chime in if you recently are getting random reboots/bootloops/"optimizing apps"/etc

Chime in if you recently are getting random reboots/bootloops/"optimizing apps"/etc
Over the past few days my G4 has been infinitely more laggy that before, and then started getting random reboots, bootloops, and occasionally would "optimize apps" at startup multiple times in a row. When it shuts off on its own, 50%+ i have to do a battery pull to get it to start again and then it may bootloop or never even make it past the LG or the AT&T screen.
At this point my phone is unusable and a warranty replacement is on the way. It wont stay on for more than a few minutes tops. I'm getting fearful there is some flaw that is emerging if other people are experiencing the same thing around the same time.
This is on an AT&T 810, rooted on 10e firmware.
If you're also having issues, list your model/firmware as well.
Thanks,
yes!
I literally just had the same type of question haha! http://forum.xda-developers.com/g4/help/optimizing-apps-1-233-rising-t3224808
I have the H815, running on 10b firmware
Its so strange i hope someone can help!
Do you by chance have xposed installed? This started happening on my Note 3 after I updated to L and installed xposed. If not, I don't know the problem but if it's xposed, prolly have to remove it.
I had this happen to the point where the phone wouldn't boot up anymore, it would hang on Android, and then fade to black. I sent this issue to the sprint store and got a brand new LG G4 in 5 days. Just get warranty and say the phone won't turn on, and get a factory fresh LG G4 in a week or so.

Have a warranty on the way, my concern is the warranty phone will be on a later firmware with the anti rollback counter past the point of no bootloader unlock in the future. We shall see. Shame its working out this way.

Some ideas
YES. I joined just to post this reply lol. I have an unlocked H815 (Bought from Amazon, included documentation was in Czech, Slovak, and English) and I've been having this issue for weeks now. I couldn't find much on google and thought it was just my device, but now it seems more and more people are having the same problem. It is incredibly frustrating and it hurts.
Symptoms:
- Randomly (6-7 out of 10 times I want to use the phone for whatever) it'll throw itself into a reboot frenzy til it decides to stop doing it whenever, usually after 5-15 reboots or about 5-15 minutes.
- During the reboots, sometimes it'll reboot even before the phone boots up at all (on the LG boot animation).
- And for the times it does boot up, it'll reboot again within up to 20 seconds or so.
- Some reboots are immediate - phone shuts off and turns on again immediately randomly. But for some reboots, the phone freezes briefly before the reboot. On some of these freezes, there's a horizontal screen glitch at different heights every time.
- During the reboots the phone overheats considerably.
- The battery drains very quickly during the reboots. Percentage "skips" occur frequently.
- It also sometimes "optimizes" apps...
- The number of apps it needs to optimize for whatever reason can be different (I pulled the battery out several times when it was "optimizing", and the number would vary; though it did not boot at all until it finished "optimizing" apps, which took forever).
- Not sure if related, but just 3 days ago completely out of the blue overnight (no updates or anything) the camera developed a green blotch on the upper right-ish side too; seems to go away or get stronger depending on lighting. On google I found a Taiwanese H815 having an identical problem too so it can't be a hardware problem; also due to the fact that it almost immediately disappears when a different camera app is launched under the same conditions (such as Snapchat).
Device:
- Unlocked H815 European model.
- Kernel version 3.10.49
- Build number: LMY47D
- Software version: V10d-EUR-XX
- No root. No unlocked BL. All stock except the launcher (Nova). Plenty of storage space.
- Network is T-Mobile and have a 32GB MicroSD inserted.
What I've tried so far:
- Tried using the phone without SIM card. Did not help.
- Tried using the phone without MicroSD inserted. Did not help.
- Factory reset and immediate restore from LG backup. Did not help.
- Factory reset and no restore - only contacts. Seemed to work fine for almost a day, then problem came back. Probably a coincidence it ran okay for a bit.
- Since the phone overheated and the battery drained very quickly during the reboot spells, it stood to reason that the CPU was being stressed considerably. Most likely by some app or process obviously.
- Tried disabling some "stock" apps after a clean factory reset (the stock apps were the only apps on the device). Tried Google Play Services, and most other Google apps. Tried a few LG apps too. None worked.
- Tried updating some "stock" apps after a clean factory reset; same apps as above. None worked.
- From developer menu, enabled "Show CPU usage". The goal was to see what processes are running during the problem to see if it's associated with a memory leak or a CPU stress. No process seemed to stand out. No memory or CPU leaks as far as I could tell.
- Enabled event, kernel, main, memory, power, radio, and system log from hidden menu (277634#*# -> SVC Menu -> Log Service -> Log Enable). After a random reboot, copied log files to sd card from the same menu in hidden menu and tried to analyze them to see if there was a smoking gun. Logs are huge and I merely looked at the end of them, but to no avail so far. Interestingly though it seems the kernel log was cut mid-line on the last entry...
- I also noticed that after a factory reset, if you opt not to restore from a backup, the phone requires an internet connection to be set up. After the phone is ready for use, the Software version is listed as V10d-EUR-XX. The phone did not ship with this version. I believe it was V10a. For whatever reason, even after a clean factory reset, the phone runs the seemingly latest Software version. Not sure if this information is of any use, but it may be relevant.
I love this phone and when I got it, it was working absolutely flawless. Now with the software updates it seems it's just gotten buggier by the day to the point which it's pretty much unusable now, very disappointed. Hopefully this info will be useful to some of you out there.

