I have very low sound in top speaker during calls on my Mi6. The problem came with MIUI10 2-3 weeks ago with weekly rom . I read somewhere that this is a software problem. Do you know something about this problem? It's very annoying..
On my MI6 nothing happening when I connecting pendrives to the phone. I tried with different pendrives and different OTG cable/adapter. It didn't work on MIUI 9 and now it is still not working on MIUI 10.
