What Pixel do you have? Modem quality varies and signal strength could play a role. My 9a gets hot in areas with poor reception but is fine at work where I get over a gigabit down.
I haven't been updating AUR packages since the initial incident. Thankfully hadn't updated for a week prior to it. Tonight I'll be uninstalling all the AUR packages I possibly can.
I'm a GrapheneOS user. The duress passcode feature will reboot the phone to a "corrupted data" screen, so it's pretty obvious that it's been used to render data inaccessible.
If you're using something Fire Stick/Android TV, TizenTube Cobalt has been great for me and my family. It has an ad blocker, Sponsorblock, Dearrow, and a few other goodies.
Anecdotal, but I've never had issues with any game outside of competitive shooters that require kernel-level anticheats. If you're not playing those, it could be worth a try.
