Thanks Volker ! Smart workaround.
So for anyone who would like to take a look. I’ve attached “logcat.zip.ttf”. Please remove “.ttf” from the filename and unzip to reveal the logcat.
I’ve started the logcat just as the call comes in, but I get a similar behaviour when an app crashes. This is now happening more often (5-6 times a day), but it always appears to recover after about a minute or so with a “Close App” message.
I’ve tried looking up the different entries, but I haven’t manged to find anything relevant online. To me it looks like the error occurs at 15:02:38 with a whole series of GPU related entries. This roughly fits with me observing the screen stuttering for a second or two before the screen freezes completely. The ring tone continues to play and stops as it should when the other person hangs up.
Any help is appreciated. I guess my initial question is, does it look like a hardware or a software issue? My instinct is a hardware issue, as it appears to be getting worse.
Thanks for looking.
