Not sure if it is still ok to add some things to this post, but there are a couple of things I've noticed as I keep working with Ubuntu Touch. Again, this is mostly on the "nice to have side."
- Lock Screen Widgets
I play a lot of music on my phone, but everytime I need to change something, I have to unlock the screen. Having a quick way to play/pause, change tracks, etc. would be nice. Other widgets could be weather, etc.
- Music Organization (More app specific)
Music is incorrectly organized. Search by artist and two artists have the same album name, the songs are grouped togeter. It looks like it groups on Artist Name, Album, or Song without any "keys."
- Hardware Docking stations
Not sure about other phones, but I can't use a hardware dock with mine to turn it into a computer.
- Sharing Libraries between Waydroid and Ubuntu Touch
Often times, I need to send a picture or download a picture in one OS and do something with the picture in another OS. Having an easy to find "Shared" folder between OS's and having folders that aren't shared could help with this scenario. I'm fine with transferring by USB if I need to. I can understand if this is not recommended for any security issues.
- Safely Remove USB
Sometimes the USB Drive can be safely removed...others times it can't. It gives an Unmount Error. It is kind of inconsistant.
- Volume too loud message
I play music via AUX in my car. The volume on the phone is all the way up on the phone, but the volume in the car controls how loud or soft I want to hear the music. The message gives me a Volume Too Loud message with an OK or cancel. Sometimes when I hit OK it seems like I can't toggle the volume on the phone. Due to this, the fidelity is not as good.
- Music File Formats
The music player can't read ALAC. Some people transferring these file formats would need to look at other formats to play the music.
