One of the iPhone's greatest features is its
highly intuitive touch screen.
Unlike other electronic device touch screens,
your iPhone doesn't operate using the blockage of light to decipher which keys
and commands you're pressing.
This makes it a viable choice for cell phone
users who may not be able to complete other types of commands.
While you cannot alter the sensitivity of your
iPhone, you can toggle certain features that make your phone easier to use.
How It Works
The key to understanding the sensitivity level of your
iPhone's touch screen is first understanding how the touch screen actually
works.
Instead of detecting light blockages or heat to interpret
your finger's movements, the iPhone actually has a grid that lies underneath
the surface of the touch screen.
When your finger touches the screen, electrical impulses
detect the area on the grid that you're touching to interpret the letter,
command or motion you're making to issue the correct response.
Screen Sensitivity
While previous models of the iPhone did offer the ability to
change the screen sensitivity and the speed by which your phone responds to
commands, the iPhones 4 and 4S no longer offer the option.
Instead, the touch sensitivity on newer phones is
automatically calibrated for the fastest speeds, which means your phone
responds quickly to your touch.
If this frustrates you and results in commands and calls you
didn't mean to make, locking the screen by pressing the button on the top
right-hand rim of the phone helps stop unwanted commands.
Assistive Touch
Update iPhones running on iOS 5 with an option known as
"AssistiveTouch," which allows users who may not have complete
control over their bodies and motions to use the iPhone.
This program allows you to change the speed at which the
phone responds to your touch.
By tapping the "General" icon, then touching
"Accessibility" and "AssistiveTouch," you'll enter the
assistive touch menu.
When you turn on the option, an overlay appears on the
screen that allows you to give commands by touch, rather than by shaking,
swiping or pinching the screen.
When setting up AssistiveTouch, you'll have the opportunity
to select your command tracking speed, which deals with how sensitive your
iPhone is to your various gestures and custom commands.
Case Issues
Your touch screen isn't the only place where your phone is
sensitive to movements.
Your iPhone has a feature called a proximity sensor.
The role of the proximity sensor is to sense the closeness
of your face during a phone call. When the phone senses that your face is close
to the phone, it locks your screen to prevent you from accidentally activating
the touch screen with your cheek or ear.
This is handy, except when the proximity sensor is partially
obscured by a case and is no longer sensitive to the position of your face.
The proximity sensor is found on the upper right-hand corner
of your screen, so ensure that it remains uncovered to preserve its
sensitivity.

in morning i m downloading a game from installer after that my screen not working
if i split to screen on the half the lower half part dosnt work.. I can se evrything on it but the touch dont work
The lower half of my iphone stopped working (the slide function isn't working) after it fell. I tried reseting it by holding down the home button and the top button but the problem persists.
I have the same problem with my Iphone. The touch screen not working in the lower half near the home button. I could not access the space or shift keys. Its useless because i could not even access to my phone directory and contacts.
touch screen not working,half of the touch screen is not working after it fell
I have been having problems with deadspots in my iphone touchscreen for almost a month now. First various areas didn't work, particularly lower right quad, especially on the keypad. Then, it started going really crazy. It would change screens randomly even though I didn't select them, sometimes entering letters and spaces I didn't touch. sometimes it would just go off like wildfire if I passed my fingers above the keypad -about a centimeter above - though not touching it.
I took it into the Apple store for support. They told me that restoring the phone would update the software and likely fix the problem - which it did. While the phone was restoring, they noted that the phone indicated liquid had entered the liquid sensors. this is true. the phone did get wet about 4 months ago. I put it in a bag of rice for a day or so to be sure there was no water inside and it has worked just fine this whole time.
While they admitted to me that they have seen this same problem in phones that have not been exposed to liquid, they told me they wouldn't warranty it. Fair enough, I understand that.
A couple of weeks later, I started having similar problems. went to the store, another restore and it worked again. although while it was restoring they kept telling me that it was liquid damage. that it can take time to corrode, etc. I don't believe it. had it been within a week or two, I would, but not after 4 months. the moisture would have done it's damage and the corrosion maxed out long before now. but if someone (who doesn't work for Apple) has reason to believe otherwise, I'd be interested in hearing.
now I am having the problem again but on a limited basis, only the very bottom right keys on the keypad are affected. does anyone know of a solution other than the restore thing?
I would love to have someone look inside and tell me whether there is any corrosion.
i am in the half top screen
