Have you noticed that you have to repeatedly tap on your Samsung Galaxy S8 app icons just to get them to open? isn’t that annoying?  I initially thought it was a screen sensitivity issue or something, but I dug deep and found out that the culprit is the icon frames that have rounded corners by default.  When I went into settings and then > Display and then > Icon Frames option–I was able to change that to  “icons only” and voila I no longer experience the issue of apps not opening when I tap on them.  This issue may or may not be present in other carrier S8 like Verizon, Sprint or AT&T, but it is present in T-Mobile S8.
