How exactly is it hashed? There aren’t that many possible phone numbers, so it might be viable to just try every valid number until you find one that matches

Blaming Spotify for this is like blaming the company that made your TV for showing you ads that are part of the broadcast. Unless Spotify makes the specific podcast you’re listening to, they’re just playing you the content someone else made, including the ads they included in that content.

It’s marked solved, but since OP didn’t post the solution:

-e uses basic regular expressions, where you need to escape the meta-characters ((|)) with a backslash. Alternatively, use extended regex with -E

$ echo a | grep -E "(a|b)"
a
$ echo a | grep -e "\(a\|b\)"
a
$ echo a | grep -e "(a|b)"
$ echo a | grep -E "\(a\|b\)"

The x390/x280 are the same era as these but smaller, so might be a better fit here. The X390 has soldered RAM though, so I’d look for the 16GB version if you can find it (there’s not much of a price difference used)

I wouldn’t wait that long in the hope that Google release another Pixel tablet and that it then fixes the issues you have with the current one. IMO there’s too much risk that either they don’t release it, or they don’t release it at the time you’re expecting, or it doesn’t change things you care about, or they change the price/features.

I’d say buy the best (/least worst) thing you can actually get now.
