I just flashed 7.2.9 on my Mi5s and I seem to have a problem with my mobile internet. I have a 4G sim with an established connection. I have internet access when using playstore and speedtest apps. On the latter, I even managed to reach speeds of 30ms ping, 15mb dl, 5 mb ul. But when accessing apps like chrome, youtube, or facebook, it says I keep getting timedout/no internet error messages. I tried experimenting and made the mi5s a hotspot and connected my redmi pro to it. Oddly, it had complete access to the internet. So I switched things up and moved my 4g sim to my redmi pro. There, it has full access to the internet as soon as the sim was inserted. I then made the redmi pro a hotspot and connected the mi5s where it too had full access to the internet. I then put back the 4g sim back to the mi5s and the problem still persisted. How do I fix this problem and can anybody else confirm a similar experience?
