I need a phone that I can type a message with. With the 535, it's just a nightmare. Touches don't register nicely ALL the time, even after the update. I repeat. ALL THE TIME. That means you will find difficulty typing in your unlock PIN, user names, passwords, emails addresses, messages, everything every single time. Heck, even the double tap wouldn't work because touches don't register correctly. Imagine having to fight the phone every single time you want to use it.
I owned cheap Android before and at least the touch works.
