hello, after a screen replacement with a refurbished one, now i have poor wifi and bluetooth signal on my lg g5. i suspect an antenna issue. someone know what could be the matter?
yup sounds like the antenna. order a replacement and swap it over.. if this doesn’t fix it, will most likely be a logic board issue. 90% of all cases on the device is the antenna. furthermore make sure you reseat the antenna connection.
I had exactly the same issue. Check the antenna cable, it is under the motherboard, one of the connectors was disconnected, in my case and that solved the problem. Probably, when I was replacing the screen I accidentally disconnected the cable.
