Sadly TeamViewer is the only thing that works on old Android Point-of-Sale devices which are still numerous. And since Android requires the manufacturer signature to do screen sharing on older versions and those manufacturers are either dead or too big to care, it will remain to be so. I can't wait though for the day the place I work for decides to drop support for them and stops paying for that... thing as it's not only extremely expensive and awful from a security perspective but also from a general quality one: some days their server just decides to not log you in, they have a nasty crashing bug that often happens when you resize your meeting window that has been there literally for years, among other things.
