Umidigi bison gt 2 is a rugged 4g phone with 8gb+128 gb internal storage. Works well on mint mobile (which uses the t-mobile network) using lte frequencies.

Its not a flagship phone, but its pretty solid. The fingerprint sensor seems to work better than many other budget phone's fingerprint sensors. Seem to work flawlessly.

The on and off behavior has no relation to touching the screen or *. The additional shortcut * make it difficult to pick up the phone with out opening apps by mistake. Swapped cables with their charger, still no electrons.

Then when i tried to make simple phone calls, or facetimes, the people say they could barely hear me.
