Hi,

I have a meizu pro 7 with the global rom version Flyme 6.1.3.2G.
I am having problems to select 4G as preferred mobile data type.
When I try to select: prefer 4G in the screen as shown in screenshot, it disappears and I get thrown back to the main screen.



When I pull down the option window on the main screen from the top of my phone, I can recall another window:



I can select the lowest option: 4G as preferred network, but when I check again in the settings window under mobile data the only 3G is checked. When no 3G is available I get no network connection at all.

I already asked tech support for help, but they couldn't and said to post this in the bug section. However I can not post in the bug section of this forum.

Does anybody also have this problem? Anybody know a solution for this?
