The cell phone UMI X 2 must really be getting famous, as it has appeared a generic silicone cover in some stores on the internet. I took and bought two for me:
The seller of the site AliExpress, that's like a municipal market of small shops and Chinese vendors, was announcing two covers for less than 6 U.S. dollars. I gave a talk on it and asked me to send a clear and another gray.
The covers are very flexible and protect the cell.
The bottom has a hole for the microphone and USB, In addition to the speaker that is much better suited in this cover than in the original.
Instead of trying to do a silicone button, as the original cover, This left a hole to access the buttons on the phone itself. Much better, so to avoid accidentally pressing.
I bought these covers on AliExpress, but as this site has different sellers of the same product, as well as the Ebay, It may be that the links left below stay unavailable. So, I left a link to search for cell phone covers UMI X 2 at the end, where it will be easier to find the product or similar.
