That was quick response. Did you tried reboot your phone?

Same problem , 3G doesn't work at all , it appears as 3Gr  ( roaming... despite being unactivated...and I didn't leave the country). Wifi turns off automaticatly . Last version updated.... and new problem. The easy home appears  automaticatly even whenever I'm using an aplication. Last point, I can't choose battery profies

Yes I restarted my the smartphone. My 4G is back to normal so it was definitely my location at the time however I am glad I found the network selection option in engineering mode because I have been using 'LTE only' option to ensure I keep 4G signal quality when the location provides poor coverage and reverts to 3G
I still don't have the option listed to choose 4G there is only an option for 3G, shouldn't there be 3G and 4G listed to choose from in case you want to switch between the two? I just have to make sure I do not click on 3G because I won't be able to change it back to 4G unless I use engineering mode.

Hi
But I can see on first screenshot that you have activated preferred network type 4G (recommended).
You can always type in to call dialer *#*#4636#*#* then you can set preferred network type and you can tap top right three dots and you can select radio bands.

Hi
You have two separate problems but I don't think that there is any issue with your device.
Roaming mode is activated if you are outside country or if you using third party network provider as they using other network provider and phone picking up as roaming. If you wish use Internet access on third party network provider you need activate data roaming (settings - more - mobile network - data roaming)
Battery mode you can change yourself but if you have activated battery saving mode and auto activation then they will activate depends battery level and settings. (settings - battery saving mode - battery saver - deactivate or change settings there)

Yeh I activated 4G via engineering mode > network selection and changing radio band to automatic it shows up before clicking preferred network typ but on the actual preferred network type options it only displays 3G, not 3G or 4G etc so I would not be able to switch from choosing 3G and revert back to 4G without having to go into engineering mode. 4G is working fine and it automatcally switches to 3G during calls so it is not a major problem but I am sure in the preferred network type options there should be 3G or 4G etc listed to choose from, like I said 4G is working fine so not having 3G & 4G listed in network type is not a problem, possibly a minor bug

Hi
Sorry for your inconvenience but pc can't update your system only change ROM. Yes you can uncheck some partitions or change to firmware upgrade but this is still overwriting ROM plus partitions which you choosed.
WiFi update,  OTA zip file or FOTA  yes those are update as this is only patch for repairing some errors.
Will you tell me your issues again?
