Develop Bugs

Is anyone else finding their Arc starting to lag?

I have had my Arc since it first came out in the UK but have noticed on occasions of late that it seems to have developed a lag, especially on things like accessing the gallery & messaging. Has anyone else noted this?

Nope. However I do use a cache cleaner every few weeks.

Yup, after about 2 weeks mine started to lag every once in a while. I just assumed it was because of some faulty app. So I did a clean install, and 2 weeks later it was the same again. (didn't install too many apps this time)

Mine is still great.

try an app called fast reboot....I find it speeds things up

No lag at all here, 2 months in.

Had the Arc (UK) about 2 months and in the last two weeks things have really started to lag. Have had to resort to rebooting and cleaning the cache regularly but it only takes a day to start lagging again. Wondering whether there is a CPU/ memory hog there in my app suite or a widget but haven't been able to identify anything yet. Once the phone goes below 40-50MB free it is all over and I have to reboot.

This may sound weird but my phone lags during the day and it runs super fast at night lol

I have this lags, too. But I had not to reboot the system, yet...
Any more ideas?
Cheers!

After update on Android 2.3.3 i don't hve any lag. Before that I had lag but nothing to worry about. I think it was Android 2.3.2 that cousses lag.

Same here after about 1 to 2 days the phone memory goes to about 25MB and is practically not useable and need to reboot. I am on 2.3.3

I went through my apps & by trial & error ended up removing a particular app & that seems to have sped things up a bit. Also downloaded a history cleaner & used that & that has improved things a bit as well. But in certain areas it definitely still seems to lag. Have to wonder now if it is something to do with the Arc's hardware?

ok guys after using SeePU+++ i think i found the process that uses the most cpu power and lags down our Arc is "ndroid.process.acore"
not sure what it does but i believe it is the culprit for random slow downs and lag on our phone...
does anyone know what it does? can anyone confirm my findings?
P.s. I am on global generic 2.3.3 firmwre 145

This problem may be caused by a bug in the Google Contacts Sync , just as seen in this bug:
http://code.google.com/p/android/issues/detail?id=2377
In other devices like HTC Evo this problem persist

http://androidforums.com/evo-4g-sup...andom-reboots-magic-bullet-facebook-sync.html
I don't have the Google Sync activated and i don't feel my Arc Laggy

This phone is incredibly laggy. Many FCs or lags when I open the messaging app or other apps... Very sad and frustrating.

One of the major causes of lag on the HTC hero was having too many text messages stored on the phone. Ever since then i tend to not let the numbers build up too much, and i havent noticed any lag problems on the arc (maybe it's a general android problem).

one of the main android apps, your keybord and other important funtions are here, so my advice : dont touch it or you end up reflashing ROM

Not impressed with lag

I'm not sure what is causing lag, but my Note 4 had enough of it to be concerned.
Sending SMS and messages via hangouts is brutally slow, just as scrolling through Google Now and within the eBay application.
I have a little bit of stutter in touchwiz, but that isn't near as bad as the app stutter. Wondering if this is something to be concerned with.

only reports of lag I have seen are @
http://forum.xda-developers.com/note-4-att/help/noticeable-lag-using-t2909820
I have not seen any myself, this thing powers through anything I have done so far.

Same here, my phone runs butter smooth with animations set at .5 and forcing GPU rendering. Gotta love that Adreno 420
OP might have a bad device. Try replacing it to see if that fixes the problem. Very few people have reported lag and it seems to be no more then any other device.

I want to point out that I had the same issues you mentioned. I went ahead and performed a factory reset since I just got the phone and I hadn't done much to it. It solved my problem and I'm not getting any more app stutter from sending messages through hangouts.
It happens, man. Initial setup of the phone could go wrong, especially when you load on a ton of apps at once. Might not have been your fault; it could've been the devil that loaded all that carrier bloatware on it.

No lag here either, I've been running a media converter on it 24 hours a day for the past few days to change a lot of my formats to mp4s from mkvs and even with that running in the background, with encoding being one of the more CPU processing hungry things you can do, I can play GTA:SA on it without issues.

I was actually lagging pretty bad past 2 days. I enabled ART and let it go for a day thinking it would get better. I restarted it the second day hoping it would help. Finally disabled it an hour ago and its working as expected... Guess there is no real point. I'll just hope we get 5.0 before the years over.

