I know how u feel on that. I am always having the typo issue. But I've yet to use a kb app, not saying its not a good idea, just that I haven't used one.
I have to ask, do you have a case on your phone? I have an otterbix that has a screen protector on it, and I was using another screen protector under that. It was giving me similar issues to yours. I removed the screen protector, leaving the otter box protector, and it helped some. My phone does work great naked though. But that's not an option because I don't want to risk damage to my phone, or scratches on my screen.
Imho they should have a screen sensitivity setting. Also found that keeping my screen clean, helps....
I feel your pain, the double and tripple tap.... is getting very very old. I'm upgrading to the maxx and a slew if new problems tomorrow.... I hope not, keeping my fingers crossed!!!
