Android Plex App "Unexpected runtime error"

Plex Players Mobile Devices

Server Version#: 1.41.6.9685-d301f511a
Player Version#: 2025.12.0
Phone 1: G9 Pro, Android version 10
Phone 2: Galaxy S22, Android version 14
Synology server: DS220+, DMS 7.2.2

Haven’t seen others mention my particular problem since the app update–none of my TV shows or movies on my server will play on my phone while connected to my home network (or via mobile data). They will, however, stream to Chromecast (everything on same wifi network). Not sure it’s a server setup issue, music does stream in the Plexamp app (regardless of home network connection or mobile data) and I checked my remote access settings. Not sure if there are other settings that tells Plex it’s allowed to play media from my server that the new app is messing with?

At one point a few days ago, I deleted the app and reinstalled, and it installed the old app (guess Plex rolled it back for a bit) and streaming from my home server worked again–but they re-released (?) the new app, and again I can’t actually access my files. I get “Error Occurred Unexpected runtime error.” pop up every time I try to play a video file.

I don’t have iOS devices, but both Android phones I have are unable to access videos from my Plex server on the new Plex app.

Anyone know if this is a “user is not a media server network technician guy and doesn’t know what he’s doing” issue or a “Plex’s app is doing something funky, please just roll it back to an app that worked” issue?

I’m having the same exact problem, galaxy s21 tho. Hope they find the fix

I’m in the same boat for downloads - literally the only feature I wanted when I paid for the subscription. Extremely frustrating. And distressing to find a 17 day old post with the same exact issue.

Feeling extremely burned honestly.

Same problem

I have this issue after recent update of the app. Appears randomly on some episodes, plays others fine.

I had that error occur just a couple of hours ago playing a downloaded video.

Oh, look, they fixed it.

I get this same error, only on some videos.

For me it was because my videos are vos sub subtitles and I found in some other thread that’s an issue with the new app.

I turned off subtitles before playing the video and all worked fine.

2025.16 Android mobile has a problem with VOBSUB subtitles. When enabled, the video does not play and “Error Occurred, Unexpected runtime error” is displayed.

Plex is aware of the problem. It will be fixed in a future release.

Wow that was it for me. I’ve been scouring the forums looking for a solution for random videos not playing

Oh, darn. If that’s the solution, shows will be unwatchable for me. I need subtitles.

I just installed an old version of the app and turned off updates until they fix their stuff. Solved my issue, for now, at least.

Really hope they don’t do this. I got a lifetime pass for a reason.

2025.18 was released as the public version earlier today. It contains the fix for VOBSUB subtitles. They now direct play on my Pixel 6a.

Plex is performing their normal staged rollout. The update should be available everywhere within a few days.

Can confirm, I’m on .18 and reenabled direct play and stream. Vob sub enabled and it works. Huzzah!
