This problem was caused by the light through the 2 holes of the glass.You can cut a black tape with 2 holes, and cover it on the sensor flex cable. It can resolve your iPhone 4 Proximity Sensor Not Working problem perfectly.

If the iPhone is still under warranty you can take it to any Apple retail store, reseller or repair shop to get it fixed free of charge. If you are not under warranty however, you can either take it to Apple who will fix it for a fee, or most any phone/electronics repair shop.

How do you fix a red screen on an iphone 5?

Good morning Anonymous

The common thread elsewhere, after going through the rounds of re-start, reset, reload os, etc, is that there is a 'proximity sensor flex' or 'proximity camera flex' cable that is damaged, or broken. See, for instance, here
iPhone 5s red screen iPhone 5s

Depending on how handy you are, there are videos such as
Front Camera Proximity Repair iPhone 5 How to Tutorial that can step you through how to do replacement if this is the case.

Based on every experience I've ever had with Apple or AT&T, they won't even look at the phone - they'll just tell you to buy a new one. You'll likely want to weigh that cost vs. the repair, either yourself or with a local shop. Parts on eBay are plentiful and cheap.

Probably not the best news, but I hope it's useful.

When I push the Phone icon on my 4S there is no number pad?

It could be that your proximity sensor has failed. I have seen this a few times at the apple store. The proximity sensor functions so that you don't cheek dial people while your talking to them. A malfunction will keep the keypad hidden. Hope that helps.

We're is the LCD located in my phone

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.

When im talking on my iphone it keeps muting my calls or putting them on loud speaker is there away to stop this from happening?

It seems that the proximity sensor on your iPhone isn't working properly. The iPhone's screen should turn off when it is close to your face. If this does not happen, bring it into an Apple Store and they should replace it for you. (if your iPhone is still under warranty)

Your proximity sensor sounds like it's not working. It should be a tiny little black dot thing towards the top of the phone. Make sure it's not obstructed or something, then I'd check your settings to make sure you haven't changed it to not turn of the screen. Else the proximity sensor might just be broken.

IPhone screen will NOT go blank during calls

Sorry but your proximity sensor needs replacement. Take it to the apple store and see if they'll give you a replacement. If they don't there are third party iPhone Repair Services that can fix it for you. There are also free iPhone Repair guide that show you how to fix it yourself.

Iphone screen is black

Do you have a protective screen cover on the phone, if you do, you may have covered the proximity sensor at the top. MOst screen protectors cover the sensor causing them to turn off the screen during a call and not allowing it to come back on.

If you do have one on, take it off and try it without.

If this is the case, a Belkin screen protector tends to be the best one because it has the proximity sensor cut out of the plastic

Hope this helps

Iphone Screen not lighting up

If you are using a case, the iPhone 3G and original iPhone cases are not compatible, so it may be covering the proximity sensor. If you have a case or something else on the phone, try taking it off. When the proximity sensor detects something covering it, the screen will go off to help preserve battery life (such as when the phone is up to your face) however if a case is covering it, it will assume that it still needs to be off.
