Hi, I am using coolpad note 3 and I am facing an issue as on auto mode of 2G/3G/4G the network hangs, data stops, incoming and outgoing calls done not works, anyone who is calling hear not reachable message, but the network bar on display shows full signal and the data icon is vanished and this happens after 5 minutes of restart or network search and problem last till next restart or network search.
But surprisingly it works perfect of maual 2G mode. but it was working fine when I was on Airtel network but as soon as I shifed to Vodafone the problem started. I have changed the sim, changed the location but still the issue remains.
