My iPhone 4 sensor doesn't work?

I change my iPhone 4 screen and I found that the sensor doesn't work what I do

If you have a case on the iphone, remove and see if that helps.
If reset, restore do not solve, then make an appointment at the genius bar or call Apple Support to arrange for a replacement.

Proximity Sensor Doesn´t Work. How to fix it?

I´am experiencieng a problem that many other iphone users may either.
The proximity sensor doesn´t work. When i answer a phone call, the display doesn´t turn off, and everytime i keep dialing numbers, endind calls and a lot of other little things that are getting on my nerves.
It seems apple couldn´r care less for those problems we are having, and nothing has been told or done. Thats good for us to see how much apple is concerned with customers.
Anyway, is there a way to fix this annoying thing???

this could be a few reasons,
1. try and update the device to the latest firmware via itunes, to check you on are on 4.3 go to settings>general>about and under version, if is lower than 4.3, update the device
2. if this fails remove any cases or screen protecters (silly, i know) that may block the sensor
3. if that fails, take to the nearest apple store, and describe your problem, they will either replace a=or repair
hope this helps

Settings>Store...tap the ID shown...sign out...sign back in with the ID you want to use.
Note: Apps are forever tied to the Apple ID used to originally obtain them. They cannot be updated using any other Apple ID other than the one they were originally obtained with.

My accelerometer(gravity sensor) doesn't work

my ipod touch 4 accelerometer(gravity sensor) doesn't work, it has no response when i play games, watch video or photos,browsing web.....i update and restore many times...but still doesn't work...
also,once i lock the ipod,it can't be unlock and remains black screen. I need to press the power and home button together in order to force in re-open again...

I would try in order:
- Reset your iPod. From your description you may have already tried that.
-Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Restore the iPod from backup via iTunes on your comnputer
- Restore your iPod to factory defaults/new iPod via iTunes
- Make an appointment at the Genius Bar of an Apple store since you may have a hardware problem.

Iphone 4s suddenly doesn't work.

iphone 4s suddenly doesn't work. "Slide to unlock"doesn't work. Touch screen doesn't work,power switch doesn't work.screen still black,call incoming work but can't received. Anyone have a solution to this or why this happened? please answer me

Why do you ask? Do you think you were fired and don't know it yet?
No, they can't just 'turn it off'. They can not control whether it will power on or not.
Since it's a corporate device. Take it in and have your help desk/IT department look at it.

I had a problem my iphone 4 mouthpiece doesn't work when i am calling other mobile phone

i had a problem my iphone 4 mouthpiece doesn't work, when i am calling other mobile phone they can't hear me but i can hear them. But when I am using the skype and viber to talk to other people they can hear me perfectly. and also when I record my voice it sounds good i can hear my voice.. i dont know what is wrong with my phone?

I get trying to unlock it and it finally accepted the 4 digit PIN number on my SIM Card, which it wasnt accepting before (there is also a super PIN number, which i dont know whats for). And now it says "no service". I am reseting the phone and sometimes it just says "no service" and other times the SIM Card is locked again and it doesn't accept the PIN number anymore...

Well if you restore your iPad that might work. If its a software issue, it might solve it. If that doesn't work, it might be a hardware issue that apple can fix.

How do I retrieve text messages from a iPhone 4S that doesn't work anymore?

How do I retrieve text messages from a iPhone 4S that doesn't work anymore?

If the phone isn't working, you can't. If you have a backup on your computer, you may be able to extract them from the backup using 3rd party software such as iPhone Backup Extractor (see http://www.iphonebackupextractor.com).

My proximity sensor doesn't work anymore while calling... How do I fix this?

The proximity sensor of my iphone 5S doesn't work anymore. Therefore my screen just stays on while I'm on the phone and every time my face touches the screen I pauze the conversation, or mute it, or...
Does anyone know how to fix this?

Try removing your case. If still an issue, take it in to Apple. You have a 1 year warranty.

Major advice needed with ATT / IPHONE / MICROCELL misleading/doesn't work

I'm sorry if this is a little off topic, but I need some advice.
I've been battling ATT since thanksgiving week. I moved into a house (checked the coverage map before moving, and saw I was in the clear)
I have no service here. NOTHING. I had to use a verizon phone to call them, since Verizon actually works. They tell me they're working on it... weeks go by. A month, and another month of calling them and wondering what they could actually be doing to rectify my problem. Well about 2 weeks ago, ATT's RF engineer was hanging around my house for a couple of days. He told me they didn't even notify him about my problem until days before he arrived! So they were lying to me the whole time about trying to fix my lack of service. I kept asking them, "Can't you lend me a microcell until you fix what's wrong here?" They just said "No, you have to buy that and pay for it's service."
So it's now Feb 25th, and it's day II with my microcell. It shows 5 bars, but most of my calls are dropped, or I'm talking to someone that can't hear me. I emailed them last night asking if I could just be let go from this contract so I can move on and get back to business. They will waive my fee if I give them my Iphone 4 which I've owned for 11 months. Doesn't this seem a little strange??
I mentioned how I've lost many clients and a lot of money due to the fact that they think I'm ducking their calls because I don't receive them unless I drive 2 miles from where I live.
Again, today I talked with the service rep and they will not budge. Is there something in the contract that would help me out? Even the RF engineer/tech told me there is nothing they can do (other than putting up more towers!)
So I'm stuck in this nightmare with a phone that doesn't work, and paying for it. I still have a year on my contract and I just want out. The iphone was fun and all but I'm done with att and their ransom fees.
Can someone help me?
Again...sorry if this isn't specifically an apple related post, but I don't know of another reputable place to ask advice

As you know, this is a user-ro-user iPhone tech support site. Neither Apple or AT&T participate here. The only way you can resolve your reception and service issues is through AT&T - no one here could possibly fix this. AT&T does provide free MicroCell service in some known poor coverage areas.
You can try some basic troubleshooting steps as described in the User Guide - Restart, Reset, Restore - but I doubt there is a problem in the phone itself.
IF you're not getting anywhere with AT&T, file a complaint with the FCC. Did the AT&T coverage map showed coverage in your area before you purchased the phone? You might want to get a lawyer to help.
