These solutions do provide a better listening experience, especially if your using a bluetooth connection.
If you have a bluetooth headset or speaker that support the Aptx codec ( Axon 7 doesnt support this out of the box because ZTE never paid to use it).
For a full featured alternative to Dolby Atmos try Viper4Android
The UI for Viper4Android is nowhere as simple as it was on Dolby Atmos but its uses is far more reaching. TBH i'm not certain there was much effect on the hardware speaker.
Let me guys know if you noticed any improvements.
