Does the Huwaei Mate 10 lite have a Flip Cover Sensor@

You can read online in various places that the Android 8.0 Oreo update for the Mate 10 Lite has been delivered since the end of June. However, the update is not yet showing up for me. Has anyone here / in Switzerland received the update? Is there anything you can do to install it manually?

I have a question about the dual-sim slots. Are both slots 4G capable? If not, which standard is supported for the second sim slot => 2G or 3G?

With the p9 the sound was drowned out on instagram and napchat how is it with this phone ?

Does it have a notification led?

Is it region locked?

USB Type-C ?

IP?

is it unlocked ? can I use it in France ?

my new (like refurbished) huawei mate 10 lite says SAMSUNG under 'about the phone'. why? it runs on emui. my 'old' huawei p10 lite clearly says EMUI.
