overheating and freezing - ZTE Axon 7 Questions & Answers

Currently on Stock and there are various instances where my device will either freeze or overheat and turn off. The temperature is about 96 degrees right now where I live and let's say I'm outside for like 15minutes my device will have turned off and refused to turn on unless I cool it down. Is my device a bust? Should I consider changing it?

Sounds extreme, but even in 65F weather my device will overheat and shut down if I'm fast charging + watching video or otherwise moderately using it.

I have temperatures over 30°C here, the phone wouldn't even notice... I played intensive stuff while it was charging (RR3)
Did you unlock the bootloader?/did you do anything to the system?

I realized it was something related to the stock rom. Something was constantly running cause the device to overheat and freeze

I don't have this issue, other than, occasional hiccups but with chrome. When this starts, I wipe cache because my phone tells me it's stored around 500MB of cache in chrome alone at that point. I usually have to do this every few days... It is very annoying...
In your case I would try that first, if it doesn't work, FDR it. It does indeed sound software related. I know saying FDR is really a cookie cutter solution, but it really could solve this issue.

{Q} I am starting to think its my girl

Hey guys Im a EVo user and my girl has an Epic.
Now the next statement is with either running stock or a custom rom
Her phones slows way down and reboot its required, wifi is odd sometimes a reboot to connect, and today her battery became rather hot over 100 F.
Is there anything I can try out on her phone?
Sounds like a specific phone harware issue, i dont get overheats or slow downs, no matter how many apps are running at the same time and even if i charge and use mobile ap all the time, still no overheats here.
Ive Done this on both stock and custom roms and no overheats or slow down..
darn, thankyou for a reply, guess I'll update her ROM and start her off fresh
I don't get slow downs either. I leave my wifi on all day and don't have issues connecting. I only overheated once. Shortly after I got my phone I was downloading stuff left and right, playing graphics heavy games like radio ball, and trying to charge my nearly dead battery all at the same time. When I got the overheat message I figured it was a sign that I needed to turn the phone off and walk away for a little while.
Either the phone has a problem, or your girl does. (which were pretty much your choices to begin with)
Yep no issue at all here usually always on wifi and I'm a heavy user. I get no slow down or anything and I'm on stock rom with bloatware removed.

My phone does slow down after about 2-3 days of uptime. I'm 100% stock, not rooted. Reboot resolves the issues.
After @ 2-3 day uptime the following happens:
1. I've had issues when rotating between home screens where all my widgets & icons disappear, then come back to normal.
2. Also, sometimes my swiping isn't recognized when trying to cycle home screens.
It's difficult to reproduce on demand, thus making my case to Sprint for replacement even more difficult. So I said screw it, just hoping 2.2.1 will resolve the problems whenever its rolled out OTA.

You may be right. I would get a different girlfriend and see if the overheating/rebooting problem continues. If it stops, we know where the problem was. If the problems continue with the new girlfriend, it may be you.

[Q] Phone very slow, hang, unresponsive

Sometimes my phone will get very unresponsive such that any action takes many seconds to show up, and everything is very choppy. Often I see this when I wake up in the morning, but it happens often enough in general. It's so bad that I can't shut it down normally because it would take over 10 min (I've actually never waited to see exactly how long it would take). Thankfully I just found out about the three finger reset (volume up, camera, power), so I shouldn't have to pull the battery anymore, but it's still a problem.
I don't remember this happening before using custom roms. It happens with both DK28 roms I've tried - Bonsai and Viper. I believe it also occurred on the 2.1 Epic Experience, although I'm not sure. I guess I should try flashing to DK28 stock to see if that works, but it's a pain to set up everything each time. I figured I'd ask here to see if anyone else has had this problem and found a way to fix it. Also, I have a feeling this could be related to WiFi being turned on, but can't confirm yet.
My phone was stuttering yesterday.
But that was only after installing smartbench and using theonscreen keyboard.
However, since I've upgraded to dk28, the phone does take (relatively) forever to shutdown.
It'll go black but the bottom lights would still be on and then like a minute or two later it vibrates and actually cuts off

When my phone does this, it reminds me that I like to have SeePU installed. It's pretty useful in pointing out the apps that are hogging CPU and most likely slowing down your phone.
For me it's often Touchdown, and I kill it and things are back to normal.
I have found a few things that are useful. When I need to reboot my phone I use quick boot from the market. Works every time. In between I use fast reboot also from the market. Try them and see how they work.

