Hi,
A new version on Android with a better save and export compatibility with many cell and tablet.
Some phone need to add permission manually. Setting-> App -> Tile2Map -> permissions and enable storage.
I test it on some phone and it’s work great:
LG G3 (android 6.0
Samsung Galaxy s7 edge (android 6.0.1)
Asus Zenfone 2 Laser (android 6.0.1)
Acer iconia 7 (android 4.4.4)
Chinese model UM-A75 with a20 cpu (android 4.2.2)
have fun
