[Baby_yen]

The visual quality is like painting. The visual problem appear only when using apps othet than duo, like whatsapp,messenger,snapchat,etc. Is it my problem? Any solution to solve?

Hi I think it's a problem with WhatsApp, even my phone looks very patchy, Google DUO looks much better. But I think it can still improve.

Btw WhatsApp calls on my iPhone is very good
