Loss Networks Of Mi5

[yassgeta]

Hello,

I have a problem with an MI5 that captures very poorly the total network loss networks while with my MI4S it works very well.
For info I am at bouyg I tested a site where I had more networks with the MI5 and with the MI4s I capture in H +, same with a MI5S I am in H +.
But outside when it captures I am in full 4G, I understand not a hardware problem?
Has anyone ever encountered the same problem?
I tested with the ROM xiaomi.eu in MIUI8 stable and MIUI9 its nothing changes.
An idea ?

Thank you

Hey, i have the same problem with mine mi5. It randomly loses recepction no matter the area(it happens also in place with very good network coverage).
The only difference is that i'm using the global stable.
