So has the app been put back since the issue was fixed?

So you can have a portable device with a larger screen than your phone? For general media consumption?

Using them? I can understand not getting cracked screens but I think avoiding scratches entirely especially across multiple phones would be a significant feat unless you just really baby your phones.

No it doesn't. Also you can just relock the bootloader. Google doesn't care.

I think that's Samsung. The Pixels don't have a fuse AFAIK.

Well depends on why you're unlocking the bootloader. Some people just want root but not necessarily a custom ROM. Though for some phones a custom ROM may be more appealing than others.

Replace it when your daily battery life starts becoming unacceptable or if the battery itself starts swelling.

What DE/WM are you using right now?

From what I understand, Google One had its own persistent notification (left side) when using the VPN as well as the normal key icon (right side). So now it just has the latter.

It disappeared for me too a while back.

For Android, having apps ask for permission for notifications is a very new feature (debut in Android 13 I think) so by default apps notifications were collectively permitted. It would be up to the user to explicitly go in and disable notifications after the fact. I think many people either didn't know how to access the notification settings or just didn't care enough to disable them.

It's not as powerful as root but it does give you more capabilities. You would need to check the individual app for what functionality and limitations it has with Shizuku.
