Hello to you... if you've read the answers to your thread starter, then you will be safer.

If you're a novice, try F-Droid and Github. F-Droid is very trustworthy, but at other sites like AC, Github and others - you can get the SHAFT of BRICKDOM if you aren't careful... especially in apps like Discord, or any virtual box app for PCs.

Chat up MoodyBlues,
@ocnbrze or Revenant Ghost - as most of us are great traffic cops - and you will see that wherever we tell you to go and get good files... you will be safe (if you follow directions EXACTLY). Rave on with your Android, & be careful out there with Bat Corona -
