My phone is connected to the Virgin Mobile network in the UK and is struggling to get above 2 notches on the signal strength bar.
About Phone setting shows signal strength of around -100 dBm and asu of around 2.
I have recently changed the lcd on the phone so just had to transfer the mobo, camera, sensor, vibrator, antennae and buttons. All went back in ok and all connections triple checked. The antenna is the same as the one originally connected to the mobo (although this may only be the Bluetooth antenna?).

Does anyone have any ideas?
All advice gratefully received 😉
