Phone is painfully slow, trying to troubleshoot - T-Mobile Samsung Galaxy S7 Questions & Answers

So I've had a T-Mo S7 for about a year and a half now. It's incredibly slow/unresponsive and I've spent a really long time troubleshooting.
I've done full factory resets, and direct ODIN OS installs with data wipes. Whenever I do this, the phone starts out, with all current apps installed, extremely fast/responsive. I have a somewhat limited app library, and I haven't added anything since the phone slowed down noticeably.
About two months ago, the Samsung Device Maintenance app, which until then only reported battery draining, said "Some apps or processes are overloading the system (CPU)" and the app it reported was something like com.android/google.searchbar" which I assume is the google search bar widget. I thought, "awesome, the device app is actually doing something." I told it to kill the app and my phone sprung to life. My phone was super fast for a long time, but is now back to being super slow again. I searched "Apps" in device settings and can't find any apps/processes that sound anything like search bar. Also, how is there not a system resource monitor in system settings!? Clearly, an app is hogging resources, because I've experienced periods of responsiveness. Is there no direct way to figure this out without doing the safe mode process of elimination?
Can someone help shed some light or suggest further troubleshooting steps? Thanks in advance.

I got mine on black friday 2 years ago and I've been having the same issue. Of course my battery doesn't last very long being it's over 2 years old. I'm guessing it may have some.thing to do with the battery voltage being so weak after so long. I'm due for an upgrade obviously but I'd be fine using my S7 for another year if a battery replacement did the trick. I believe I was told in chat that I could go into the store and they'd only charge me $5 but I assume they'd have to send the phone out unless they just swap it out for a refurbished one. I've had no other problems with mine at all so not really the route I want to take.
Anyone else familiar with this process? Has anyone else had their battery replaced or phone swapped and notice if the fresher battery helps or is it just a symptom of it "can't" handle the newer OS properly? Any feedback would be appreciated. Hopefully it helps us both out. Didn't mean to hijack the thread!

So I promise it's not the battery because I had it factory replaced by Samsung. To answer your question, yeah you have to send it in. With the waterproofing they have to do it at a repair center. However, for me it was 100% worth it. I think I was without the phone for about 10 days. But having a brand new battery life was incredible.
Also, as I was working with the phone slow for a while, it immediately and dramatically became quick after device maintenance killed that process. But a few months later, I'm back to suuuuper slow.

The S7 is getting old. Old things slow down. It's planned obsolescence. I've gotten to the point of turning notifications off for all apps and only using badge numbers to tell me when to check something. I also use do not disturb a lot when gaming instead of game tools because game tools is another app but do not disturb is more of an internal process. As soon as my taxes come back I'm probably going to get a S8+

My Captivate is Dying

Sound does not work
its freezing up
I have to remove the battery and replace after a power down just to get it to turn on again.
It was all working at first, didn't root it or anything like that, just a few mainstream apps.
Have had it for less than a week
Have done a reset from the menu, but cannot do a 'hard reset'
Any ideas?
I think the phone is great (ex-iPhone user), but I wish it would work right.
Maybe you installed some app that is eating up the phone's memory.
It may not work for you or maybe you don't want to risk bricking your device but after a reinstaled the original firmware my phone was better than when I first got it.

AT&T has a 30 day in store warranty. Bring it back, tell them what's going on, ask them to swap it out. Mine works great. Just go get a new one, and you should be back in business!
i was having the same problem but i installed startup cleaner and disabled almost everything from autostarting when i reboot the phone. i also have advanced task killer auto kill tasks every 4 hours and i use minfreemanager as well. ever since using these apps, my phone has been quicker than ever. you could also try using setcpu if you want.
I want to take it back, but I bought it from LetsTalk.com (got a great deal $25). I would hate to have to send it back and be without the phone for a few days.
Just a follow up:
LetsTalk was offering to cross-ship a new phone, however they said they were backordered(they claimed???).
I contacted Samsung, and they offered 2-day shipping both directions and will replace my phone, which was great.
Both customer service centers were very helpful and even though I have to suffer with a crappy phone for a few days, I'm looking forward to getting my Captivate back.
Just a note. Had my Captivate for 2 days and the signal died on it. No matter what I did (hard reset, replace SIM), I could not get a signal. My battery life was also extremely crappy though the two are probably related. Took it back to the store and exchanged. Much, much better.

Startup cleaner looks interesting. But, I went over and read reviews, and there are a lot of negative reviews.
It still working OK for you?

I'm hoping that once I get a new one, I'll be good to go. What's weird is that most electronics either work or they don't, and mine also only lasted a few days.

