For about 2 months since I have owned this phone it has given me nothing but crap. I always kept my G1 in my pocket and I always dropped it, even had it in water 3 times! (never had any problems) The G2 however if I kept it in my pocket, dropped it, or open/closed the keyboard repeatedly the phone would shutoff! Very Very disappointed at first. I missed many calls and text messages.
So How come NOW I can drop it, open/close the keyboard repeatedly, and keep it in my pocket without it shutting off?
I did a little investigating of the battery and contact points on this phone, it turns out that there is room for play with my battery. SO every so often the contacts would lose connection with the battery!
TO fix this I put a small piece of folded paper along the top edge of the battery opposite of the contact point to the phone, it made a more secure and snug fit to the contact points.
The battery does get Hot so I do not recommend this as a permanent fix as it is now a small fire hazard.
BUT, to this day I have had ZERO problems.
I am sooooo now with my G2 any questions or other comments please leave them below.
CYANOGENMOD 7 RC1
Class 10 4gb microSd
1500MAH battery
Hard rubberized black graphic case
Talk about going backward! I remember the old nokia 5160s that everyone and their brother had folded up paper in the batteries about 10 years ago! LOL

Meh... I don't think anyone else has this problem. If they did then they probably exchanged it.

I have this problem.
I can't exchange it because I bought the phone on ebay.
If you search through the threads and on google, quite a few people experience this random freeze / shutdown where you have to do a battery pull.
I've tried flashing different roms, using only basic apps etc...
I don't think it's software related anymore, and if it is, it's too hard to diagnose. Many suggestions have been made, micro sd card slot, battery connections, software, weird app, different rom... I haven't tried removing SD card yet and my battery connection seems ok, it's pretty tight in there...
Don't know what the problem is and I wish someone could figure it out as it's frustrating to drop too much $$$ on a phone and have it act this way.
Random Reboots
I have a similar problem with my G2. It randomly reboots when its siting stationary on my desk or in my car.
This problem is made stranger though because it NEVER does this while I'm using it!! If I have it playing Pandora or Youtube - no reboots. But, like clockwork, if turn off the screen and set it on my desk, reboot... never fails... it will reboot 2 or 3 times then seems to be ok for a little while. Very annoying because I can't make or receive calls while its doing this.
Like others I've read plenty of posts on this but no working fix I can find. Some people say they returned their phone 2 or 3 times and still have the same issue. Some people say its related to signal strength but it does this will full bars or no bars.
I've tried custom Roms: CM6.1.1, CM7-RC1, & Virtuous 1.0.1 and the problem remains.
Does anyone know how to fix this? This is the only negative about an otherwise HOT little phone.
At least yours reboots! A lot of others just freeze (like mine)! And then you don't even know it.
I'm trying out another theory... Installed CM6 a few days ago. Had the same problem.
But I just started OC using CPU Tuner and the stock CM6 Kernel., the lowest option I have for clock speed is 700 something for some reason, so I just used that. So far, 36h, hasn't done it. I THINK, it might be related to the phone not getting enough juice for some odd reason - even on stock, so when you OC it and set a higher clock speed for idle, it might help. NOT sure yet but testing. Will post up if it "fixes" the problem for me.
My G2 was randomly shutting off a lot, usually right after I stuck it in my pocket. The solution? I exchanged it. The new one never does that XD
Possible fix for random reboot
I think I may have found a working fix for my random reboots. Credit goes to the OP.
I installed the Pershoot kernel and since then I haven't had a reboot and up until now it has rebooted like clockwork.
I'll see how it goes.
I had this problem while using the Red ChiChi/EVO batteries, but I believe my problem to be with the back cover. I might have dropped it and the cover got slightly tweaked, or perhaps it was the chichi battery, as it wasn't exactly a perfect fit. If a certain spot on it gets touched or pushed in, the battery loses contact with the pins and kills the phone. I have to pull the battery and let it set for a minute b4 putting it back in and powering up.
I used the same method, with a piece of folded paper on top for a while.
Perhaps its a different problem than the OP, but this only happened with my ChiChi batteries. With stock battery, it always seemed to be a good enough fit, and the corners kept it in place.
I ended up buying an extra stock battery for around $20, and now I carry 2 Stock batteries at all times.
Solution finally?!
I think I found the solution for my phone:
set OC profiles so the phone doesn't go below a certain mhz threshold.
On CM6 stock with CPU Tuner, it defaults to 700mhz lowest. Did not notice any increase in battery drain.
Uptime - 70 hours. Finally fixed!
//UPDATE: I did experience a freeze around the 100 hour mark, but so far that's the only one in the last week or so. In any case, it's doing MUCH better than before...
//OK I lied it still does it but so far just once or twice a week. Better than once a day.
So far there are apparently three problems/solutions:
- Micro SD slot loose connection / improper close - Check micro SD card slot
- Idle voltage too low, freezes phone / use OC kernel and set screen off speed higher
- Bad battery connection / manually fix
After many tries and diagnosing I think one issue is that on stock settings, the idle / screen off profile is set too low, which can freeze the phone (although I did have it freeze once while I was actively texting... not sure why). But 99% of the time it happened with the screen off. Hopefully it doesn't happen again, will keep phone on to see, but I don't remember it going more than 48h without freezing lately.
I have tried the following which did NOT fix the issue for me:
Micro SD check
Uninstall programs (skype, launcher pro, various others)
Revert to "stock"
CM6 "stock"
Checked Battery
Used stock battery / China battery
All those solutions still led to the random freeze / battery pull situation, but could potentially work for you.
2 G2's did the same thing. T-Mobile states known problem. After 14-hour shut down pulled mSDHC card and Sim and replaced battery which was drained in the off-state.
Solved problem and bought a Nokia N8.
Customer Service at T-Mobile and HTC is totally unconnected and unresponsive. Their answer wait for the FOTA.
Hope they don't send it to my Symbian ^3 jewel!
Was Shutting down multiple times a day - FIXED!
Hey Guys,
I've purchased my G2 from ebay so was not able to return it. So I've been trying to fix this problem for ever.
I have not found anything that works until now (knock on wood).
I installed the Cyanogenmod (cm_vision_full-32.zip) and updated my older CM version. The phone has not shutdown once in 4 days, which is a first.
Note: my GPS does not work with this version. I'm about to try a clean wipe to see if it will activate. I'm guessing however that the shutdown issue is 100% tied to the GPS so if I'm successful the problem will return. If a wipe does not work I'll try new radios.
I'll update any progress.

