I'm having a problem with the touchscreen/display of my phone while on call. I noticed the problem while making a call to my network's customer service hotline, where I have to press digits to redirect me to a specific CS representative. The touchscreen works for the first few presses, then the display hangs but it still registers my presses.
What happened was I used the ear speaker, so I had to put it on my ear then away to press the digits. After two times doing this, the display would hang but it still registers my presses. The on-screen buttons, however, responds with the display. I pressed the home button and it brought me back to my home screen, but again the display just hangs. What I did as a workaround is to use the loudspeaker, now the display did not hang.
I am on latest .14 firmware.
