Build 3.522: Loss of scree resolution when installing to mobile device

After upgrading to Cybertracker 3.522 and installing application to mobile device (Samsung Galaxy Tab Active 2 Tablet) the words of the application look all pixelated and fuzzy in the tablet. This was not the case with previous Cybertracker version 3.514. Tried different screen sizes but the outcome is the same. Any idea as to why this might be?
Thank you for your help.
All the best,
