Will PPSSPP work fine on Galaxy S6? (thread adjusted for rules)

[Pillidge]

(thread fixed because the last one broke piracy rules, sorry about that, I just really want an answer to this)

I'm getting Samsung Galaxy S6 soon, and I'm wondering if I will be able to install PPSSPP on the device without any error or issue or warranty void whatsoever, without having to jailbreak or unlock my device in any way. Also, with the graphical settings at the lowest, will most games run at a respectable framerate?

In a nutshell, can I walk out of the store with the device, go home, charge it up, install PPSSPP, adjust the settings, and play right away, preferably in that order?
