Well, I got few question about this before, but before it happened on me, I can’t possibly know what’s wrong… So, just now, my phone freeze when trying to writing message. Not sure why it happens, but it stopped writing in the fourth character. Any key can’t respond. So I just reboot, hoping it will solve it.
Then, after phone boot up, I tried message again, writing and freeze again. Uhh… So I connect my phone to PC (the phone still functional, just it can’t respond any direct input) and start telneting.
