Specs look quite good.

Nitin Yadav (Feb 17, 2020) on Gadgets 360 Recommends

If this smartphone comes under 10k in India, I think this would be really good with Helio p35 processor.

Touch problem

Venkatesh (Jul 7, 2020) on Gadgets 360

I purchased a oppoA31 on 27.6.2020 and found touch is not functioning properly on 5.7.2020, some times it works some time unable to open, so approached the shop and they told to return to Oppo Service center. Now given to SC and waiting for their response.
