The android app is pretty much as the IOS app. But the IOS one is more polish. There are some things that make it better, like the UI.

One of these is the fact that the music player go on full screen on IOS but not on Android. The bottom and top part of it isn’t as the same color as the player.
Look at the difference between the IOS and Android app : 

I hope that the Deezer team will find a way to deal with this problem

IOS :

Android :

The full screen problem gives a feeling of an old app that hasn’t been update since a long time.
Spotify finds a way to extend to the top of the screen (but not the bottom. Maybe because their player is scrollable) : 

And the YT music app have found a way to go full screen 

I hope that the Deezer team will find a way to deal with this. I know that’s a problem that have been reported years ago, but I hope that this time Deezer will listen. Also, I already told about this in the idea channel but nothing change. 

Update : 
I noticed that the is some pages of the app that are in full screen, such as albums and loved song.

We can see that the bottom part has no black line and the top also. It’s much more beautifull. And the player go in full screen when i open it in these pages.

The top part stays black unfortunately but when opening the player the back part start to be the good color but finish black (screen during opening of the player from a full screen album page) : 

It’s not a big thing to do, but it’s a nice way to push the app further and make it even more perfect ! Also, I heard that android will force app to be full screen, so I hope that Deezer will understand that problem and solve it !

Good luck Deezer team, continue to develop the best music app !
