Why is the touchscreen unresponsive for a while?
Hi. I have this weird problem with my phone. When I turn off the screen/lock it, if I turn it on inmediately or after a bit the touchscreen won't work. It won't respond to my pressing and I have to leave it there for a while.
After a period of unresponsiveness (which can range from about 15 seconds to several minutes) the touchscreen will start working normally, until I lock the phone again and it does the same thing. Every time. Sometimes I can hear the "locking" sound a while after I pressed the "lock" button, which suggests that the problem is that the screen enters a long "locking" period rather than doing it instantly as it should when I press the button.
I've had this phone for a couple of years, and this problem started some time after I had to do a factory reset because it had entered an endless loop of turning itself on and off. So I don't know if this is a software issue or a hardware one, and in either case, I have no idea how to solve it. For that reason I'm asking here before trying another factory reset, since I don't know if that'll solve anything.
Can anyone help?
