Infinix Smart 3 User Reviews and Opinions


  1. The phone is super sleek.
    It's different from the Smart 3 plus having a lower RAM of 1GB and 16GB ROM. Runs on Android 9Pie with XOS skin 4.6 on it. No lagging so far on the quad core 2.0 GHz processor. But the best experience yet is the camera. I have only had the phone since Monday, 29April 2019.

  2. Infinix smart 3 dont have music app and gallery it uses google gallery. Now the problem is there Google gallery leak ur privacy photoes personal items on internet.
    Solution of privacy leak.

  3. This phone has been giving me problem since I bought it. Especially when it comes to gaming some of my games just keep stopping and some wouldn’t even start especially with games like PES 2020 and Tennis mania and I have tried to update the phones system but it keeps failing after swallowing all my data

    • You should look for a better and more recent phone. Yes it hangs due to the low RAM size.
      No music app but you can download one.
      No gallery. It comes with Google photos
