I've recently switched from my iPhone 3GS to this HTC Evo Design 4G (4.0.3) because I get free service on the latter phone, and my setup is coming together nicely for the most part, but I have one huge stumbling block: the keyboard.
I've used iOS for ~6 years and I figured the new keyboard would take some getting used to, but I just can't type quickly on any Android keyboard I've tried (stock, Google Keyboard, Perfect Keyboard, etc) because it physically won't let me. It's unable to handle inputs in quick succession. To test this, I tried typing 'a' and 'h' alternating very quickly on each device. On the iPhone the result is "ahahahahahahahahahahaha", but on my Evo it's "ahhhhhhhhhahhhhhh". Elsewhere, input on the device is fairly snappy.
Any suggestions? I've tried Googling the issue with no luck. I type quite a bit and it's driving me nuts that I have to slow down for it to recognize all my inputs!