Caveat emptor.
I know. Live in Canada and only way to get the phone.
Me too, although my phone is at uptime: 211 hours right now
CM6 with cpu tuner with the settings posted above... basically make sure it never underclocks below 700 mhz.
I got nexus 4, and problem is that now and then it shuts down itself... Battery is charging ok, but after working few minutes or hours (no specific time) it just shuts down (idle or working)...
Phone is not rooted, I tried factory reset, and that didn't help either...
Currently it is on 5.0.1, I got it with this version of software so I don't know did this happen earlier on 5.0 or 4.4...
I wanted to do complete root but i'm afraid that it would shutdown itself during the process..
Does anyone knows what can be the problem??
Have you tried flashing the 5.0.1 factory image through fastboot?
Even I am facing the same problem. But for me it does not show shutting down also. It just blanks out at around 40% battery.
Had the exact same problem with my phone until I rooted the phone and changed to a non-stock rom and have not had the problem since.
Hi guys don't know if this helps because mine is slightly different. Mine is reboot itself.
My suspicion is on ram, maybe the device is out ram and then reboot itself, maybe this goes the same to shut down idk (please correct me if I'm wrong). Recently I've put gravity box and I can see how much ram left when I tap the application switcher, it was mind blowing for me. I often find that when you open several application the number of ram available can reach below 500mb (especially chrome tabs, it do have a lot of ram to use) I mean it's a 2 gb ram device wow. Every few days I've checked that when the idle ram is over a gig I do reboot manually. That way my problem of random reboot vanished. Good luck

Screen will not wake from sleep
The device will randomly not wake from a sleep state, and is happening more frequently. I've read that it's possibly linked to a motherboard issue. I have root, TWRP, Xposed. Will flashing a different kernel possibly resolve the issue?
I bought an N4 from eBay and it worked perfectly for months on stock rooted Lollipop. Then it suddenly started to randomly shut down - not reboot, just a sudden buzz and "Power off". I've tried Marshmallow, Chroma, and now Cyanogenmod latest dailies. Plus a new battery (an eBay special, contacts didn't align with screws, but since another suggested fix was to leave the connection screwless that's fine - it seems to hold a charge and works fine).
So my question is - even though the power button seems to be clicky and ok, is it worth trying a new one? I know that it's mainly suggested for random reboots, but maybe it's related?
Or any other bright suggestions? Any help much appreciated.
I bought a new power & volume button and the same "power off" still happens - sometimes immediately on boot, sometimes after a period when it seems to be going ok..
Anyone have any ideas at all which hardware may be responsible? I doubt it's software, since the same happens on all ROMs, rooted or not.
I had the same issue until I reformatted all partitions and installed stock 5.1.1 Now reboots are gone. Looks like my issue was software related. The only change from stock was stability mode from Root Booster

