Well, it's not showing any reading. Factory reset? It was freshly flashed with original ROM and then updated via ota to the March update. Actually, when doing the antenna I had a gsi ROM installed on the phone (either oreo or pie - both worked good except for the proximity sensor, which is a known bug for those ROMs). Now, first time, I changed both antennas with copper wires but one of the wires had bad or no connection (there was good signal on 4g but no internet). At that point the pressure sensor worked. Then i opened the phone again, put back the original antenna (the one in the bottom-left corner) and modified/fixed the copper-wire-antenna in the top-right corner. Good signal, good internet. By the time of doing this I ended up disconnecting the back speaker wires (which i soldered back). After closing the phone back in one piece I started testing it for signal, call, text, sound, wifi, compass, microphone. At this point I found out pressure sensor is not working anymore. Now this is not a very important feature for me but you know how you feel knowing that it used to work and now it doesn't... On one hand I want to fix it but on the other hand I'd like to know what to look for or where to look for it before disassebling the phone again.
