My S4 started acting weird a couple days ago. It would occasionally self-reboot when I woke the phone by the home button or the power button. During those self-reboots, the AT&T logo seemed to stay longer (probably a couple minutes) than a normal reboot but everything was fine afterwards (could still use the phone for hours without triggering another self-reboot).
The situation went downhill quickly today and now it always gets stuck at the AT&T logo. Press and hold the power button will reboot the phone until the AT&T screen and the only way to turn it off is removing the battery. I can still charge the phone but sometimes instead of showing a charging battery icon, the phone will power on when I press the power button.
I've tried a few tricks (remove SIM and microSD card, pull battery, boot into recovery and wipe cache partition) but none worked. In the beginning, I did manage to boot past the AT&T logo a few times (self-reboot with home/power button still persisted) but no luck since this afternoon.
Since I haven't made any changes to the phone in the 2-3 weeks before the above problem occurred, can this be hardware-related (like a bad battery)?
And at this point, is it still possible to unbrick the phone without wiping the data?
Thanks for helping!

It could be battery. However, most reboot caused by bad battery occurs when you run the apps not in the idle condition.
It could also be conflict in the rom (OS).
I do not think there a way to unbrick the phone without wiping the data (factory reset) unless the unbrick was caused by the battery failure.

Thanks! I'll get a new battery and see if it can work miracles.

I was running this custom rom beautifully fine for over a year now since I got my phone.
Recently I've had so many problems. My phone just randomly shutdowns down and it's very hard to get it to boot up again. If i hold down the power nothing happens or I just get 1 vibration. Taking the battery in and out doesn't do anything. I left it for 5 minutes out and put battery back in it just vibrates a little (samsung logo apepars for a second) and nothing happens, even when I hold power button. Can't get into download mode either.
I tried 2 different batteries too.
Really not sure what to do. I tried a factory reset a whilst back and i thought everything was okay but now it just won't even boot up.
Whenevr it does decide to turn on it just dies after a random period of time.

emm.. your description is confusing a bit... does your phone boots, or not?
If not, call the Samsung service centre (if I'm right, one is in Milton Keynes even, if not, there is another one in Derby).
If it does: try factory wipe and pure stock reflash.
--- This may belong in the Xposed forum, I am uncertain. ---
Hello. Please forgive my ignorance regarding the technical aspects of methods discussed on these forums.
I have a Samsung Galaxy S4 GT-I9505 supplied by Vodafone Australia. This was received today as a replacement for a screen issue I had with my previous S4. On the previous S4, I had rooted using a Saferoot method as read about on this forum. Later I had installed Xposed to use Keepchat and everything was fine. Today I have rooted this replacement phone successfully using the same method, and then moved to install Xposed. The Xposed application required an update, the very first option in the app was red and suggested an update or a reboot, and the reboot did nothing, so I pressed update. The phone turned off but didn't restart. I tried the usual button presses and battery pulls and finally a simple power up using the standard power button started the phone up. It got as far as the lock screen I believe, before shutting down again. It is now unresponsive. It wont turn on, enter the boot menu (multi button holding method) or charge. I believe the battery is quite low at this point, and unable to charge, causing me some consternation. It has now been over 30 minutes with no response.
If anyone could provide a resolution to this issue, I would be extremely thankful.
Regards,
CaleS