Thanks, Hjicons. I wish I were so lucky...
As I said, different ROMS, root/no root, make no difference. It occasionally runs for a day or so, but as soon as I reboot it's back to immediate "power off".
On the plus side, it's *astonishingly* strong. I treat all my phones with kid gloves - always in a completely empty pocket, no keys or coins, in a plastic bag if there's the slightest threat of rain (even my water-resistant Nexus 6), I set them down gently on surfaces, yadda yadda yadda...
So in frustration, hoping to jar whatever component into proper life, I've banged it hard, very hard, on a mousemat, all four corners, no difference. And last night in a fury of annoyance, to stop myself pointlessly wasting time trying to fix the damn thing, I tried to smash the front glass with a heavy torch and the handle of a big screwdriver, hard enough to bring my wife in from another room to find out what the banging was. Not a scratch, not a crack. Gorilla glass is as strong as they claim it is.
But still not working...
People are complaining that they are facing lag,heating issue,battery draining........in Lollipop v5.1
Here is the solution........
1st- Before Upgrading to v5.1 do wipe and factory reset
2nd-take out your SD card before updating to v5.1
3rd-Again do hard reset after installing v5.1
4th-Done
Please Do hit thanks button if I helped you
Lollipop v5.1 Review by me
Antutu Score increased to Approx 40K
Games like Real Racing 3,Asphalt 8,Nova 3 doesn't lag anymore like kitkat do....(kitkat is very bad update for TN7)
Can't install benchmark tools from play store.
Browsing in Chrome is also improved
Battery performance increased by 15-20%
Everything is buttery Smooth...
Performance mode is hide by nvidia. Don't know why.(Download Activity launcher then select all activities then settings->setting>nvcontrolpanel)
Graphics performance increased a bit.
Music is Same.
Have a Nice Day Sir\Mam.....
Enjoy your LoLLipop ��
is this confirmed 100% that hard reset solves all heat and performance issues if i didnt hard reset before install this update ?

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.
Hi everyone,
So I have a really really strange issue with my phone lately and that is: I get a lot of graphical corruption and random app crashes (any app, including system apps like the Samsung or Google ones), I did in the past do some overclocking but that was way more than 6 months ago and this issue just popped up about 1 month ago and my battery life is now also really short and the phone can show 40% and shut down or show 20% and shut down and then when I plug it in I get the battery charger indicator with 50%+ battery left.
Now here's an even weirder thing: that is not specific to any ROM and happens on more than one, any TW 5.1.1 ROM I try and even on CM13.
I do use multi-boot but I did test the ROMs even without a multiboot environment and those things still happen.
So I was thinking that it might be that my battery is dead (although apps say it's healthy) as I've seen phones doing that when the battery is close to dead but since I can't really purchase a new battery in my country I would like to ask if someone has an opinion on this?
Could this be a hardware defect or something broken in my "hidden" Samsung-specific partitions or is it just the battery, has anyone else encountered this?
I really would like to know how big of a chance it is that my phone is somewhat of a brick before wasting a lot of money to buy a new battery from an other country.
As you can see most of the photos I took have either missing letters or strangely colored letters but that's because that's the graphical glitches I get most, the worse ones have big parts or even half of the screen totally black, UI elements extended awkwardly with gray outlines, strange colors on-screen and missing whole UI elements.
Sorry for the potato quality....took the photos with my Redmi Note 2 with CM12.1 instead of MIUI7 cause I am too sleepy to wait for it to reboot into the other ROM (and I think I wiped the whole cache+dalvik on my last CM update so the boot would take a long time since it would need to do the whole optimization for MIUI7 as well).
Also a photo of Settings crashing, all I did was just open it, saw the settings list and after a second crash.
NOTE: I am on a 100% clean install right now (wiped EVERYTHING including internal storage) and I barely even managed to get past the setup wizard since it kept crashing.
Thanks for any help/opinions/ideas.
No one knows anything?
How can I get it

New battery and did a full odin reflash (with SEA pit file), even updated to 6.0, bugs still here but way less frequent, crashes not here anymore after update to 6.0 but still here before even with a 5.1.1 reflash and clean install, seems like the phone is as good as gone, will try to send it to warranty to see what happens but don't expect much since "Knox Warranty Void=1".
Lesson learned: if such bugs start popping up for any of you guys even if the battery is not in a good state you'd end up better just buying a new phone since your note 4 is quite surely done and gone.
So in the past two weeks I have been experiencing random reboots or shutdowns of my phone. It also seems to have become more frequently. When the phone is off I need to press the power button really long, like 5+ seconds, to get it to start. Does anyone have any idea what might cause these problems or how to narrow it down?
Some more info:
- still on a really old CM13 version (27.06.) / TWRP Hybrid from that time
- haven't flashed any new ROM or modem recently / basically everything is as it was, when it was running without issues
- tried wiping cache/dalvik to no success
Thanks!
Edit:
Flashed cosmicOS. Same issues...
So I found this (put http in front) forums.androidcentral.com/ambassador-guides-tips-how-s/479461-guide-my-battery-shot.html (am not allowed to post links)
And it says: "A battery that's throwing dendrites is one you should replace, even if it's a week old. (There are professors of chemistry and physics all over the world working on why this happens and ways to prevent it. The biggest problem is in early failures of lithium batteries in hybrid and electric cars - 2 grand down the tubes for the manufacturer when that happens to a single cell.) That's why you should look at the second page of the battery stats for a "fall off the cliff" voltage just before the phone shut off or rebooted. A dendrite causes a short. If it's thin and the short burns out almost immediately (microseconds), the phone will reboot. If the short lasts tenths of a second or more the phone shuts off. Either one shows the typical drop to zero in zero time of a dendrite."
Kinda sounds exactly like my problem... So, how do I log the voltages right before the reboot/shut off?
I was going thru the same dam thing and what I did was downgraded and followed some instructions so I mean I lost everything but know is good just get a stock ROM and do what ever they say to do .
