Sorry for reposting this, I put it in the wrong place.
Alcatel pixi 3 (7) tablet
Android version 4.4.2
Kernel version 3.4.67
build number 01001
But it works fine on alcatel pixi 3 smartphone which was purchased as a bundle from tesco last week
Custom build version 01002
When I check the store it says "the app is compatible with some of your devices"
Phone - 02 tcl 4013x works
Tablet - no carrier tcl 8055 - doesn't work
It doesn't work on a Nexus 7 so my guess is it's not designed for Tablets.
