I have an S9 and recently, right after the update, when I watch videos I have one of 2 issues:
Instagram IGTV videos: after a certain amount of time (varies per video, usually less than a minute), the sound stops. The video keeps playing, but with no sound.
YouTube/Facebook/Hulu/etc videos: after about 20-50 seconds, the video stops. I hit play and it starts again but then stops again after a little bit, roughly same amount of time. Start/stop/start/stop.
I haven't installed any new apps, I've restarted it, I've checked all battery and sound settings, and I can't access these apps in safe mode so I can't tell what the culprit is. Any ideas?
Thank you for reaching out. I would recommend force stopping and clearing the cache for the apps your are experiencing these symptoms with. Give these steps a try: go to settings > apps > tap on the app your are experiencing the symptom with > tap on force stop > then tap on storage and clear the cache.
Next, I would recommend wiping the cache partition on your device. The system cache partition stores temporary system data. It's supposed to allow the system to access apps more quickly and efficiently, but sometimes things get cluttered and outdated, so a periodic cache clearing can help make the system run more smoothly. Give these steps a try:
You're welcome! Regretfully, the next step would be to do a factory reset on the phone to correct any possible software glitches. Be sure to do a complete backup before resetting. https://www.samsung.com/us/support/answer/ANS00062029
