Chosen Solution
I have a Samsung Galaxy A3 2016 SM-A310F. As soon as I get inside my house, automatically my Orange provider network to make calls dissappears. I tried to change it to 2G only, 3G only. Searched networks manually but even with that, it got registered in network, and 5 minutes later, lost again. It was bought in Singapore. I heard that maybe the motherboard is the issue. Once I go outside in the street, works again. Is there something that I can do about it? SIM is not the issue. IMEI is not the issue. Any advice will be welcome. Thanks in advance to all.
there can be many causees of this issue. The carrier signal not penetrating your walls (Fringe Service); the pickups not receiving the signal; the networking antennas not amplifying the signal; The boards Chipset not processing the signal; or the phones software not recognizing the signal. I would suggest replacing components in that order.
have you tried a network refresh?
