KNOWN PROBLEMS:
* Doesn't count properly usage on Samsung Galaxy S5 LTE-A (SM-G906S and SM-G901F) with Android 5.0 Lollipop. Please contact us for a refund, or if you want to help us to fix this problem.
* On Android 5.0+ the "Disable mobile network" function does not work (the mobile data switch widget and the auto-disable feature are both affected). This is because on Lollipop the enable/disable function is no longer accessible to third-party apps.
* Doesn't count properly global usage on Samsung Galaxy Tab 10.1 and 8.9 - this problem affects other data counting applications as well and is caused by a bug on the tablet itself. You may try to check the "Calculate global usage from usage by app" advanced option as a possible workaround (feedback welcome).
* Doesn't count properly global mobile usage on Samsung Galaxy R / Z (i9103) and possibly Galaxy Y. Problems were also reported with the Captivate Glide. Same workaround as for the Galaxy Tab (see above).