Thanks for the app suggestions. I like the taskbar icons for SeePU. It's always been useful on my Mac (stats from iStat). Quick Boot makes things easier as well.
Next time my phone hangs, I'll see if some process is taking 100% CPU.
The phone hung again, and it seemed like something was taking 100% CPU, if the taskbar SeePU icon is to be trusted. I wasn't able to figure out what the culprit was though, because the phone pretty much stopped responding. Otherwise I would have loaded Android System Info to check.
can the epic 4g run this lag fix? if not, do we have any other ways to fix the lag?
http://forum.xda-developers.com/showthread.php?t=784691
edit: nvm
So I was able to view Android System Info while my phone was hanging, but it did now show any processes taking 100% CPU, although the total CPU usage was 100%. My guess then is that the Android 2.2 OS is buggy.
However, I did find people who said leaving USB debugging on would fix it, so I'm going to try that.
For reference:

My phone hasn't hung for a while, so apparently enabling USB debugging prevents the hang / lag / crash / 100% CPU. Weird but I'm glad it works
Now the only problem is kswapd0 eating CPU sometimes. I think this is caused by lack of memory, but I'm not sure what I can do about it.

[Q] SGS2 Overheating?

I've been having a few issues with a couple of games freezing and have also had the phone get quite hot, particularly around the camera end. The two games I've had freeze up a lot are Fruit Slice and Pinball Classic, neither are spectacular graphics wise. Basically the games just freeze up and either I'm ejected to the home screen or I have to power off/restart. Occasionally I do get the "Force Close" box, but not very often, this contrary to what I would expect if it were just a normal bug related issue. sometimes it crashes after 5 mins or so, other times straight away. What makes me think it might be overheating is that once it does freeze up, it will do so again almost instantly if I relaunch. The rest of the phone seems okay in operation, I've run a few benchmarks and stress tests, all run okay so far. However (and it is a BIG however), once the phone has got warm, if I go to adjust my screen brightness I am limited to how high I can raise it and receive the following message: "To avoid overheating, maximum brightness has been reduced" (I've attached a screen print below).
Does anybody else get these issues or that message?
Got that "To avoid overheating..." message too while using Navigon Mobile Navigator inside my car (attached to charger).
In some other post I also read about a message like "To avoid overheating, the charging process has been paused", but this depends on the temperature of the battery only (I think).
Regarding the crashing games, that might be a problem of the game. But I had some crashing games, too, but I could not find a relation to the temperature of the phone.
Anyway, it could still be a heat problem.
In my opinion it would had be better for samsung to make the phone some mm thicker to better deal with heat and including a more powerful battery than just claiming to have the thinnest superphone.
Anyway, its still a great device.
Useful to hear it happens on other handsets, in fact I've now found a few threads talking about the issue happening on other models of samsung phone, such as the Infuse.
On the crashing games front, would you mind trying out Fruit Slice for a bit, to see if it hangs on you? If it dosen't crash after 10 mins or so I would think you're okay.
about overheating
i did experience it
when i left the phone in the car it became very hot and i get the same message

I'll try that as soon as I have it back (and if I remember to test), its currently at the repair facility because of a faulty camera.

Cheers, really appreiated. Just to update, I played it again just now, managed 3 games before it froze and kicked me out to the home screen; again no crash dialoge asking force close/wait?! I also checked my temp immediatly after it crashed, using Stability Test V1.5, it reported 31c, which dosen't sound too hot from what I've heard...who knows, cheers agian though!

sorry about the double post
Okay, I've been playing now about 15+ minutes without any problem. The phone doesnt get even hot, just a little bit warm. Using Navigon Navigator it gets a LOT more hotter.
So maybe you should try a factory reset? Or its a faulty phone...
By the way, I had display brightness set to Auto and I'm on german KE7 firmware.

phone temp

I think that the heating up issue has been adressed already, so I was just wondering if anyone can recommend
a temperature app that I can use to measure the heating up of the phone.
Also, which temperature is considered "OK", and from where are we talking about "danger zone",
and what can become damaged if the phone gets into the danger zone often?
I found a great game (might and magic clash of heroes), but with the phone heating up,
I find myself cutting gaming short to let the phone cool down a little.
When I say cuting gaming short, I mean 15 minutes tops, anything beyond that and I can make omlets on the screen.
I also found the game stops being responsive (i.e. I'm unable to enter commands properly),
as if the hot screen is somehow preventing accurate control. Maybe it's just the game, maybe it's the phone.

