[SOLVED]Guys my phone rebooting automatically - Galaxy Grand 2 Q&A, Help & Troubleshooting

Device -G7102

Thats an serious issue...i think its the problem of your power button maybe it's broken or something...have it repaired cuz RR 6.0 is an perfect rom nd it cant give bootloop

Any recent application installs which might have caused this?
Sent from my GT-I9505 using xda app-developers app
if i remember correctly the last thing i installed is quadrant benchmark
is it possible that something on the root/data/app got missing or uninstalled?
this is the first time i encountered this problem. , havent seen it before in devices that ive handled
It sounds a little like the cache is corrupted (can happen if it doesnt shut down cleanly).
I had similar behaviour on my galaxy note.
The first time I did a factory reset and that fixed it (remember this wipes all data).
The second time I tried formatting the cache partition first and that fixed it.
When I did those I was using CWM recovery. I cant recall the stock recovery options.
If all is the same between phone versions, to enter recovery you hold down home-power-volume_up til it boots.
Sent from my GT-I9100 using xda app-developers app
from other posts from orher devices i have read they say its cache but the problem is when i turn it on it doesnt even boot the iniitial logo (samsung galaxy s4 gt-i9505)
it doesnt show up anything. . . screen doesnt lit up so also a problem how do i go now to recovery if the screen doesnt even turn on (the phone vibrates as a respond but the LED and the Screen doesnt lit up)
i know how to enter recovery mode. . . thats the only problem (softbricked)? this phone was bought on the official day of release
I'm having the same problem... Did you find a solution?
Anyone Solve this?
Getting quite anxious about not being power it on
Alex
Was anyone able to solve this? I'm experiencing the same problem. I can switch it on after removing the battery for a long time, but I can't seem to be able to get to recovery, or reboot proprely. Please help... thanks!

having the same problem too
1. you still CAN go to the download mode even if screen is off (I flashed full stock but this did not resolve a problem)
2. I was able to turn on my phone after many attempts: (press power, after vibration release) - I did it about 30-50(maybe more) times and my phone boots up. But after rebooting it again doesnt turn on (again many attempts helps me).
3. I have observed - in my phone vibration turns on after 6s after power button is pressed, in a correctly working one - after 4s.
(sorry for my english)
Was anyone able to resolve this?
same problem here too !! but seem to have found a solution
My galaxy s4 was acting all weird one day, randomly it switched off and wont turn on but keeps on vibrating it was only 3months old I thought it had some serious hardware issues because I tried all the means to resetthe phone but nothing gave me a solution even tried another battery no effect it wont turn on even if it did turn on it would randomly shut itself up within notmorethan 15min I stay in india where i9505 is not sold so Samsung officials would not take my phone for service as they feel its different from i9500 in all means I got fed up and brought myself a new phone a 5s .
A few days before I badly wanted my galaxy so sat whole day searching the internet for fixes couldnt find one . I got angry and smashed the phone hard on the table .to my surprise it gurned on (was connected to the charger ) turns out some phones have a problem with there power button and mine was one of them
I didnt get my button fixed yet but after turning on not using the power button helps . Have been working for 4 days in a row now no problem what so ever . But if I lock my phone using the power button then it tends to get the same problem again ! So guys get your power button checked
Try to fix the button with WD40, worked for me.

When you say you upgraded the firmware and nothing happened, what exactly did you do and what steps did you take?
Also, for hard reset did you try vol down + power then vol up + vol down?

problem with zenfone 5 boot

hi guys
i am facing a weird problem
when i reboot my phone,the phone goes off normally but after switching off it doesnt boot back(which it should do in 4-5 sec coz i rebooted)..the phone would remain switched off and would also not switch on by pressing power button..it switches on when i press power button along with volume +/- key.. the problem was every time i rebooted
the problem was first noticed when randomly rebooted after that i changed boot animation and since then the problem started.
seeing the problem i changed bootanimation to stock and unrooted, reflashed stock firmware via sideload and did a factory reset.
this procedure reduced the frequency of this problem..but then i went to service centre and they changed my motherboard...THEN ALSO FEW DAYS BACK I AM FACING SAME PROBLEM.
I'M UNROOTED AND ON STOCK LATEST LOLLIPOP FIRMWARE.
PLS HELP ME GUYS........................

screen flickering issue plzzzz

guys i was using miui 8 rom with phantom kernel
while using it my screen started flickering and just got black
when turning on my phone screen starts for sometime and then same story
also when i turn on my phone in recovery same thing happens
can anyone plz tell me what the problem is
it first shows boot logo and then goes black
If it is happening in recovery too,then it might be a hardware issue.
But try flashing stock ROM.See if that solves the problem.

Phantom kernal over clocks your GPU.This might also be the cause of flickering.So try flashing the stock rom and see what happens.

do u got an update to stock 5.2
and by the way is volte working in that
Screen Flickering is common issue the main cause is because the synaptic driver is not quite compatible to ft5x06 which results in flicker around some interval there is no solution for it lenovo did sh!t with the driver the way out is only rewriting and adapting the driver for our phone accordingly

Maybe your Ultra have Hardware problem? Try flash RUU with other SD Card. Try everything you know with software.
