I purchased my C6902 a week ago. I updated the phone through flashtool to 14.2.0.A.290. after which whenever I push the power button, most times it would switch on to the unlock screen but sometimes I have to press it multiple times. But it would always get locked the first time, every time I pressed the power button. I tried a factory reset and the problem still persists. Anyone else facing it? A few other owners are also facing the exact same problem.

Hello,
for several months now i am experiencing a strange behaviour of my Diamond when Powering on.
After powering off the Diamond in the evening when i try to start the phone next morning i have to press the Power button for a long time (up to about 30 seconds) until the phone sarts booting the OS. Sometimes it needs several attempts until i get it working.
In the last weeks the time i have to press the button is increasing.
I am afraid that my Diamond will be only a brick in near future.
Hard resetting the phone and flashing different ROM's (AZTOR, RTT) did not solve the Problem.
Has anyone in this Forum experienced the same Problem and is there possibly a solution?

I've had my phone almost a week now. Last night the screen stopped turning on. I can hear notifications telling me the phone is on, just not the screen. I did a google search and saw similar problems on the N4 and N5. I have tried there methods now over 100 times and still no success. I am holding POWER + VOLUME-DOWN for 15-20 seconds then plugging in USB port but this in a number of variations is not working. Is anyone else having this problem and do you know of a fix for this?
Phone is not rooted if that helps.
Make sure you still have battery (plug it into the wall) then hold down volume up+volume down+power until you get into the bootloader.. From there you can flash factory images or try going into recovery (use volume up to scroll to recovery mode) and do a factory reset. Once in recovery you will need to hold down the power button and tap the volume up button once to bring up the menu for factory reset.
tried that, no luck since the screen doesnt turn on. any other ideas?
you got a sod(sleep of death). the only way around this is to press the power button for 20-25 seconds straight, then reboot. or, there a possibility that your screen stopped working.
Have you tried plugging it into the computer and giving it adb commands to boot into BL?
I wonder if this is an issue with Android in general on rare occasions since KitKat. I had this problem too on my LG G2
yeah, i tried all of these methods and gave up. at&t gave me a new one since i was under 14 days. the lady said they had a whole batch of n6 they had to ship back because of problems and that the newest batch "should" be problem free.
Hi all,
This morning i check if my bootloader was unlocked, because i wan't to give it a try to root it.
I found out it was unlocked (holding down volume and press the power button)
After that, i rebooted my phone and everything worked normal.
Until a couple of hours later, my screen didn't wake up when i pushed the power button.
The homebutton and the backbutton where flickering (going on and off)
So, i waited for a couple of minutes, but nothing changed.
After (i think) 10 minutes, i hold the power button for a couple of seconds and the flickering buttons stopped.
Since then my phone doesn't repsond anymore. I tried the powerbutton for a while, and with the combination of holding the vol. up and down.
So far nothing helped.
Does anyone know what's wrong, and what i can do to wake my phone from its coma?
Thanks in advance!
Enjoy your weekend. Ben
Did you press the power button for a few second before the soft keys started going on and off? Does your phone show a green battery animation when you connect it to a charger?
If the soft keys started flashing on their own, and if your phone doesn't show any signs of life even when you attempt to charge it, I'm afraid this is a hardware problem which no one can fix online.
let's wait and see what more experienced members have to say.
I am currently on 6.0.1 build MOB30G stock. At times the power and volume button don't respond. no matter how hard you press them. If the screen is locked, the only way to turn on the screen is to get a call or attach the charger or simply press the power key for 10 seconds+ and the phone restarts. Rest of the time the buttons seem to work properly. Judging its more of a software problem than a hardware one , I have done a factory reset on the phone.. but the problem has reoccurred. I believe a recent ota update may have caused it.
Any one else facing the same issue?
So I have an X Performance Dual, today as I woke up in the morning I used my phone a while, I then went for a run I leave the phone unplugged and when I came back the phone wasn't turning on I managed to turn it off using the power button + Volume up key, after that it booted to the Xperia screen after that it turned off by itself and now is now charging, not being recognized by the pc on flash mode nor fastboot mode. what can I do?
HI
I have the same. Bootloader unlocked. Upgrading XZ rom and now not woring hopefully I can reset somewhere but no led/usb signals at the moment... Hopefully power will trigger a reset deep in the hardware....
press power button and hold volume up button same time for several seconds. You will feel it vibrate 3 consecutive times. This is a sort of reset with does not delete anything. It just seems to fix boot issues. Try it and see if this helps..
