Quick update after some experimenting:
- I had previously played Diablo Immortal on this phone before the update but it's been uninstalled for some time. I just installed it and it works fine with the exploit setting enabled.
- I have never installed need for speed on this phone and I just installed it. It appears to work just fine without the exploit setting enabled.
I haven't yet been able to test some of the listed games on the other Pixel 7 Pro running GrapheneOS in my household but this information seems to point to the issue not being the games themselves but something unique to our individual setups.
The pattern appears to be that some games installed before the update will no longer run, even after re-installation. What artifacts could they be leaving behind or what new setting did the latest GrapheneOS updates introduce that might be enabled now that weren't before?
