Im having a weird issue since the last 2 days with my samsung galaxy 551 (callisto), when i turn on the phone the touchscreen works perfectly, when i open the pyshical keyboard to write something, the touchscreen stop working, i have to turn off the screen, wait 2 or 3 seconds and turn on again and the touchscreen start working again, this issue are present since the last 2 days, i have mothns using custom roms (CM7.2, Jellybread,etc) and this problem are present in all those roms included the stock 2.3.6, is a hardware issue? and which component are faulty? thanks
Do you got any solution to your problem?. I have nearly your same problem, but the touchscreen isnt working. I got to work it sometimes by locking the screen and unlocking it with the power button, but since yestarday that workaround is not working anymore. Any ideas?.

[Q] Note 2 Standby problem

Hey guys,
i got a problem with my note 2. Sometimes i can't wake up my phone by pressing the home or powerbutton. The LED is blinking because i got a whatsapp message, so the phone is on. This happens once a week and this is really annoying, because i have to pull the battery to reboot the phone. It happened 2 times now and i haven't found a solution for this bug. I can't send the phone to samsung because i am sure, that they can't detect the issue, because it just happen once a week and i know that they just check software problems with a script and if the script says the phone is ok, then they will just send me the phone back.
i have to mention that samsung had already replaced my mainboard because of a kamera problem. since i got the new mainboard, i have this problem.
anybody have the same problem and knows how to solve it?

gt-p5210 tab 3 10.1 randomly bricked

I have a gt-p5210, which randomly bricked. Now it doesnt show any lifesigns, its just a expensive paperweight. I checked the battery: works. I checked the charging cable: works, the screen: works. It seems like everything works fine but not the motherboard. Is there any way I can fix the motherboard (for example reset it) or recover the data from it? Or could be other things causing the issue?
Thanks for all answers
