There’s no definitive information available as to what’s causing the breakages. But one recurring theme is users saying they discovered the cracked glass after taking the phone from a warm to a cold location.
Welp, I might put my idea to get the Pro on the side for now.
I already have bad memories of my first Android phone having its LCD screen break easily and start to bleed during winter for the same reason (happened two times).
As a reminder: Pawoo was never run by your typical volunteers.
It was made by Pixiv (hence the particular link between those two) and got already acquired once by Russell Co. in December 2019.
Companies can run their instances (some even contribute to the project!) and it's not always a bad thing... but just double-check if they don't do weird things with it since you're still giving them data.
