Nokia Lumia 1020 and 2520 are still on 8.1 update. Don't understand why?
Because they are not supported for Windows 10 Mobile.
But Lumia 950 is now on 10 which is very good
Now ? It was released from the factory on Windows 10 Mobile back in 2015. Did you just wake up from a 3 year long nap ?
I hope they will continue manufacturing the smartphones
Continue ? They stopped manufacturing in 2016, shut down and sold the production facilities - again, have you been in a coma the last 3 years ?
