A lot of people are saying they suffer the same and me and my friend have completely different devices with different Android flavours.

It doesn’t seem to be what you are saying.

Android 13. Looking in the other replies, it seems pretty wide spread.

Yep, I have it on my Poco F5 with MIUI and a friend that has a Galaxy S23 with stock OS also has the same issue.

Sure, they just need to fix their annoying bugs on Android.

Everytime I leave a tab open and switch to another app, it’s a 50/50 whether I return to a black screen and am forced to restart it or it just works fine.

What you are talking about is the operating system, not the cpu.

The ARM architecture allows much more performance for less power when compared to AMD64, because it runs simpler instructions.

The change to ARM chips on laptops will not make them work like phones, with the exception of much better standby.

Unfortunately, that doesn’t work in Beehaw.
