Currently using it. Not much difference from the previous version of 2.23.
Anyways, here are some of my opinions about it:
Certain things I like about it:
- Many SQ presets to choose from
- Battery drains by a segment after 14 hours of usage on User 1 (my own SQ preset) at lvl 30(10hrs w portable speaker and 25(4 hrs w earpiece) volume along with 20 brightness
- Extremely light weight
- Reasonable big screen
- Sharp and bright display
- Smooth scrolling in and out of folders
- Very fast boot up on pressing the power button (about 2 seconds)
Certain things I do not like about it:
- Even though selecting Non-European region, the volume is still quite soft
- Not much video formats supported
- No delete option to remove audio/videos (WTF?)
- The software bundled with it does not encode the video properly, audio doesn't sync with the video
Hope it helps potential buyers getting the J3.
