Happened again. Was in an app other than Chrome for about half hour and felt phone getting hot. Process monitor showed mediaserver using 35% again and once again a force stop on Chrome fixed it immediately.This has been happening to me. I notice the phone getting hot and when I look at CPU processes with Simple System Monitor I see mediaserver using 35℅ of the CPU. I can force stop Chrome and mediaserver stops every time. Uninstalled Chrome for a week and never saw it. Installed Chrome Dev and had the issue within 24 hrs. Phone hot in hand, discover mediaserver pegging CPU and only way to stop is reboot or stop Chrome. In every instance I am not using Chrome when the issue occurs. I am using other apps. I have a 128gb sd card with no media export m except phone pics and videos on DCIM.
i'm suddenly having this exact same issue, mediaserver is using up 53% of my battery and my phone is getting hot and going slow.
I have taken out my memory card but i'm still having the same issue
I have been having this problem on and off over the last month in my s7. Never had it on my old s5. I removed all media, then my micro so and I still had probs.
Anyway I solved my issue by ditching chrome and forcing it to stop. I believe it was to do with ads, especially auto play ads.
I am now using Samsungs own browser with adblock plus and not yet a sniff of any media server raising it's head. This is after a few days browsing, viewing YouTube and taking pics.
Might be worth giving another browser a go.
I've got the dreaded mediaserver battery drain.
The phone is running hot, it's also gone janky and a little less responsive and the battery is being obliterated to the point where it's draining at a rate similar to having the screen always on, also stopping Doze from kicking in.
I've deleted app installs since I noticed the problem (thought Spotify was the culprit but no). I've wiped cache from the bootloader and from Storage menu.
What else should I try before I resort to factory reset?
Try the Samsung browser, it has adblocking, and it's pretty fast.Personally I'm not yet sold on any mobile browser. Dolphin slowed my phone down a crazy amount and Chrome isn't much better, plus it has limited customisation options.
