I really like your rooms and used to use it on my note 8.0 ( the tablet not the phone )
As my tablet died i decided to go with Huawei Mediapad M3 this time and to my surprise there is no
room for it .. it is out for nearly 2 years , it is an amazing tablet with very good spec but by searching there is not a single custom room for it !!!
Please take it into your consideration