Hello again.
I have an update on my situation.
I left the phone on charge and it eventually turned on by itself. I played around with it for a while and it seemed OK. Eventually it turned off again. I had to pull the battery to get it to turn back on. After starting up again, getting to the lockscreen, it turned off again. This process repeated many times, until I got frustrated.
The next day I thought I'd try a factory reset via volume up + power, and the device managed to stay on long enough for this to complete. After the phone reset, I used it for a while and again it turned off. The same cycle continued.
Perhaps the phone is naturally faulty, despite my rooting attempt, as it was a refurbished model. I am quite happy to return it for another replacement under warranty, however I may not be able to do it as the device is rooted. I would gladly remove the root using stock firmware and Odin, however the phone resets after a few seconds of entering download mode.
Any advice?
Thanks.
Sounds to me you have a faulty power button. It's somehow stuck that's why it even reboots in download mode. It's a common problem for the S4. Try to wedge it or replace it.
if it is refurbished model it might as well be dead battery.
battery sensor detects "low battery" state and shutdown phone saying battery 0% - to protect battery against fully depleted state (damaging to max capacity or even impossible to charge at some point)
if you power it on again it will boot and say it has like 1% left and you will be able to use it for few more moments, but doing so will degrade your battery.
powering it on, going to lock screen for it to shutdown on its own again sounds like weak power source
imagine above scenario happening several times (previous owner of the phone kept "reviving" it after shutdown due to battery 0%)
that would resulted in battery able to hold only fraction of its standard power - allowing you to just boot your phone before it shuts down.
I had similar situation with my laptop battery (this one was on AC all the time) - battery was so damaged that laptop was shutting down at windows login screen - if booted on battery alone.
When booted on AC and unplugged it said 100% battery, that went down to 0% in a matter of around 2 minutes, when laptop shuts down.
Dont know if any one is facing the same problem.
Installed Lollipop in my S4 over the air, 2 weeks ago.
A week back, my phone entered into BootLoop mode. Phone gets re-started. I can see Samsung logo and it gets restarted again. I tried removing the battery and kept it back. Started working fine then.
Since today after noon, my S4 is in complete boot loop. Tried removing the battery and kept it back. Yet it is in bootloop.
Unable to enter into Developer options also. Please help
I hit the Power Button against a Flat Surface. It Vibrates and shows the Samsung Logo. But then it turns off.
Is the battery empty maybe?
My guess is that your power button is faulty. Either try to wiggle it lose or replace it. It's really cheap
If it reboots in download mode and/or your recovery then it's your power button.

I tried it again with wiggling and hitting it a little bit.
it turns on automatically and then it turns off after some second again
I've looked online, especially on here, for solutions to my problem but they all seem to assume that I can access fastboot. Here is my specific problem:
I was using my phone and suddenly the screen went black. It rebooted once into the OS but immediately restarted and has been stuck in bootloop for 4.5hrs thus far. I have tried to wipe cache, enter fastboot, power down the phone but nothing worked and it kept looping. Even when I powered off. It's like the power button signal is malfunctioning because it doesn't always reboot at the same exact point in the boot cycle.
My phone is stock, no custom anything, and is encrypted. My only thought right now is to let the battery drain fully and try to boot again after that. I have not tried to enter fastboot while connected to a PC, but I have tried to do it just on the phone.
I have not been home yet so I do not have access to a PC I can actually do things with at the moment. Any help is much appreciated. Thanks!
EDIT: I am home now. Going on 6hrs of looping and nothing has changed.
EDIT 2: The battery was drained. It starts to charge but instantly tries to enter the boot loop again so the battery never gets enough charge to do anything; thus, I can do nothing to save the phone, I don't think.
If its some malfunction with power button, try to abuse the button gently. I used to do that with my Nexus 5 when its power button gets stuck inside causing bootloops.

The button itself is fine, it works as it should and is not pressed down; however, there might be some sort of internal problem causing the phone to think that it's being pressed.
Good day XDA,
My phone went on a real havoc starting yesterday when it kept on rebooting in the "Samsung Galaxy S5 powered by Android" logo. It doesn't go past it without having the phone plugged into into a power source, either USB, powerbank or wall charger. After charging it 'til it goes full, it only takes few minutes to few hours before it goes to the same cycle again - and I have to plug it in again in order to use it properly.
What could be the problem? Your immediate response is greatly appreciated. Thanks everyone!
hi , i find when i experience this issue is when play store updates theme that i have in use at time , soon as i reboot i get bootloops ...i fix mine by pressing and holding vol down menu and power for as long as it takes for bootloader then press them same keys again but release before bootloader so that your phone boots as normal hope this helps
I know this is the combination for force reboot but sadly, that doesn't help. Thanks for the idea, though.
Tried clearing caches from recovery?
Battery still good?
I think the battery might be the problem. When I tried charging it, I went back and it was on 92% then few seconds later, it jumped to 100%. I tried booting it but with no luck, so I pulled the battery and upon putting it back, it dropped to 50%. I pulled and put it back again and it went to 84%. I'm thinking it might be the battery. I cannot boot into system or TWRP, only on Odin mode but I need to save the files saved on my internal storage as it has photos I haven't backed up yet.
