[Q] Phone won't turn on

Last night I had dropped my phone from about a foot on a sitting-swing and it hit the ground. I have the black case from the sprint store on it. After that I attempted to turn it on and it just got stuck on Samsung loading screen with the genocide 2.0 logo below it, it then proceeded to be stuck there and eventually rebooted, this never seemed to end. When I attempted to plug it in to charge it the battery charging icon appeared but just has the loading symbol inside of it frozen, after many battery pulls and attempted clockwork-recovery boots failing I decided to go to bed. When I awake I went and tried to turn on my phone which immediately booted up into clockwork recover, fearing for my phones safety I backed everything up on it and then rebooted it. It seemed to work fine! It came on flawlessly and worked well. Throughout the day the battery seemed to drain extremely fast and then eventually died, having just gotten home I have found that the same thing is happening and it won't even charge.

Re flash the ROM then flash journaling on zip right after you flash the ROM then re boot & download you're apps fresh cuz you're data might be corrupted! Hit the thanks button if I've helped in any way! ;-)

I flashed back to stock rom to see if it would turn on, same thing happens, and I don't know if this is significant or not but when my phone boots up the buttons light up, then turn off, then back on again and stay on until the phone reboots itself or the battery is pulled.
EDIT: I have a strong feeling it's my physical battery that is causing the issues because it was working completely fine earlier yesterday.

Try booting in safe mode by holding power and the physical menu button until the phone gets to the lockscreen... Im curious to see if it helps because safe mode might help us get out of soft bricks? I wanna test this theory...

No it does not work, just get stuck at the Samsung loading screen. I don't honestly believe this is a software brick either because of the way it's acting, as I said in my above post I believe it's the physical battery and will probably be going to get it replaced soon

Power button not working suddenly

Last night while using my phone it suddenly rebooted itself, and when it came back on the power button no longer worked. I could use the volume buttons to wake the phone, but even that stopped working after a while. I went to sleep and let it charge overnight, and when I woke up, all was working normally. Its been normal all day until a few min ago, the phone rebooted and now once again the power button wont work. Anyone had this problem? Any suggestions, besides take it to Sprint, which I will do if it continues?

Well I took it to a Sprint store and the tech said the button is physically fine, and worked when doing a hard reset but once the phone came back on it went back to not working again. So he thinks it's a software issue and ordered me a replacement. And my E4GT is completely stock, never rooted. Just decided to let u guys know just in case anyone else happens to have the same problem.

If it is a software problem which it sounds like to me I would root that thing and throw a rom on there and see if that works. Preferably Phantom Hackers Blazer rom 4.1 Pure win!

I have this problem right now it came out of no where and was working fine till now. When I flashed a new rom my power button still wont work.

My power button isn't working either. My phone randomly reboots and isn't usable. My buddy gave me his old Samsung Moment to use It's like I'm back in the stone age with this thing. No insurance on my E4GT either FML.

It's still under a year old isn't it? Take it in and spend the $35.00 for Sprint to troubleshoot and replace it under warranty.

I was having this issue with my e4gt so i tried to flash a new ROM onto it. That didn't work, so I restored it to factory using this one-click Odin method http://forum.xda-developers.com/showthread.php?t=1721229
Since the power button didn't function for me I had to use Terminal Emulator to reboot into download mode. Restoring to factory seemed to have restored the power button. I had a few phantom reboots but the phone has been running for 13 hours right now. Seems to be fixed. I plan on waiting a week before rooting it again, in case i decide to take it to Sprint.
Hope this helps

HELP!!

did that fix the problem? im on the universe 2.1 rom and for some odd reason while i left my phone on the table it all of a sudden rebooted and my power button wasnt working either? well can you let me know if that fixed the problem for you? I cant use the power button at all and whenever i take out my battery and put it back in, it automatically starts my phone up right when i put the battery in. but please let me know if urs is fine now. thanks
sh*t, nevermind i just tried to do the odin one click and it restored my factory settings and everything but the power button still doesnt work... =( damnit!!
ok nevermind that too... sorry for blowing up your post but just wanted to inform that i just applied more pressure to the power button and held it there for a few seconds and then let go and all of a sudden the power button started working again... i was reading through other posts about this and they said that it happens often with this phone... but this is how i ended up fixing mine if the odin one click doesnt work...

