Improve contrast of user interface

You do lots of clever stuff but what i find annoying is that the basic info to operate on phone is faint and not clear. Could do with much stronger contrast and maybe larger symbols.

Is not so bad at home but when out in sunlight etc very difficult to read.

I can drive a race car at 150mph but struggle to see your home tab etc. I am using a recent spec Samsung and have no difficulty with any other software.

Not clear when sensors linked up. Not easy to switch off etc
