Network cellular mode of my Xperia_X F5121 is "Prefer 4G" after each reboot. IMHO, it's not OK.

The problem is that /var/lib/ofono is not writable. I wrote up a fix for this on TMO:

devel-su
systemctl stop ofono.service
cd /var/lib
mv ofono ofono.backup
mkdir ofono
chown radio:radio ofono
systemctl start ofono.service

After you do this, your settings with APNs and mobile data will stick following reboots.

/var/lib/ofono had the owner root:root and thus was empty. A chown radio:radio /var/lib/ofono systemctl restart ofono.service should suffice (worked for me), no need to backup an empty folder.

@deprecated i tried it and it works!

another problem i have is that 2G/3G/4G doesnt work with WIFI off. It switches between enable/diabled constantly when looking at it in settings mobile data.

@XFish make sure your APN settings are correct for your provider/carrier.
