The upcoming Ulefone Future model just received another extra function with the System UI Tuner for Android 6.0 Marshmallow, which should allow the users to tweak a bit the UI.
Nothing major, but still a handy little option to customize your phone a bit more.
System UI Tuner is not going to be turned on by default and you need to activate it in the Settings manually.
Then you will have the chance to change the top and bottom notification bars to your desire, shuffling the icons and functions just as you like.You can check out the following video about the setting up and using the System UI Tuner.
Ulefone Future is currently on sale for $239.99 for example here.
