After 4a and 6a, now is the time for 7a to shine!
Though, is it still in early beta and apparently very few models seem to be affected and there isn’t any word of system update to nuke the battery life on this model. But it goes to show that Google is treating the A series really badly.
I had a different, also known hardware issue with my pixel 8 screen. I also use grapheneos. I used the pixel replacement policy that google had (the phone was still under warranty) and I didn’t even bother to put the OS back to default, just erased everything on it. They didn’t even bother to check for the default software, just that they got a pixel 8 back from me.