[Q] Atrix 2 Heat Issues

I have had my Atrix 2 8 days past the 30 day mark. And recently the phone has started getting really hot. Not when I am using but when it is just sitting.
I have checked to see what app or process could be running and causing it. And I have found nothing. This is what I have checked so far
Wifi is off
Bluetooth is off
GPS is off
Here are the only things using my power
Cell Standby 33%
Phone Idle 31%
Voice Calls 9%
Motorola Services 4%
Display 4%
And it gets smaller from there. I can set the phone down and walk away and come back to pick it up and it is smokin hot with 40% of the battery drained.
I sent an email to Motorola support on New Years. I have not heard back from them. I also contacted ATT and they want to give me a refurbished phone. Which I have refused due to last phone I did with them. I got a scratched up dented phone in trade for my flawless phone. I told them my phone has been used for 38 days and is flawless I want the same back.
I liked the phone at first but I am about at my wits end. Any ideas what can be causing this?
My phone gets really hot when I leave the camera app running.
Droid incredible 2 running cyanogenmod 7 nightly 134
I just went into my task manager and the only things that are using my cpu are the Android System at 25% and Home Screen at 1%. And my battery just dropped from 15% to 5% in 20 mins sitting with the screen off.
Download an app called watchdog and see if you can trace down a rogue app maybe. Also setcpu gives you an option to see the battery temp. Would be interesting to see what the temp is when you're saying its hot. Mine generally stays around 32° with general usage.
I am trying your suggestion and running into the second issue I having. No data. I just opened the market and it says server error. Tried 4 times. And the little 4g symbol is white not blue and I have 3 bars of signal.
I love android and I love the look and feel of this phone. But this thing is seriously p*****g me off.

I run into that issue at work sometimes myself and usually its due to spotty coverage. I have a airplane mode toggle just for it. Toggle on and off and usually jumps right up to 4G in blue
Update: Motorola never responded to my email. AT& T never called me back. So I called them yesterday and asked them why they didn't return my call like they said and chewed them out.
I tried the watchdog application and it never alerted of any rogue apps yet the phone remained hot.
So the end result was ATT sold me a Samsung Galaxy S2 SKYROCKET for 149.00 (199 was normal price but I got 50 credit for what I paid for atrix) and a 160 credit on my bill. They put a supervisor on the line who apologized repeatedly for them not returning my call.
The crazy thing is they don't want the atrix back? I asked them what about the atrix they said try to return it at the store I bought it at if I want.. Overall I am more than happy with Att's response after they dropped the ball. But I will never buy another Motorola product again. They have yet to get back to me. They sent me an email over a week ago saying they will be contacting me in 24hours and and a week later nothing.

Never had my A2 gets too hot. BTW you had a problem with ATT not moto for not exchanging your phone. If it gets too hot and your battery is draining too fast it might just be a simple battery exchange. Moto will never listen to peoples request or demand ^_^v but there are great devs here cooking up some fix for our A2's existing bugs. I think i will never get to see your problem though because my GPS, 4g/data, bloatwares, are always off and have droidwall that gives me some control on what goes out of my phone. You might want to call ATT and have them check if your phone is set to 4G because mine wasn't before and they had to configure their end for it to work properly.
Before you went ahead and exchanged it, you probably should have flashed the stock fxz and factory restored, and then reinstalled your apps one by one to ensure that there isn't a rogue app hiding somewhere on your phone.
But at least you're happy with the end result. Too bad you don't still have the A2, it's a great phone. I've never had that problem with it (but I did a couple times with my A4G).
I just got an email back from Motorola today. Also, I did factory a reset and the problems persist. I do still have the phone. I may do refurb exchange and give it to my wife. She doesn't care about it like I do. She will have it torn up in 2 weeks from throwing it in her purse and letting my kids play with it.
I would bet on it being the issue I experienced with cpu not scaling. Let me tell you that was a witch Hunt.

How did you fix the issue? My phone is doing it now. I'm getting very frustrated, I really like the phone and I don't want to get rid of it. They have replaced my battery and my phone once over the issue, and here it goes again! Any help would greatly be appreciated.
Same issue here. Phone will be in stand-by mode, battery starts to get very hot to the touch, and it automatically reboots.
FYI: To the OP and anyone else; Your phone is under warranty for 1 year. You can go to the motorola website and look up whether or not you're still in warranty.
This could all be caused by a number of things, including but not limited to: SIM card may need to be swapped for a new one, the sdacrd may be of a class that's unstable to run or has corrupted data/app data, clearing Dalvik and/or cache partition(s) may not hurt to try, if the signal coverage isn't consistent and the phone has to search for signal to connect with this will eat your battery alive and cause some excessive heat as well, the battery may be going ka-put, battery stats could be wiped, may need to try a factory reset, or it could be a hardware issue altogether. Motorola isn't manufacturing "new" Atrix 2 phones any longer, so even if you have a warranty and go for an exchange through Moto, you're most likely going to end up with a refurb phone. Moto seems notorious for manufacturing devices that do run hot, and I suppose it could also be attributed to how much the user is "using" the phone. Clock speeds also, the higher they are, will run the phone hotter, and if pushed too high or at an unstable clock speed, the device most certainly WILL randomly reboot. Sorry there isn't a more 'definitive' answer that I'm able to come up with, but trying anything and everything at this point might not bode poorly in your favor...

