Xender app for sharing files is useful but there is some negative also. My android phone is Oppo Neo 7, When I installed Xcender app the device become to hang. The working of the mobile became to slow. This app takes more time for transfering big size files from one device to another. This app used more battery consumption. When open the app the device become slow.For any quiery contact me: pcpismail9020@gmail.com