TLDR;
-Not Rooted/Not BL Unlocked
-Reboots/Bootloops/Optimizing
-Resulting in "not fixable" Bootloop
-Phone in Warranty/Brought it back to retailer
-Don't know which Firmware
-H815 unlocked
-Messaged LG-Customer Service Conversation translated to english in Thread
Really not impressed by LG so far (First Lg Phone i own).
i think i'm gonna chime in....
these kind of things happened on my fellow G4 user here (H818P)
one of them have found and proven that on his V10D H818P, if the phone stays on for longer than 30 minutes, every reboot will start as optimizing apps
and one of them had worse luck: he was laying his G4 on his work desk and when he's about to open a newly arrived text message, the phone suddenly reboots and bootloops until no end.
thankfully one of them got the mainboard replaced, while one of them is still waiting for the warranty to be processed
Same issue is happening with my H815 now - unrooted and no modifications. Constant reboot loops or if it does boot up, it'll shut off randomly and go back to the reboot loop. Unfortunately, I have the Taiwan version and live in the US, so I think warranty coverage is not likely.
wow.. I just got this phone yesterday and i'm getting this bad. of course it was from a 3rd party seller... no fun

New recalled Note 7 - Issues with Media/Lag/Wifi/Heat

Hey all,
I'm becoming increasingly frustrated with my Note 7 (recall replacement one).
1. It lags like HELL! I've done all the animation scaling off/force GPU rendering etc, but I shouldn't have to. Just a simple thing like pulling down the notification bar noticeably lags every couple of times.
2. I use Android Auto, which I always have to reconnect manually to use (never did on the S7).
3. When listening to Spotify over Android Auto, I occasionally get stutter/glitches in the sound. Once the glitch was so bad the phone froze and it had to be reset.
4. The thing gets hot. Annoyingly hot, even if I'm just browsing Chrome, or reading G-mail etc. It's not like I'm gaming!!
5. WiFi is very sporadic. The connection is rock solid, but often it will be downloading an app...sit at 100% of download and progress no further. This happens quite frequently.
With all the above, (bar number 2), none of it applied to the pre-recalled Note 7.
I'm frustrated to say the least. Does anyone else get any of this whatsoever? I can't go through not having a phone again, or sending this for what Samsung will insist on a repair. This phone is jinxed and I'm gutted.
Any suggestions (bar a hard reset haha) will be greatly received.
PS. I have disabled loads of apps with the AppDisabler to try and help it along but I think there's an issue with the RAM or some of the internal modules (at a guess). Thanks all
I have just managed to reduce the lag quite a bit by uninstalling Samsung Good Lock (which was forced upon me earlier today)! I liked it, but serious lag creation!
Did you use Smart Switch to change phones? I've found quite a few apps don't like to be transferred. Android Auto apps don't move right via Smart Switch and I had to uninstall/reinstall them.
Be careful what you disable. Some of Samsung's seemingly benign system apps are called by other apps and if they don't respond are constantly polled. That could cause a lot of background processes and may be a source of your overheating. My pre-exchange phone did what you're describing the first couple of days after I set it up. It would maybe once or twice a day get blocky when scrolling as if something was running in the background. The (U.S.) PH1 update made it go away. But we're S-820 in the U.S. and I think you guys are Exynos. So different problems different solutions.
Thanks for your reply Barry. Actually not Smart Switch, but I let it restore my 100+ apps from my previous Note 7 (near the end of the initial set up). The apps were downloading but strangely, every so often nothing was happening after they'd reached 100% downloaded, just before "installing..." (over WiFi). I cancelled that specific app and the restore continued (this happened over and over). Turning WiFi on and off sorted it temporarily but I couldn't download more than 3/4 without this really strange issue.
I also observed the longest lag ever! I went into the OS update screen, pressed update and the device didn't respond. 5 mins later while doing something completely different, the update screen popped up about 12 times (as I'd pressed it 12 times 5 mins previously). This happened again after a reboot too!
Now, I've just bitten the bullet and performed a hard reset. This time the WiFi seems great, although now I'm speculating that it was getting stuck at 100% post download perhaps because the security thing was having trouble scanning it for malware prior to install.
I also take your note re:disabling stuff! I'm going to do something unheard of and just try it stock for a bit and see how it goes. For such amazing hardware, the fact my note 3 was running 10 times smoother means something drastic is going on. I hope this hard reset is the end of it!
Chances are the hard reset won't do anything, though I hope you have better luck than I did. I went through three phones (on my 4th). I did the hard reset as soon as I picked up the 2nd handset and onward before I did anything with the phone. Sadly you should not have to disable anything, the phone should just work for 900.00. Some will say otherwise.. Wi-FI is good for me but the reception is garbage. On various phones with T-MO including other android devices that colleagues have - they get 4/5 bars and usually double the download speed on Speedtest. The head I had on the first I don't get as bad on this one. But the lag I do...
Did you get the update from your provider as well?
I just picked up my replacement Sprint Note7 today so not much time with it though seems identical except 1 small issue. I had my first Note 7 rooted, Viper4Android and Dolby Atmos flashed along with Xposed and it worked flawlessly. The replacement Note fails with binary invalid using the exact same odin version, Sun7 systemless root etc that I have on my pc from the first Note 7 and the second Note 7 was given to me not updated, in other words its on the exact same firmware as the first one!
I am very proficient with rooting, adb, etc and this has me baffled.
Has anyone successfully rooted a replacement N930p that came with PH9? using freeza's guide?

