Nokia :: E52 / T9 Typing Lag

I am having some problems with my e52 typing sms in t9. I have been using t9 nokia for many years and many previous models, but the e52 seems to be unable to detect my typing fast enough. I am very sure that i press the keys with a definite click but sometimes its just cant detect when i type fast.As a business phone it is important to have very smooth and efficient typing. It is the most important function 2nd to calling.for e52 users u can do a test in T9 typing by like entering words like 963 for YOU fast (but ensure that u get a click out of button) most of the times only two characters appear.Is this just my e52?I hope that u can provide a firmware update for this.
