how can i type perfextly using android pjone?

Maybe you need a bigger phone so the keyboard will be bigger. I had a phone with a 3.5 inch screen and I was always pressing the wrong letters. I upgraded to a phone with a 4.5 inch screen (Tracfone LG Ultimate 2) and now I mosr=tly hit the correct letters.

Also if you turn your phone sideways you get a bigger keyboard but less room to see what you are typing.

Use predictive text and autocorrect, as long as you're not using slang then those features will work. If you use slang and text speak then it is just a matter of getting used to it.
