When ever I play any video from firefox or chrome , there is always a lag ? can you please suggest something better.
depends on your intenet connection,on how many users there are on your wi-fi at the same time, how many devices if you have a smart home…
try to reduce to the minimun all this and you should see an improovement!
By lag do you mean audio and video are not in sync via Bluetooth? Or do you mean the video playback is not smooth?
Video is not smooth? audio video sync is fine.
Playback is not smooth.
