I have been using the cover for a couple of days now and found that the bottom side of the cover is very delicate and not very steady. It gets up and down even with slight disturbance from my hand. This makes the experience of using this cover very poor.
The phone cover I purchased for Reno 7 is of a very good premium quality nd colour. It is just a bit thick, otherwise gives a very premium feel to it. Importantly, it does not slip from hands. Highly recommended.
