I have installed Sygic V 15.6.7 on 2 different devices.
One is running Android 4.4.4, the other Android 4.0.4
On the 4.4.4 device Sygic works fine.
However on the other device with Android 4.0.4, when I run sygic, then exit sygic using the 'back' button, when I next launch it Sygic hangs on the initial logo screen until I physically use the 'Apps' setting to force close it, or physically shut down the device.
Has anyone any idea why this might be happening - or how to overcome the issue?
