I use the XQ-50 Pro. When I play the flac file below with LDAC on the android phone, the XQ-50 Pro crashes 100%. http://gofile.me/6E8Gv/jQUd1qgFn The playback screen is frozen and no sound is output. The Power button also does not work. It is restored only when the power cable is disconnected. Due to this problem, the product cannot be used normally. Please improve this problem quickly.
