Is there a way to tell what DPI setting is selected?

Hi, press DPI switch button and the red light LED indicator will flash. Flash once means DPI at 400; flash twice means dynamic DPI between 400 to 800, flash 3 times means dynamic DPI between 800 to 1500. Thank you for your question!

Does this work with android tablet galaxy 5?

Hi, yes the Pro Fit Ergo Vertical Wireless Trackball could work with android tablet galaxy 5, but it won't be able to program the buttons. Thank you for your question!

What is the polling rate for this mouse?

Hi, the polling rate is 100hz for BT connection and 125hz for 2.4G nano dongle connection. Thank you for your question!

Any ideas on how to strap it to your leg/hip (to be able to control your screens when moving around)?

If you can sew get some Velcro (non sticky back type) and make a strap for your leg, if for your hip, get a material type belt and sew some Velcro to it. Then buy some wide sticky back Velcro industrial type and stick it to the back of the mouse. You can buy both types on Amazon. My mouse kept falling of my easy chair so I got an armrest cover and put some Velcro on that and my mouse. Hope that helps.