Battery, CPU and Message Issues, please help.

Hi All,
I've been having a number of problems over the past few weeks with my OnePlus One, not quite sure what to do so I thought I would ask here for any advice.
Overall my major problems:
High CPU usage (and therefore high phone/CPU temp to the point of needing to turn off because of overheating)
High battery drain (and the battery will not last 5 hours even on sleep)
messages take between 1 ~2 minutes of hanging to send.
Phone randomly waking in sleep (contributing to the battery problem?)
I've looked into it a bit, I've disabled the Google Play Services from waking in sleep, cut down and uninstalled most apps. I've let it drain completely and left it off for 1 hour before charging to full and turning it on. I've tried to do everything people have suggested and nothing so far has worked.
My Phone Build:
Completely Stock CM12.1-YOG4PAS1N0 [Installed through OTA]
Kernel version 3.4.67 - untouched
Never rooted (I've been lazy), no custom rom, nothing touched in bootloader
Always kept safe, no damage, no water damage
I am thinking of doing a factory reset to see if that solves the issue, right now just looking on a way to backup all of my sms/app data (since I can't even titanium because it's not rooted) [All suggestions welcome if you have any good backup software/app that I can use on unrooted phone]. I do suspect a possible virus, hence the want to factory reset, especially about the messages taking so long.
Any help is appreciated, thank you in advance.
Happy to provide battery log or anything if necessary.
Thanks!
Hey there,
I'm so tired of talking about this topic that I can barely work up the determination to write this response. I'll give it a go though and I'll try to keep it short, simple and leave as much emotion of as possible.
So I've had my phone 10 months now. It seemed great at first but it wasn't long before I started seeing cracks (not literally). It began with the battery, or lack thereof. These days it's much worse but even back then it was noticeable worse than any other phone I had owned in the past. I first reported this issue... 6 months ago.
I'll leave that to sink in a little, before telling you that even now my issues are still not solved and I am having to take OnePlus to Trading Standards and receive third party consultation and legal advice.
So six months I have complained and begged them to solve my problem. And in that time my phone has gotten significantly worse.
It exhibits the EXACT same problems as yours. Down to the last note.
The battery... *sigh* Oh the battery. It now lasts around 1 hour of heavy use, 2-3 of moderate use and a bit more otherwise. Even if I leave it completely alone I have to charge two to three times in a 24 hour period.
The CPU seems to be randomly throttling. Performance from app to app will be vastly different.
The heat that comes off this thing is obscene. At times I literally cannot touch the face of the phone or the camera lens they are so hot. (I remember recording some temps once at 47 degrees centigrade).
My messages generally either send or don't. Or maybe I don't wait long enough. I just usually copy the text and resend anyway.
I have issues with my touch screen responding. Funny I never had these or never noticed them when everyone was shouting about it. Now they've released a fix I have them.
Some Wifi networks do not work, they get stuck forever "Connecting".
The phone no longer rings, vibrates or gives any indication of incoming calls. Sometimes it'll pop-up on screen, sometimes there will be literally no indication even on screen except that my phone wakes itself up to the homescreen and then minutes later tells me I have a voicemail (which also has no notification sound/vibration)
As it is I have finally, just this last month been offered an RMA... YES that's right, it's taken them six months to own up to an issue and offer me that which is stated in my warranty and within my rights.
Unfortunately, for them, it is no longer good enough. I have applied to my bank to forcefully remove the money from them and return it to me. That is being decided with the evidence I have, by my bank at the moment.
After that, the ball is in their court and I am free of them as far as I am concerned.
I wasted so much time and breath on emailing and tweeting them and getting no responses, stock responses, blanket responses, repeated verification processes, remote flashing of Oxygen OS to my phone by an engineer (which has brought up more problems, mainly being that Lollipop and Oxygen OS especially are godawful) and general deflection and delay tactics.
They are one the most disgusting companies I have ever had the displeasure of trusting, purchasing from and dealing with.
I hope one day, they go bust and I never have to hear of them again.
Sincere apologies for my vitriol but it is not unwarranted or untrue and I cannot abide. I am extremely sorry you are dealing with the same issues, you are the first I have heard to have the exact same concoction as me. I'm afraid we may have defective (and dangerously so maybe) devices from the factory line, but no one will own up to it.

