We have a plan to distribute Android tablets remote sales personnel and we want to have very limited functionality in the tablet itself.
I have tested the kiosk mode (both MerakiKiosk and Samsung Knox), but there are some problems. Since we have Samsung tablets, the Samsung Knox was my first thought, but there you can only have one app opened & nothing else (I don't know why you have whitelisted/black listed apps in the profile configuration, when you only can have one app opened on screen). So then I tried the MerakiKiosk mode and was able to have the required apps installed and shown in the kiosk mode window. Now the problem is, that after installing the kiosk profile, users cannot access anything outside the kiosk window, which means they cannot even connect to different WiFi networks (not allowed and no option to allow it). So this becomes a problem when the sales stuff is traveling
Right now it seems that the only option would be to have the tablet configured without kiosk mode and restrict access to only certain allowed apps. The goal was to make it super simple for users, so that they would only see the kiosk screen and nothing else.
There are a lot more options to configure with iOS devices, but not so much for android...