For those of you who don't have insurance, or those who this option is cheaper, they can replace the power button for $35. I didn't look if it includes shipping. If it were me, and I had a little more money, I'd get the power button and usb port changed to new ones at the same time. The port might go out eventually and it saves you the time and hassle of sending it in again. Hell, $75 is still cheaper than paying the $100 deductible if sprint tries to make you pay that for a refurb.

My phone started rebooting constantly since last week. I went back to the ICS 4.03 ROM and it was ok for a few days and then it starting rebooting again yesterday. Today once the phone screen goes off it comes back on and when i press the power button to turn the screen off, it restarts. The only time it acts normal is when it is charging. I do have insurance so I'm thinking about removing the superuser app and taking it to sprint. My question is will they try fixing it before giving me a replacement & will it be refurbished? I'm at wit's end with this phone. I loved this phone until last week

If you can go back to gingerbread(clean install) you should give that a try before you go back to sprint and find your self back at square one after flashing ics, replacement phone may have gb installed. Run some stock rooted gb for a while and see what happens.

I did that & it was ok for a few days then it started again...today it worked better than most days but the power button still wont turn the screen off if I press it

I have the same symptoms with mine, which started 2 days ago while out of town. The only difference being my power button goes from hyper-sensitive in that if I even brush my finger by it it closes the screen to not registering anything no matter how hard I click. Any way to tell via logs, etc if this is hardware or software? Phone is unuseable with the constant reboots...

Update
Had been running Calks 3.0 before the power button issue, so decided to start over to see if it helped:
1) Ran Calks Format All
2) Reflashed 3.0
3) Ran his Bare ROM Converter
Result: Problem disappeared, so far. Will report back if anything changes, but worth a complete reformat and reflash try since I am out of warranty as an original adopter 9/16/11.

this just happened to me while running cm10 alphas. power button wouldn't work at all and occasionally it would just reboot.
i full wiped and installed one of agat's mods. we'll see what happens.

Everything was perfect since the re-flash UNTIL I took a flight and the same problem with the power button started again. Whats funny is the last time the same thing happened. Chain of events:
1) Two weeks ago phone was perfect running Calks 3.0 GB ROM and had been for the last 3-4 months. Stock rooted for 5 months prior.
2) Went to airport, phone went thru security scanner and boarded plane.
3) Prior to departing, checked phone and noticed the power button didnt turn screen back on.
4) Pulled battery/ put back in, and the phone rebooted without me pressing the power button, which it never had previously.
5) Phone boots back up to lockscreen, and notice the power button is hyper-sensitive (If I lightly brush my finger against it, the "Power Off, Reset, Recovery...." screen pops up. Its like the power button has become a capacitance button like the four at the bottom face of the phone.
6) Try using, and it randomly reboots, even completely avoiding the right edge of the phone (power button side)
7) If phone screen is allowed to go dark, power button wont awaken it, but volume buttons sometimes will...Also, plugging/unplugging into charger will awaken screen. If I reboot the phone with it charging, it turns off and goes into charging mode with the green battery bar graph.
8) Struggled with the phone screen turning on/off, randomly rebooting with/without touching, turning, using, etc.
9) Arrived home and after many attempts, booted into Rogue Recovery, wiped/all format/reflashed Calks 3.0/Bare ROM converter and phone was just as it was before....Until 5 days later when I boarded another flight.......Why?

[Q] Powers off, powers on, powers off... Help!

Late last night while playing games on my phone it froze and I had to hold in the power button to reset it.
When it powered back on, it froze almost immediately, powered down after a couple of minutes, turned back on and repeated the cycle. As I was already in bed I plugged the phone in and assumed it would fix itself and be fine in the morning.
Except it isn't. This morning the phone is very warm and is still poering on, freezing and powering off. If I do a battery pull and turn it on myself, it does the same thing so right now I've just got it turned off.
I noticed when it turned on that Google Wallet icon would appear in the status bar and it was at this point that the phone froze. I was able to go into Rom Toolbox before the Wallet icon appeared and managed to disable Google Wallet at startup, but this had no effect. I went into recovery and cleared cache and dalvik, this had no effect.
What may be causing this power cycling? I haven't installed any new apps in days, I haven't downloaded anything, and I turn my phone off and on every morning and it's never done this before.
If it helps I'm on Freeza's deodexed stock unrooted MD4.

Check to see if the power button is stuck

I think it's fine. It can certainly be pressed with no problem and it seems to release itself as normal. I am going to try restoring a backup from last week and seeing if it still does it after that.

