ronw:I do not understand the reasoning behind not updating to a newer phone. If money is the problem there are plenty of newer phones like Nokia 1.3 for $100 runs Android 10 and works well. Stop expecting everyone to support years old Android 4 or 5 phones and hope they will much use today. upgrade
The point of the app isn't to support a bunch of technology-savvy geeks who buy a new phone every six months, it's to support as many people as possible. Just because it can be made to work, with some effort, for GZ people who are about five standard deviations away from normal doesn't mean it works well for anyone else. In particular, the most at-risk demographic is the one who'll be running the cheapest possible Android 4 phone that one of their children talked them into getting.
