User opinions and reviews

This phone is great overall but the camera is quite disappointing, not that it's bad but it could be better. Android 9 runs smoothly with 2GB RAM and storage is sufficient. I rate this phone an 8.5/10

Ive upgraded the Samsung J4 last year and realise this specific phone doesn't have a notification light eg. when recieved messages or missed a phone call. Now I struggle for a year to let this phone go eg. selling it.
