First thing I would try is do factory reset if you haven't done that already

Try reflashing the rom, preferrably a newly downloaded version in case errors crept in there, then try it before restoring any data / apps or even linking your google account. Yours is the first complaint i've seen of this type.

4 type "cat prox_cal" and write down the first value (this is the offset), in my case it was 201

5 sum both values, in my case it was 244

6 Convert it to hex (http://www.disfrutalasmatematicas.co...conversor.html), in my case, F4

7 type "echo -en $'\xF4' > /efs/prox_cal", instead of F4, put your value

8 type "chown system:system /efs/prox_cal"

9 type "chmod 644 /efs/prox_cal"

10 type "sync"

11 type "reboot"

And that's all, we've increased the value and this survives even a reboot.

BR!

A simple way that worked for me was to on-off the NFC, on-off dt2w, and reboot. Everything is now fine.