It was good for me before, but wowee. Thank you for the tip.
I feel the power!! So much of a difference that makes

Yeah buttery smooth here. I've disabled all the ATT apps via managing applications and ALWAYS use Rechild Task Killer - by far one of the best app killers I have used over the years since Tmobile G1, Note 1, Note 2, Note 3, and now Note 4. It helps despite what anyone may think.
Also, as other have mentioned, tap your build number 7 times to enable Developer Options Menu in Settings - General. From there, you can disable animation transitions - I always set all mine to 0/No animation because I don't need animations and that speeds things up a lot.
All my texts/MMS are fast along with browsing and internet - HUGE difference compared to the Note 3 (everyone was right- that phone had the worst WIFI imaginable - I was rooted and had the same setup as I do now on the Note 4). I have my MOTO 360 connected with bluetooth always on. I use Textra as my main sms/mms app. I'm really happy - battery life is excellent compared to my Note 3 because Android Wear eats a lot. I also have 1W weather widget on refreshing every hour. I have location on power saving mode so only Data and Wifi pinpoint my location instead of GPS (this is just common sense - GPS kills your battery so don't choose the TOP high performance option).

Wow, what a huge difference. Thanks!

thats odd because I dont get any lag. The only thing I noticed is once in a while, when opening Hangouts, the GUI gets stuck at a blank screen and I have to back out and enter in again. The other issue I noticed, which doesnt happen often, is that the network gets stuck in a certain speed (i.e. 4G or whatever), when I know I should be getting LTE service. If I toggle airplane mode, it switches to LTE and works flawlessly after that. Its almost as if the modem has a hard time switching networks.

Well, it looks like my Hangout lags is back after I got a ton of auto updates today. I probably shouldn't have left auto-update enabled. There's probably an incompatibility with one of the apps so I'm going to hunt it down. Other than that, the rest of the phone is quite smooth.

UPDATE: The problem is clearly the hangouts update itself. I uninstalled the update and disabled automatic updates. It's running smoothly again.
So the problem with hangouts appears to be the most recent update. Uninstall it and you'll run off of the stock version that shipped with the device. until they've fixed the problems.
The problematic build is 2.4.78234730 (Oct 22, 2014).

And no problems with sending messages?
I've cycled installing and uninstalling it a few times to verify that it was indeed the problematic version for me. It could very well be an incompatibility issue still, but I'm not experiencing problems with other apps... aside from Instagram being awfully choppy when cropping photos for upload.

touchwiz always lags. the lg g3 has significant lag to.

I did a factory wipe, disabled all the bloatware i could, forced gpu rendering and changed animations to 0.5x and honestly, it ive been good to go. i did all this to my dads note 4 this morning as well but he said he hadnt experienced any issues yet with everything kept stock

GPU rendering is pointless. I tested the other day. The speed was exactly the same for opening and closing apps, etc. The drawback, if you have flash video enabled and watch any video, shows, movies, etc. - it will be laggy/choppy with this option enabled.

Might need a master reset. I just purchased this phone yesterday. The first phone they gave me reset itself almost 30 times on its own despite me master resetting like 5 times. After the second master reset I didn't load any apps and the issue still persisted. Went back and had them give me a new one. All is well now.

might have spoken too soon. Hangouts works fine after the latest update but i do notice a second or two lag when trying to open the keyboard or open a chat. Its not enough to really complain but it is noticeable.

Noob quesion.. Can someone please direct me to where I go to force GPU rendering on the Note 4? I can't find then setting anywhere. I've been out of the Android game for a while so I greatly appreciate the help. Really like this phone, but the lag on even simple tasks like Facebook scrolling is leaving much to be desired.
(Disregard finally found out how to enable Dev Options.. Man I got a lot of catching up to do.)

Performance drops after updated to Android 8

Hi,
I've been here for a while now but this is my first post ever.
I'm having a really weird issue: when i first bought the phone, it works flawlessly and there was nothing to complain about. However after updated to Android 8, the phone's performance drops noticeably. Applications like Facebook or Instagram always freeze after a few minutes surfing (the lag will last for a few seconds and come back to normal, and after a while it's lag again).
Even in a low-end game like The Walking Dead Season 1, sometimes the FPS drops dramatically. Never happened in Android 7 before.
I tried reset the phone, clear cache and data and stuff like that but it just doesn't work.
Switching to Lineage OS is a good option, the performance there is really fast. But the gamepad and the camera don't work stably to i switched back.
Can someone help me?
The phone is not rooted or anything like that btw.
Thanks.

Perfectly fine here, try factory-resetting your smartphone.

No problem here.
Try full format your phone using recovery.

