All of my applications randomly closes, it says""xperia keyonboard has suddenly stopped working.......etc". I have already sent my phone to the service center and i just received it from the center. It indicated in the receipt that they fixed it and have done check ups manualy but my phone has the same problems. I just started my phone after receiving it and in the set up guide and i couldn't even use the keyboard to type the needed information, all it said was that the keyboard suddenly stopped working.
@uliwooly I just got my phone back from the service center, so far it seems to be working well, I just hope it maintains that way. Thank you for your advice, apparently they did a check up on the motherboard and replaced some parts again.
