You can't use a case with this thing. Everyone I know puts their handy in a case. There's even a joke about it (https://www.theonion.com/man-taking-phone-out-of-case-for-first-time-in-years-st-1819592785). I drop my handy a few times a week. What's that going to look like?
I have three cases I use with this depending on circumstances, and they have all worked very well. I recommend an OhSnap 3.0 phone grip as well to help with the weight and to allow use of magnetic chargers and stands.
120Hz PWM. Great. Another cool phone I can't use.
