Any reason for letting go? Is it bad quality? Ops.

sticking with apple case lol, i nv use the rhinoshield when i received till now

I see, apple case = silicon case right? Nice grip on hand, but sadly they don't have transparent case, as I want to show off the sexiness back of my phone.

leather and silicon 

Do they cover bottom speaker part?

No they don't.

Do they cover bottom speaker part?

I also remember, it is not. But people like it cause it is comfortable on hand.

Thanks bro..
have been away recently.

Btw, i have updated to 11.2.2 and somehow all the issues mentioned were fixed.
The only thing problem now i face is the notification's does not appear for whatsap, telegram and other messengers. I did the enable notif from settings, but somehow its not working. I did reset too and the issue still remain.

Try click on the DND?

as in Do Not Disturb ?

The silicon ones are ok, the leather ones, I personally feel is a little slippery. Few times, I hold it, I almost drop the phone. The leather is heavily waxed.

And, the advantage of bottom speaker not covered is that you can plug in to those desktop dock speaker like JBL OnStage or OnBeat.

I see, now i know the purpose of designed not to include the bottom part. So the silicon one is recommended here?

For Apple Original Case, yes, Silicon case is quite good. I'm using Spigen Ultra Hybrid Crystal Case and happy with it. Transparent and can see the beauty of iPX.
