Got a Meizu M3 Note for some months til it was stolen, bought a new one and i’m having tons of issues.

Already changed the phone, because it was new, but still having issues.

Many apps like Instagram, Google Maps, Camera, just freeze and takes some minutes to be working again, and have to close it and open several times until it works… Also sometimes it’s just too slow

Did a factory reset (twice) and still not working properly.

Have Flyme, and thought if i could install a new room, maybe it will work… any ideas?

Thank you!
