Hi Anthony,

The meter needs Android 4.4 or later, sorry. So the Samsung with 4.0 won’t work.

One of the inexpensive test phones I use is this: http://www.amazon.com/gp/product/B00ZVI4BJW?psc=1&redirect=true&ref_=oh_aui_detailpage_o04_s00

I hope it’s useful to you.

We do not support windows phone now, sorry.

Best
