The app is working fine in tested devices. Can you please provide the details of your android devices ?

I have tested your application on a Xiaomi Redmi 5 plus smartphone with Android 8.1 version, I really want to buy but when I test the demo when you have already downloaded a video or photo, wanting to share on Facebook, WhatsApp etc … etc … the application is close, if you provide me with an email I send you a video of how it works

Ok thanks for the information. Please send me video on patoliyaashishk@gmail.com that how app crash so i can find the problem.
