No network signal antenna repair
So I get very poor network and data (4G) signal on my S7 edge. I read somewhere to replace wifi antenna, but after further research I’m not so sure. The phone connects to wifi with no issues, and now I see there are two separate antennas, top and bottom, which are above and below the charging coil. Upon taking it apart I see the wifi flex antenna cables are under the motherboard, and to replace them also requires a screen replacement, and that there is no visible damage to the cables or their connections.
My question is which parts do I need to replace to get back normal data and network signal? Is it the top or bottom antenna, or both? Any helpful replies are welcome, would be very grateful if you could include pictures. Thank you
