has anyone tried buying a HK set or a set from elsewhere then flashing local firmware and gaining full functionality?
Erm not me... no idea of flashing and what's the difference?
I'm using the hk set xperia iv, I do get volte and 5g showing on single but NR NSA...
One of the con is Netflix, I can't get it to work with better resolution. It's shows l3 for Netflix app itself. But I am able to get 4k for YouTube.
And for warranty, If you bought overseas, SG Sony don't cover or help repair the phone. You will need to send back to the country of origin.
There's a new firmware update 64.1A.0.929 for hk set.. Guess should be security patch ...
