why my nokia dont get the update oreo 8.1? i have the nougat 7.1 !
This is a known issue, that should be fixed after installing June security update. If not, people succeeded to fix it like this: backup the phone, then reinitialize the phone and use the backup to restore it. 4G is then back.
Just received August security update and 4G and mobile data are working now, great even it takes 3 months to recover.
I'm using Telia operator in Finland. I just install security update, restart phone and everything works like before 8.1/may security updates. No new settings or anything need to be set up, just install and restart. Also Nokia pro camera app is opening very fast.
I'm in Vietnam. I have 2 sim with 4G from Viettel and Vietnamobile Operator.
Viettel 4G supports LTE band 3 ( 1800Mhz)
Vietnamobile 4G support LTE band 8 (900Mhz)
I find on GSM Arena that Nokia 7 support both Band 3 and Band 8.
But I can only use 4G of Vietnamobile, Viettel 4G can't be connected.
I think there is an issue with LTE Band 3 (!?) while China is provide 4G network with Band 3, 38, 39, 40, 41....
Mobile data is still unavailable after august update. Not with 2G, 3G or 4G. Also it looks like 4G just can't work without mobile data so it is not available even for calls. Strange thing is that 4G works after phone reboot for a short period of time and I can make a call but then it just switches to 3G
