Ugh...I was so excited there...but it seems the app is optimized just as poorly for my phone as every other mobile wallet I've tried using.
Here are some screenshots I captured just now...This same exact behavior occurred when I've tried TX wallet, GAIA wallet, and countless others.
My phone is a LG G3 D850, have had the same errors on Kit Kat & Lollipop (which I'm using now)
Landscape mode doesn't fix the problem either.
