Greetings,

I installed GPAC android apk (stable release 2.2.1) on an ASUS_Z017DA phone (android 7). I then used it to play a mp4 file that was working in the GPAC client running on Linux. I found that I could hear the audio, but the screen was all black. 
I have attached the relevant logs at the end of the post. 
My questions are below:
•	Are there any suggestions for solving this problem?
•	Which version of the Android phone is working fine with the GPAC Client?
•	What make/model of Android phone is recommended for use with the GPAC client?
Any hints are highly appreciated.

Thanks,
Ei Kyi Phyu Khin
