[Galaxy S 4 Q&A, Help & Troubleshooting] leijonasisu:
Hey guys..

I've owned all the Samsung Galaxy phones from the S+ right up to the S4 and I've flashed firmwares over all of them with generally no problems at all.

But lately I have a constant issue that has been plaguing my Galaxy S 4 (i9505) phone since I flashed the 4.3 i9505G (GE Edition) ROM over my phone.. (have since moved to OMEGA v12)

The phone just randomly reboots whenever it seems to feel like it.

It could be whilst taking a picture, it could be whilst using google maps, it could be whilst installing an app from the app store or just scrolling across the screen. It's basically rebooted through anything and everything and I've tried pinning it down to something but every time I think that I've got it sorted out. It crashes again whilst doing something else.

1 thing however has got me stumped. The phone has

NEVER

crashed whilst plugged in. If I keep the phone plugged in, it's never ever just rebooted on its own for me. Which got me thinking that it could be a faulty battery or some sort of voltage issue.

Coming from the 4.3 GE Edition ROM there are other people experiencing random reboots. But now I've just flashed over OMEGA v12 and right after flashing (I did a full wipe of course first) the phone rebooted whilst typing in my Wifi access key. After the reboot I was able to set my phone up and I did a reboot myself, then I went to the app store to add an account and the phone crashed AGAIN.

I'm totally over this issue with my phone. I paid a small fortune for it and I cannot rely on it at all. So I absolutely need it to work. I've had issues on 4.3 GE getting Mobile Data to work. I've had issues with it crashing and I'm just done with all of this.

Do you think that my phone is already broken? (It's barely 3 months old) Do I need to get it replaced under warranty? Can I even get it replaced under warranty, is there a way to even get my warranty back or reset the flash counter etc?

I'm just so confused guys :( I thought maybe it was my battery, and that my battery was faulty because I had battery percentages dropping and jumping around like mad. For example 15% battery left would actually have the phone turn off... and reboot at 0%. Then the light wouldn't go green for 'Fully charged' and the phone would sit on 99% or 100% but still not say 'charged'. In addition I could swear I had lost more than 10% of my charge in the blink of an eye etc.

I just bought 2 new batteries but they will take a week to get here.. and if the phone is still rebooting (and it isn't a voltage/cut out issue with the battery) then should I assume it's a hardware issue and that the phone needs replacing? Or could it just be a bad flash or something? The phone has at least a 2 year warranty. I don't want to replace it after just 3 months when I haven't even so much as dropped it once.

My recovery is PhilZ 5 Touch 6.0.4.0

I always check MD5 sums before flashing

and do a full wipe

:

- Wipe Data/Factory Reset

- Clean to Install a New ROM

- Yes

- Then Flash the new .zip file etc.

What on earth could be wrong with my phone?

I'll happily provide any more information, as I honestly cannot handle this happening and I have no idea what my problem is...

Thanks incredibly much for any help at all, what-so-ever.
