I recently purchased QHDTV ( http://www.evybuy.com/3-months-arabic-iptv-code-french-italian-turkish-portugal-in-qhdtv-account-support-apk-m3u-smarttv-mag-p-1686.html )
I set it up on an Android Box ( https://www.amazon.com/gp/product/B0787ZB85C ) but it would randomly stop working, the channels not the actual Android box.
I tried using both Wifi and wired, and problem still occurs. I also have ZaapTV on my Roku and I've never had a problem with it since I've had had over a year ago.
Could the problem be from the Android Box or is it QHDTV?
you can try Iptv box Ninja . It's the best service for Arabic channels.