I would recommend maybe doing a FULL Wipe, and Flash. Might be a Bad Flash.

Sounds like the sudden death syndrome which is the power button failure. The physical button looks and feels fine its the internal contact which meses up. Try tapping on it or blowing some compressed air into the power button area. My understanding is they repair this as its a known problem.

[Q] Not quite sudden death - but still a major problem

So I recently installed CM 10.1.2 on my S3, and everything worked perfectly for a few days. Yesterday though, my phone started acting strangely (lag when turning screen off, registering phantom input, etc) and began rebooting every few minutes. At some point, it ran out of battery - and now I can no longer boot past the CM loading wheel screen.
I can't boot to recovery, and I don't think my phone is taking charge (from my computer or a wall outlet), and the farthest I can get is the loading wheel - sometimes it only gets as far as displaying the Samsung logo, or the Galaxy S3 screen with the android dude at the bottom.
I'm still covered under warranty, and would love to take it to the store for a replacement (I've had battery issues prior to this), but the fact that it can get to the CM loading wheel means that they might figure out that I've rooted and whatnot. But I can't get to recovery to flash a stock image, so...what can I do?

Your best shot is to either borrow someone's S3 battery or buy a battery pack. Use that to restore your phone back to stock (unroot) and then you can go to the store for replacement.

So turns out battery isn't the issue, I used a wall charger to get it to full charge. I can get it to the download mode confirmation screen, and can press volume up to confirm - but my phone reboots soon after that.
Recovery isn't really possible either, I can see the blue text in the upper right but my phone reboots after that as well.
My phone will often show an empty battery icon with a little refresh icon in the middle; does this indicate that it doesn't see the battery as charged (even though it is)?

Yeah I've been doing some research into the issue...
I've noticed that my phone automatically boots when I put the battery in, and that it'll do a quick vibrate when plugged in to a power source (outlet or computer) but won't turn on.
Apparently the phone isn't supposed to boot automatically when the battery is put in, and this could be the source of the random reboots - I think if I can get the rebooting under control, I'll be able to get into download mode and fix it all. But I'm not sure how to do that. Maybe the power button has gone bad, as it also doesn't usually respond when I try to use it to turn on.
If there is a problem with the power button, does anyone have any ideas on how to fix it?

Mine does the exact same thing where I have to pull the battery and when I put it back in it automatically starts up and when I go to download or recovery it turns off before I can do anything

Sounds like power button issue.
I was having the same issues (random reboots, boot loop, powering on when battery put in, reboots in download mode and recovery)
This is not an easy fix. I ended up pulling the power button out and just setting my screen to time out after 15 seconds. Sucks but it works now.
If I ever need to turn off or hard reboot, I stick a pin in the power button hole and push down on the button.

The power button is a common issue for these phones.

[q] screen is glitchy after dropping!

Two days ago, my T-Mobile Samsung Galaxy S3 dropped out of my coat pocket as i was running for the bus. I picked it up and saw the screen was cracked along the top left and bottom left hand side. Everything was working for the past two days and i figured i'll just wait till Christmas to get a new phone. This morning i took my phone off the charger and turned it on. The Samsung logo flashed, and then the boot animation for Slimrom (the custom rom i'm currently running on) flashed for about a second but then the screen went black. I did a battery pull but the weird thing is whenever i put my battery back in, even without touching the power button, it boots up by itself but then the screen goes black again. I can access TWRP and download mode but they both go black after a few seconds as well. I was able to successfully turn on my phone and have it fully function for about 15 minutes after putting it back on the charger, but it quickly blacked out again. It also keeps randomly booting up by itself which is weird. Im guessing this is a problem with the screen itself, but could it be a software issue because the device keeps booting up by itself? If it is the screen, will i have to buy a new one or is it not worth it? I've also tried using a different battery and i have the same issue so it can't be that. Any help is appreciated!

Sounds like an issue with the power button, it probably got stuck somehow either when you dropped it, or after you dropped it. Do a simple search for power button and you will find ways to fix it!

Holy crap i didn't even think of that! It makes total sense since every time i even tap my power button, even for just a second, it turns on. I've read around that clearing the cache or a factory reset could work. Is this true?

Unlikely, unless it's a software issue but it's always a possibility. Slam the phone against something to try to get the power button back into place, or open it up and try to see if you can fix it yourself, or replace it

The problem seems to be gone. I haven't had any issues for two days now. All i did was press the power button really hard multiple times. Thanks for you help man!
