Try the following steps with any media player on your device. If the data is on the SD card, copy the file to the device's memory. Then try to play the data. Please note that it is best to use only Mp4 data as a movie. Otherwise there is an alternative with Libertine and the Kodi Mediacenter with effort. You can also try the hint with audio data.

@Lakotaubp said in UT on Nexus 5: File System Stuck As Read Only?: That [version of uTouch available here on RC channel] will be the new [OTA13] stable channel [version] anyway soon. Just to clarify ^^ RC remains RC, and when OTA13 is out, jump back to stable channel.

@arubislander said in Best file system format for Micro SD Card with Ubuntu Touch?: @Opolork Out of the box UT also expects the file system on the card to be FAT32 tot be able to automount it. Any other filesystem and you will need to automount it manually after every reboot. I see, thank you, arubislander. No change required so.
