User opinions and reviews

Ok this is actually bad, the performance was actually worse, even games can't handle this phone and the home ui hangs and blacks out. I mean seriously, Its not a good idea to update Android 14 to this low-end device.

  • Oppo User

Two years after purchase w/ 45% of storage space free and it is barely usable. The sluggishness is bad enough, but it'll sometimes hang so bad it just blacks out and does a sort of reboot. The base specs are decent enough, so is Oppo intentional...

  • PINK

Used the phone for less than 2 years, but the phone hang a lot and blackout a lot. Not a good device to use