I'm starting to see big issues with response lag (especially when typing). Anyone have a solution for this issue? I have Oreo factory on my Z2.
Thanks,
smithmal

Phone stuttering and lagging more each day

Anyone also experiencing same issues? After the PIE update months ago, everything began going downwards. Scrolling sometimes getting laggy or sticky (like pulling a gum from the ground), stuttering on some apps like chrome etc. Should i go back to Oreo? For me personally seems like this whole PIE thing was just a half-assed rebranded thing for OP5/5T originally meant to be devices like OP6/6T they just released half-assed update to satisfy people asking for pie update.

https://forum.xda-developers.com/oneplus-5t/help/oneplus-5t-suddenly-lagging-t3896998

You're not alone.
I noticed this straight away when I "upgraded" to pie. Very noticeable when scrolling. If you leave the phone idle for a couple seconds (around more than 20-30 seconds), then scroll again, there's a very noticeable lag.
Another user on reddit managed to capture the issue
Unfortunately there's no fix. I wiped the cache and then factory reset. Still had the issue.
I ended up just going back to Oreo, which I recommend you do if you want smooth performance again.

Same problem here, no one want to help us. Like problem did not exist

I started having this problem since going to Pie, but the phone only stutters randomly about once or twice a day for me. A temporary solution for my phone is that whenever it lags, I press the power button to lock the phone. After unlocking, the stutters go away. Let me know if it works for you.

Go to beta one

One ui 2.5 update is garbage

Just got the new update today morning, it's been a lag fest since then, one to two second pauses when opening apps, pauses when pressing any of the nav buttons, horrible battery drain. It's 2pm now and Im down to 15% already.
First screen shot is from today, second is from yesterday's usage.
Already cleared cache, made no difference.

Which app it is? Your screenshot?

Exactly what I wanted to know as well.

Regarding the topic, for me, personally, this update has been quite good. Everything runs well and I like the small visual clues and changes.

Lucky you, this is the first time an update screwed up my phone. I'll probably have to wipe the phone.

Hey , my phone has been the same, lag and stutters while scrolling and opening apps and stuff. I've cleared cache multiple times , didn't worked. You need to factory reset, it works so smooth now.

Update running great for me, I did optimize apps right after via galaxy labs however.
No lag, battery the same as it was before.

Same here....I will pass update.
My S20+ after update: battery drain, laggy scroll, laggy opening apps....
I tried all day trying to fix it but nothing....I booted in safe mode and not lucky so it is not and installed app.
I tried wipe cache...I tried disable multiple services, wipe cache and data from touch wiz, etc....nothing works.
Phone is totally useless after updated with lag and battery drain...and runs very hot
That updated is a Russian Roulette....beware!!
I will try to flash a clean rom using odin and restore apps.

my opinion , after every big update , device need factory reset and install everything from 0.
that what i did with my s20 ultra after one ui 2.5 update

S20 SD. No problem with the update.

Had the same issue as you. If you're using package disabler, enable all pkgs, clear the cache, restart, and then redisable. Worked for me

I had the same problem but in my case I got it fixed after enabling IMS with Package Disabler because I had these disabled without issues before the update.
After enabling this my S20 Ultra runs good again, so if you have package disabler installed start looking into that.
So definitely no need to reset like others say lol, it is no new Android so why would you just a conflicting going on
Btw I install updates always with first enabling everything and update all disabled ans then installing updates.
After update, running galaxy labs, cache cleaning and then disabling my list with Package Disabler again.
So don't no why IMS packages gave me issues this time....

Hmm interesting, which package disabler are you using btw? The ccswe one stopped working a few months ago.
I was just about to wipe the phone, i restored all the packages and wiped cache and so far so good :good::good::good::good:

!!!EXACTLY!!! The same thing is happening to me. Slow fingerprint unlock (its getting stuck sometimes), Slow in opening the apps, navigating back. I clreared the cache but no use. Its dam frustrating, I feel like Im using heavy software on Galaxy S5 phone

The update has been fine for me, T-mobile s20+ SC. Only thing annoying me is that they took away wallpaper scrolling from 3rd party launchers.

Has anyone had issues with automatic wallpaper apps? I use resplash to auto set a wallpaper every 3 hours. It seems everytime overnight it will switch itself to a default Sam wallpaper for no reason.

I received this update few days ago. but I have no issues, I thing even the time of battery is definitely better. software is responding good and fast.
Just two old bugs are still chasing myphone. The edge lightning ( does not work. ex: Messenger APP) and delay on gMails notifications.

My wireless charger stopped working after the update, no other issues.

Everytime my screen turns off my WiFi gets disconnected and then I turn it on and it connects again. Any ideas?

S20+ on VZW. No issues.
Only thing not working is I can no longer expand notifications from Nest, though not sure if that's a Nest problem or on the phone's end.

I feel it's noticely faster on my S20 Ultra (G988B) and battery may be the same or slightly better. Ovrerall, great update especially the DeX and Pro Video recording update.
