Re: n900 touch screen problem!!!
 
This happens over and over with nokia devices (770, N800, N810, N900). I had a problem with 770 and N810.
I think the main issue is the resistive technology. It was simply not meant for so much swyping and other finger dragging gestures.

Initially they were intended for point interaction, but someday some clever software developer invented thumb-friendly operation. Actually the wanted to emulate a iFruity which did have proper technology behind it.

It basically means that areas of the screen are systematically pressured, and the thin film becomes less uniform sooner or later. At the same time, covering plastics is deformed as well over time.

Can you specify what is your general use pattern?
Do you use stylus at all?

is there a way for calibrating the pressure sensitivity in areas?
I ask because in the MyPaint program the screen is more sensitive in certain areas (in general less sensitive at margins)... I also use screen-protector.

ok guys i had the same problem as most of u .
here is what i did and how it worked .
i brought hair dryer pointed it to my n900
make sure some heat reach the phone , but dont overdo it and melt ur phone , make sure u remove battery and cover , and when u feel that the phone became hot , place ur batteries and turn it on , thats how it worked for me ^^

Big deal with screen protectors here is they are not made to be used for a lifetime. Like any other plastic materials they shrink in size with constant heat and when it does the film of a resistive screen phone becomes strained.

once my phone cools down after the heating it reverts back to the same sporatic activity. after i heat it up with the hair dryer it works again. this is quiet rediculous. anyone have any permanent solutions to this?

hmmmm , mine never reverted .
and i figured out the reason why this happened.
when i went to gym i put my n900 in my sweaty pocket , it must absorbed some of the sweat , and when i heated it with hair dryer the sweat must evaporated .
this happened again when i put it in my bag with my sweaty clothes as well , so maybe u r doing something daily that causes this to happen

i do go to the gym alot and have my phone in my sweaty pockets and sometimes i sit in the sauna and listen to music which could also be one of the reasons this happens, if i set it in a bowl of rice overnight and stop taking it to the gym could that possibly stop my problem?

A day ago i reflashed my N900 and i got some uninvited,extra,touch screen problems related shortcuts ( email,photos,phone etc) .
,they dont even give me an option to cross them on the desktop so they dont come again,so that means i can open them but cant cross(close) them.And because of these shortcuts i cant cross (close) an app immediately cuz these shortcuts show up on the cross,most of the time i have to pinch my fingertip a little hard to get a response from the screen. i really want to get rid of them.what do i do ?help please
