1) Download the speed test WWW.SPEEDTEST.NET and install it on Hardstone Player
2)Connect Your Mobile Hotspot/wifi and test the speed using the speedtest app.
3) If the download or upload speed is slow , kindly go to the setting>App>Running APP and find the running background apps that have internet/wifi connectivity permissions.
3) Uninstall All the apps that have a permissions to use data and wifi in the background
4) Try the speed test again
Note: Some of the background apps use data connectivity for 24hrs and this may slow the other app such as youtube and etc, so we should test the speed without any added app, use only the system app then test your hardstone player.