Help me diagnose my overheating/battery-sucking D6616 (TMOUS)

All right. Let me start by saying I've had this phone since it first came out and until very recently it's been a great device for me. Yes I have the T-Mobile US version with a locked bootloader, which sucks as far as ROMS etc. go. Yes its GPS can be less than reliable occasionally thanks to issues with Lollipop, which we're stuck with. But everything else it did just great. The battery life was one of my favorite things about it- if I started a day with 60% it would be just fine.
Until about a month ago. About a month ago, the phone developed this <sarcasm>neat trick</sarcasm> where it would get really hot and burn through about ten percent of its battery or more in ten minutes or less.
My initial thought is that I'd have to wipe the phone and start from scratch (followed closely by rooting and loading up an Android Nougat ROM, but we all know how that's worked out for the D6616 ). But I'd really like to avoid wiping if at all possible.
Here are my working theories, let me know what you think I should do to further diagnose:
Some New App is Responsible- The obvious candidate. I installed GSam Battery Monitor to look into this, hoping to find an obvious culprit to delete. Sadly the only apps using more than 2% are whatever app I've been actively using with the screen on, Android System, Kernel (Android OS), and Google Services. I uninstalled a bunch of unneccesary apps anyway, but it didn't improve things very much.
The New York Subway System - Stay with me here, it's not entirely a joke. I live in New York City and recently all of the stations had cell service and wifi activated on underground platforms, but not between stations. So when I ride the train (a significant chunk of my day as I freelance work in clients' homes) I'm going in and out of service constantly. And things do tend to improve when I turn on airplane mode when I get on a train. But not a lot. And the overheating and battery sucking behavior does happen sometimes when I'm aboveground.
The Battery Itself- This is the one I'm most worried about because the fix just sucks. The phone is now over three years old, and I do use it pretty much every day, only turning it off at night or when I'm traveling abroad. That's a long time for a lithium battery. My understanding is that near the end of their lives, they do overheat and lose charge quickly after a while. Since this is a waterproof phone and I'm in the US, I'd have to ship it to Sony for 2-3 weeks a repair if I want to keep it's waterproofing abilites (I do). I'm betting that's not cheap. My real hesistation with this one though, is that my phone is about as old as most other people's on here, so if this were the case, I'd expect a ton of users here or on T-Mobile's forum to be complaining about the same problems. I haven't looked closely but I haven't seen many people with this problem.
So that's where I am. Any ideas? Things I should try out to get more info? I'd really like to solve this, and I'd bet figuring out on here would help others in a similar position. Thanks!
Managed to get some relief by wiping the phone. Didn't restore it to the good old days of 60%-in-the-morning-no-problem-all-day, but was decent. But now it's come up again. I can and will wipe the phone again if I have to but if there's a more elegant solution someone has found over the past 10 months or so, I'd love to hear about it.
Thought I'd solved it when the sd card died and I wiped/replaced that. But then it started having the same problems a few weeks later on a new card. I wiped the phone and the SD next and I'm still having issues. Heck, I've even had it heat up while in TWRP recovery mode, so I'm pretty sure we're looking at a hardware issue.
My first instinct would be the battery but according to the internal temp sensors, the battery isn't that hot (39 or so C). The CPU on the other hand is getting very, very hot (spikes to 72 degrees C). This tallies with what I feel on the phone looking at diagrams of the innards: the hot part is about a third of the way down from the top of the phone, where the CPU is.
Any idea what bit would have to be replaced to fix this?

Galaxy s7 overheating

Hi there,
Have something that botheres me for a while.
My daughter's S7 started overheating not long ago and it seems to get worse every day.
Random reboots every few hours. I was next to her whrn watching a live stream and the video stopped and the audio glitched (buzzzzzzz) just before the phone restarted again. Is this the end or a software reboot can fix that? Or probably a new battery?
Still using the original software version. There has never been unlocked or installed a custom build. Of course its out of warranty long time ago.
Thanks for your help in advance.

I wouldn't worry, it'll probably explode while you're asleep taking the whole neighbourhood with it.
So the answer is, as device firmware is updated so are the apps you use, which demand ever more CPU resource and battery power. This will be the primary cause of the excessive battery drain and hence extra heat on an older model. Of course there's the fact that eventually a rechargable battery will start behaving crazy the older it gets. They are only supposed to function correctly for 500 recharge cycles, after that all manner of craziness happens.
A temp fix would be to check the firmware is the lastest version which goes someway to correct these issues, but eventually nothing will remove the need for a battery change or new phone i'm afraid. Like most electronics they simply arent build to last.
You could also flash a custom ROM and only have the apps you want but that's a different conversation.
Thanks for the reply ?.
I guess you're right. Its like trying to run a compatible game on an old PC while using the video and cpu on their maximum capacity all the time.
I'll look for a light custom rom. Done that many times to some of my older phones so I think I'll manage to install one. Thanks again for the above
