If I'm understanding you correctly, 
The book cover is the best to protect your device from damage.  However it is very inconvenient because you have to open it every time you use your phone.
I use a soft plastic cover that protects the phone from damage if it slips out of your hand, but it doesn't block the screen.
To protect the screen from damage I keep it in a belt pouch that has rigid sides and a flap top, so I can remove the phone with 2 fingers!
And I have no problems with any signals
Going to or from my phone. 
Hope this helps!

Thanks fir your reply Lindsay. I'm so happy that someone in this forum has replied. Book cover isn't traditional now here in my Country. As you say plastic cover, most of the people using this cover, so I would use it. Xaomi covers are expansive a bit. Still wanna buy it.

Thanks for your cooperation.

Just a heads up!
It dosen't matter what country you are in.
After market accessories for these smartphones are expensive.
When I purchased my phone i spent a extra $25 for the plastic guard.
But I got lucky and found a really nice belt pouch at a flea market for only $7
I guess it pays to shop around!
