I got a new phone, the Hisense A2 pro, from Aliexpress. Installing sophos showed me a PUA with a lot of rights. How serious is the threat? And can how can i delete it? I can't find the "PUA-App" on the phone and I can't deinstall it, not even in sophos. Other antivir programms like Norton and Avira couldn't find anything wrong, though.

There are many low reputation apps (especially for e-ink) on the phone, the low reputation is probably because of the e-ink display? Are they safe? E.G.:

Many thanks in advance!
