what do you mean different brand? You mean a different brand completely or are there different brands of xtremeguard? I only saw one on their site and went with that one. Hope I don't get the unresponsive issue someone else had, I'll be sure to lightly spray with water & hope to avoid that
I am pretty sure that the main "issue" with responsiveness is trying to use it too early. If you install it, make sure to get as much of the bubble out while it is still wet ans then LET IT SET UNDISTURBED FOR 24 HRS before turning it on, you will not see any issues with responsiveness. There may still be a few small bubbles after 24 hrs, but they should go away completely over the next 1-2 days.
I have done TONS of these types of "wet screen protector" applications, and this has been my experience consistently.
Do NOT use less water! That is a recipe for bad installation as well. Use enough water so that the screen protector will "glide" easily on the screen when you first apply it. This will help get it positioned right, and will also help you get most bubbles out easily.
Use a credit card or a hard plastic card to squeeze out as many bubbles and excess water as you can WITHIN THE FIRST 15 MIN of installation. Then they get much harder to get out.
But if you keep the device turned OFF for the first 24 hrs, responsiveness should not be any issue.
Good luck !