Yes I did v it... It worked for me...?
it resolved the lag and heating problems but still having problems with google apps connecting through my wifi connection. even if I can basically browse the web using chrome, I cant add a google account in the settings cuz of the issue im having.
Still having battery problems after this. The battery doesn't drain as fast but it takes 3X longer to charge.
didnt solve this that hard reset.. still getting micro freeze lag in games and tablet heats up to 40c playing games like clash of clans and boom beach and this is with 2 cores and 30fps limit set , if i plug in charger it seems stuck, only way is to turn of tablet and turn in cable then it charges normaly... no this is something not right here i never had heat issues or lag in the games i played what a disaster
It even stays at 41c even if i dont play any games, its like the cpu is at 100% for some reason but i did hard reset so wtf is this nonsense ?

When you say "hard reset" do you mean a reboot or a full factory wipe from the settings menu? I factory reset mine and have had no issues except a little stuttering, but it's far less than it was for me before the update. Make sure you're factory resetting from the settings menu and not from a custom recovery... it will erase everything and reinstall the OS from the factory image of the 5.1 update, which a wipe from a custom recovery doesn't do.

Installing a new ROM sometimes does this. I've had similar problems with my phone. Solved by calibrating the battery.
It may take several iterations though.
EDIT: by 'this', I mean heating up and draining of battery mainly.
I did a factory reset yes wiped everything, not just reboot the device sorry but problem is still there and this is from using the tablet over a year never any battery or heat problems.. all started after i updated to 5..1
so why do i have issues then ? it must be faulty update im not the only one having heat and battery problems now.. I feel cheated the update promised increased performance and stability improvements i dont see any of that so far only problems and negative stuff..
and how do u calibrate the battery then ?

There are many versions of essentially the same thing, nothing is guaranteed though, you can google it. Usually it requires root, I guess that's not your case.
So what you have to do is switch off your device and let it charge to 100%. Do not unplug it even then and let it charge for 2-3 hours even after that. Switch on, use it normally. If it's solved then good, if it isn't repeat the process. Like I said, it could take several iterations.
(I calibrated even my laptop's battery the same way in the past. I thought it was gonna die but it worked for another year after that.)
My experience:
A while ago I flashed my phone with unofficial custom cyanogenmod recovery. It worked flawlessly. I used to manually flash the updates as well. This one time, I encountered battery heating up and draining like hell, even if the phone was connected to the charger, battery percentage would go down with each second. Luckily my phone was rooted. I tried calibrating apps from Play Store and it worked. I flashed updates after that as well, but recently, I flashed a new ROM update, and the problem is back. But this time, it's not resolving. I think I've tried every possible way. After a few tries, battery is not heating/draining when using normally, but as soon as I plug it for charging, it gets heated up. (EDIT: it's alright now, without doing anything else than regularly charging and using normally).
Charger is not faulty, I'm sure, plus I've tried a couple of different chargers. ROM is not faulty, if it was everyone would b having the same problem I guess. Also, I re-flashed the previous version, which used to work alright, but the issue remained the same. I'm hoping this would be resolved after a few more tries, or after a new update. As I said, it's not guaranteed, but it works sometimes.
People may tell you to delete the batterystats.bin (this is what calibration apps do, requires root). But a google engineer confirmed that it does essentially nothing as whenever you charge to 100%, the file is automatically reset. http://www.xda-developers.com/google-engineer-debunks-myth-wiping-battery-stats-does-not-improve-battery-life/
Although I'm not having any battery issues, I still liked it better before this update. I think I'm gonna downgrade it, if there's a way.
Sidenote: If you ever decide to flash a custom recovery or OTA update, make sure you have high percentage of battery. Flashing ROMs on low battery can cause issues too. (I don't have any evidence for this, just experience, so I may be wrong.)
battery problem is due to performance setting.........every app uses 100% 4Core max limit of tab.... even playstore,chrome etc like app
If u have back up on TWRP u can run TWRP via fastboot. Then install the SuperSU.zip with recovery and make restore. All works fine and 5.1 is gone.
fix heating and battery drain issue.
I solved lag issue by doing this, hope it helps.
