What are the two connections from the logic board to the battery module? The small one broke on my phone, but I don’t yet notice a difference in functionality.
I got the same issue. Now I’m having signal problems. Did you notice something?
Yes. The battery module houses the antennas, and that connector is what bridges them to the logic board. I had to replace my phone. You could replace the logic board if you find it cheaper. Or maybe have someone solder it together, though I’m not sure that’s possible.
My phone cannot produce record sound.
what could be the problem?
what is the main problem if the lg g5 is invalid battery then shut down? do i need to change the back panel or what? thank you for answering hope you notice this..