Yea disabling seems like a great idea at first but it actually creates problems. I run it completely as is except uninstalling the preloaded games. Didnt disable anything. Disabling stuff caused massive lag on my note 5 and same with note 7.
Thanks chaps.
I've gotta say, the hard reset has made the world of difference. Which to me is strange, I've never had to hard reset a new device, but it's done the trick.
Regarding the disabling of services, there must be *some* that are safe to disable? I agree if you're tinkering with potentially integral things like S-Voice it's not a good idea. But then stuff like OneDrive surely that's okay? Maybe, things like the Disabler package are a bad plan. You can disable software by default without it, but only certain apps. Maybe that's why Samsung prevent the disabling of certain bloat...?

I only disable the useless apps, such as all the Microsoft bloat (OneDrive, Excel, Word, etc), Facebook (and all its services), and any Carrier bloat.

Disabling facebook services will broke gear VR.
It's a tricky one! I guess it's a bit of trial and error.

That's cool. I have no interest in Gear VR.
I have heard somethings about latest version of chrome causing batt drain, could possibly contribute to lag also, I cant tell much as I am expecting my note 7 exchange, but I have seen some posting about it
Have no problems when I used package disabler and chose "disable all bloat"...but after doing that, I looked through the list and enabled around 3 to 5 that I thought didn't need disabling.
No problems since.
Oh...that option doesn't disable facebook, messenger, hangouts etc. So if you don't use those, you need to add them.
Thanks all. Well, after all that, and a hard reset my phone is running perfectly again. Then, this morning I received this from Oculus...
"We recently pushed an Oculus Software update that has inadvertently caused some people to experience phone performance issues."
I haven't put my phone into my Gear VR since the hard reset and I can almost guarantee it was that blimmin thing. Samsung have also updated their Good Lock app to remove lag yesterday!
Damn you Oculus!
Oh..and strangely, the first few hours I got the phone..it got pretty hot...especially since I was using it while charging. I turned off fast charging and no difference. Anyways I just cooled it down w the aircon now and then.
Long story short, it doesn't get hot anymore.
Maybe it's because I used package disabler snd greenify...but whatever I do...Even while charging..it barely gets warm...

Yea they always get very hot for the first few hours while installing all the new apps! I'm not sure you need Greenify these days do you, since android tends to close apps that are not in use (giving you the same options as Greenify)?

This. I just spent two days doing that and its like a totally different phone. I started a thread highlighting my experiences.
i am quite annnoyed with the lag too. it's nothing too bad, but there's noticeable keyboard lag, and whenever you go into settings to search for something, it takes like two seconds to load. i don't even think this is a case by case situation here, this phone just isn't as fast as a oneplus 3, lg g5 or iphone 7 plus. again, it's not terrible, it's just not the fastest or smoothest.
