[Q] Galaxy S4 Constantly Restarts

[emcardle660]

Bit of an annoying problem, my Samsung Galaxy S4 i9505 (Rooted) constantly restarts at random now and again, and it can be very frustrating.

Also, I have the app 'App Master', which when the phone is restarted it shows the boot up time. When my phone randomly restarts, the boot up time could literally say it took hours (It's went as high as 40 hours... not sure if this is relevant or will help but yea...)

Also I get logged out of everything (facebook, twitter...) whenever my phone restarts which is very annoying.

Any help would be appreciated, thanks!

See if the same happens in download mode too.

If yes..you have a stuck power button.


If no, have you removed all the knox related apps? they cause this too. Deknox your phone.

If still persists, data wipe or flash stock rom..disable knox first via recovery..then proceed with normal rooting..

Thanks for the reply! The power button is alright, knox is on my phone though... So is it completely safe to remove it then? (i dont think ive ever used it before anyway so i dont need it)

Yeah. Knox is the culprit then.

Check the i9505 rooting methods and if any deknox script is there.

Or simply if you are rooted..install the "system app uninstaller" app from the play store..(a red recycle bin logo app) and delete all knox content.

Bdw you wont be able to use knox anyway if you have a knox trigger

Very true, I think it's unusable anyway being triggered during tampering

I've removed everything related to knox so hopefully that fixes it

Thanks for the help

Screen not being usable is the issue of the charger. Try changing the data cable.

Restarting issue could've been linked to a partial stuck power button or maybe because of an improper way of flashing or improper way of flashing kernels

Bdw did you change it or get it changed.?
@AntaresOne : Another hardware issue bro. Help him

I change it. I use different data cables and is always the same, I switch batteries with my wife's s4 and is the same problem.. One thing that I noticed last night is that the indicator led stays on (blue) even after I power off the device.

I'm starting to convince my self that it might be a hardware issue.

Ohh.

Now it is kinda certain that the way you changed or got the charging jack changed has a problem.

Try reassembling the charging port

This can be of great help.

Hello, it's a weird case.

Try to download the latest firmware available and update through Odin, then install a custom ROM (to fast de-Knox). Install CM11 M9 and leave original kernel, let your battery discharge until power off, connect to the charger and power on. Don't use it, see if charger more than 80% without reboots
