Q: 4. my phone including protective case is 5-7/8" tall i.e. just a tad taller than RAM-HOL-PD4-238A max height of 5.75" but barely meet min height of the 238AU. Which one should I get?

A: I recommend you get the RAM MOUNTS RAM Quick-Grip XL Smartphone Holder with Ball Mount BH #RAHOLPD4238U, as you can use it with a thicker case if needed, and in case you upgrade your phone to a bigger phone. On the RAM-HOL-PD4-238A, you would have to use it without a case since with your current case it is a tad bigger than the maximum height of the product.
