Hi,
I bought the Redmi 4A in Gearbet, did the update for Miui 8.5.7.0 and in the first month worked well, then left to make / receive calls in 3 / 4G and internet also stopped working in 3 / 4G. This only happens with Vodafone Portugal. With a sim card from another carrier it works well on all networks. I appreciate who can help.
