So I have a Lumia 620 (Puerto Rico variant) updated to Lumia Black, which was running perfectly fine on Windows Phone 8 GDR3. However once I updated the device to Windows Phone 8.1 a bunch of issues started popping up:
I have turned off Glance and hard reset the phone. Now that I have managed to re-installed my apps, it doesn't seem that a hard reset has done much. The phone still refuses to power off correctly, reboots randomly, lags, and erratically wakes up from sleep.
Any ideas on what I could try next? Is there a way to downgrade back to WP8 GDR3?
- The device will not power off correctly. After more than a few minutes of use, powering the phone down will just result in it powering itself on again. It will only stay off if you power the phone off immediately after start up.
- Occasionally the phone will get very hot near the camera area and refuse to awake from sleep. If you wait awhile and try later, it will wake up and act normally.
- There is a lot of lag, dropped animations, and responsiveness is definitely a second or two slower than with GDR3.
- The Store app will occasionally crash and won't open unless you restart the phone.
- Some settings won't open unless I reboot the phone.
- The phone just randomly reboots fairly often while doing nothing.
