Rating: ⭐⭐⭐☆☆ (3/5)

3/5. A lifeboat for a sinking phone, but you’ll be drifting on an old, unsupported sea.

Only download the rollback package from OPPO’s official community website (not random forums). Fake “rollback” files are common and contain malware.

Essential if you hate the update, but dangerous if you don’t read the fine print.
