Hello everyone,
I have UMI Hammer with default stock firmware 4.4.4 and suddendly, after about two months of use, It lost signal
Its only searching for network, sometimes pretending to be connected, yet when I try to make a call it goes back to "Searching"
I havent done anything to the device settings or anything like that.
