Some Galaxy S7 edge users have been complaining about some touch issues with the display, especially annoying on account of the curved display. The palm rejection option on the edge panel didn't seem to work quite right, and a lot of owners found it hard not to touch and activate something when they were using the phone with one hand.
Thankfully, Samsung noticed those rants, and has issued a firmware update for the Galaxy S7 and S7 edge, coded as build XXU1APD1, that is listed as dealing with the touchscreen algorithms, for a much more pleasant experience.
In addition, the smallish 156 MB update brings about a new button in the camera app that aims to correct shots with distorted perspective. It remains to be seen if the new toggle works as advertised, but obviously Samsung has deemed the issue important enough to warrant a new option, so it's nice to know that it is there.
