Hi,

I installed skype today from aptoide store but I was unable to login I'm not sure if the crash is related to this, but after installing using any android apps phone suddenly goes blank then charging symbol appears even though no charger is attached after a while screen shows some light and tapping on it brings up lock screen. This happened twice when I tried to use skype and once I was playing a game after installing skype.

Is there a way to know what is going wrong?. I'm using Sailfish OS 1.0.8.21 I recently brought this phone and don't want to screw it up :-). So any help appreciated.

Edit: Ok it doesn't seem to be related to android app it happened again when I'm using sailfish-browser, suddenly charging symbol appeared as appears in powered off jolla and the screen lighted up and lock screen appears after a while! I'm not even sure if its a crash or something else.

Edit 3: This trace might not be related to crash as I can see it every time I boot the phone so I'm really clueless why the charging symbol appears and jolla restarts. Is there anyway to find out what went wrong? I'm new to journalctl and unsure how to get more information.

Hi,

I installed skype today from aptoide store but I was unable to login I'm not sure if the crash is related to this, but after installing using any android apps phone suddenly goes blank then charging symbol appears even though no charger is attached after a while screen shows some light and tapping on it brings up lock screen. This happened twice when I tried to use skype and once I was playing a game after installing skype.

Is there a way to know what is going wrong?. I'm using Sailfish OS 1.0.8.21 I recently brought this phone and don't want to screw it up :-). So any help appreciated.

Edit 1: Ok it doesn't seem to be related to android app it happened again when I'm using sailfish-browser, suddenly charging symbol appeared as appears in powered off jolla and the screen lighted up and lock screen appears after a while! I'm not even sure if its a crash or something else.

Edit 2: Ok further checking of journalctl I found some kernel trace with cut here instruction after this phone rebooted and possible register dumps. Not sure if this will be helpful but I'm just pasting it here.

This started to happen after upgrade to 1.0.8.21, was there fix to kernel in that bug fix update? Any one please help :)

Edit 3: This trace might not be related to crash as I can see it every time I boot the phone so I'm really clueless why the charging symbol appears and jolla restarts. Is there anyway to find out what went wrong? I'm new to journalctl and unsure how to get more information.

Edit 4: I had several restarts within 10 minutes and I was baffled only thing I did was sitting in a car where sunlight was directly falling on me and my phone was inside my pocket started buzzing. I noticed its rebooting and it went for about 5-10 minutes after again digging through log found this

So is battery heat which is causing reboots? I've seen battery heating during android games playing but never after. Also I never faced this issue with 1.0.8.19 this only started after recent security update. Did something broke in this?

Hi,

I installed skype today from aptoide store but I was unable to login I'm not sure if the crash is related to this, but after installing using any android apps phone suddenly goes blank then charging symbol appears even though no charger is attached after a while screen shows some light and tapping on it brings up lock screen. This happened twice when I tried to use skype and once I was playing a game after installing skype.

Is there a way to know what is going wrong?. I'm using Sailfish OS 1.0.8.21 I recently brought this phone and don't want to screw it up :-). So any help appreciated.

Edit 1: Ok it doesn't seem to be related to android app it happened again when I'm using sailfish-browser, suddenly charging symbol appeared as appears in powered off jolla and the screen lighted up and lock screen appears after a while! I'm not even sure if its a crash or something else.

Edit 2: Ok further checking of journalctl I found some kernel trace with cut here instruction after this phone rebooted and possible register dumps. Not sure if this will be helpful but I'm just pasting it here.

And going down in the log I found some register dump again not sure if its helpful
