Cannot install any apk on my device
Please see picture attached.
I'm unable to install any applications and install button does not react on anything. Opposite button "Cancel" works fine.
Very weird situation which I never had before.
This appeared to happen when I flashed the latest Stock ROM with GNG1 bootloader and to resolve this problem I have tried 4 different Custom ROMs within the last few days but no luck, problem still persist.
And yes, I have performed full wipe and ticked "Unknown Sources" in settings.
What is interesting, problem is going away for short period of time after reboot.
