A part of my iPhone's touchscreen isn't working anymore! Solved/Closed

Question

Hello,

I just dropped my iPhone on the ground, fortunately nothing serious, the screen is not damaged, just a few scratches on the case. However, there's a big problem: I can't unlock my iPhone, the bar is not responding, and neither is the entire touchscreen. It's impossible to access any application!! My touchscreen only responds when I want to turn it off with the menu bar "turn off"!! I've tried everything: turning it off and then turning it back on normally, reloading it by pressing the home button and the lock button simultaneously. I haven't removed the battery and I don't know how to do it, could that solve my problem?

Please help me, I'm lost!!Configuration: Windows XP Internet Explorer 6.0

Hello everyone,

I had exactly the same problem:

My iPhone took a little fall, nothing too serious, but the touchscreen no longer works...
After a restart, I can't tap "unlock" to enter my PIN.
However, the rest of the touchscreen works.

The worst part is that the touchscreen part of "unlock" doesn't work; but when I go to "Emergency Calls" and press the keys on the keypad that are at the same height as the "unlock" button, it works there!!!
---> The touchscreen is therefore not defective

I thought it was a software problem, and I performed a complete restore to 3.01
This didn’t fix anything. Still the same problem, can't unlock the SIM.
The "unlock" button doesn't work, while the rest of the touchscreen does...
---> So it’s not a software problem

Then I remembered that the iPhone has a sensor in the upper left that disables the touchscreen when you bring it close to your ear. I have a feeling that this sensor is defective due to the fall.

So I turned off the iPhone for the umpteenth time. I tapped the area at the upper left near the ear sensor several times. I restarted the iPhone and "HooôÔôoo Miracle" it works perfectly again.

It was the ear sensor that was causing the problem!!!

You can try the following experiment: If you cover the sensor at the upper left, you will see that most of the touchscreen functions of your iPhone are disabled (even without being on a call)

I hope this tip can help you if you encounter problems with the touchscreen.

See you!

You can't remove the battery from an iPhone... without completely dismantling the thing (Apple has brilliant ideas sometimes)...
But if turning it off and on again doesn't change anything... removing the battery wouldn't have probably changed anything either...
You can unlock the iPhone so the screen is fine in terms of the bar.
You reach the "Desktop," I suppose... if you try to touch the screen (to change pages) where the bar is, does it work?

I can't unlock it, be careful! Let's proceed step by step:

1) I turn it on without any problem
2) it displays the menu
3) Then comes the message "SIM card locked, OK or unlock" and that's where the problem is: I can't press the "OK" or "unlock" button or even change the page, everything is frozen!
4) When the iPhone goes to sleep, I unlock it with the top button but I can't slide the "unlock" slider from the lock screen.

Do you see where this could come from?

wsl1912 · Answer

It's bad... it looks like your iPhone's screen has lost its sensitivity... The fall must have damaged something inside... Is it still under warranty?

Bertboss · Answer

Unfortunately not, I bought it used on eBay six months ago but without a warranty... As for the sensitivity of my screen, it works because I can slide the "turn off" cursor, but it's true that it’s serious and I’m scared. Is there a possible solution I could try?  I’m waiting for help from others to assist me. If you have another idea WSL1912?  Please.

wsl1912 · Answer

If you have nothing to lose, you can attempt a restore using the iTunes software (if it can detect your iPhone)... but I fear you might lose your data... Maybe there are websites offering iPhone repairs (I seem to have heard rumors about this)  -- "Faster, Mr. P, the Angels don’t like big clumsy ones..."

DuC · Answer

Hello,  It seems to me that the touch sensors between the edge of your iPhone and the screen have been touched, at least those at the bottom of the screen. If you feel capable, replace them by carefully disassembling your device. They are sold on spare parts websites for iPhones, you can find them via Google.  There you go.

Bertboss · Answer

Ok WSL1912, I'm going to try with iTunes, you never know. But I think DUC is right and that my bottom touch sensors are damaged. I can still turn off my iPhone with the top bar, but the remaining two-thirds of the screen don't respond anymore. Ouch, I'm not too sure about this thing. Can the people at Orange repair it for me, or does it have to go through Apple given the complexity of the thing lol?

wsl1912 · Answer

Orange? No... don't repair them... at best they'll send the precious back to Apple... Better to try Apple.  -- "Faster, Mr. P, the Angels don’t like big clumsy ones..."

DuC · Answer

It's better via Apple, but you can find people in small telecom shops or individuals who are good with electronics and can do it for you. I believe, from what I've heard, there's only one type of ribbon to connect; the longest part is the proper disassembly!

Bertboss · Answer

Sure, thanks for the information DUC! However, if anyone else has suggestions for potential solutions, I'm open to them lol!!  Please!

tu ne pourras jamais enlever la batterie, c'est la seule chose que je peux te dire à part ça désolé.

noit · Answer

it's a mess this bug, it's enough to make you lose your mind when all you need to do is make a call!!!!!!!!!!

Tifortune · Answer

Yes, the battery is removable ^^  You just have to open the iPhone carefully, remove the warranty sticker (the warranty is then void ...) and then remove 3/4 screws ... and then you can see the battery ^^  After that, I think Apple support won't do anything since the iPhone is equipped with a shock detector. Orange just sends the devices to Apple in case of problems  But you can always check in a store and ask for a replacement; sometimes it doesn't go to repair and the exchange happens without opening the device.  Changing a screen is expensive: €130 for the original screen of the iPhone 3G/3Gs; that's quite a lot. Changing the sensors afterwards is possible ... it also voids the warranty and it's risky ...

laure82 · Answer

Hello, little iPhone accident yesterday, ouch

After going to Orange, calling them, and calling Apple who can't do anything because it's out of warranty, I took a look online and what do I see? :D I tapped my iPhone and it seems to be working, so I'm crossing my fingers that it continues to work and I'm going to go get it a padded case, lol

Thanks everyone!

Hello, I have the "old" iPhone and so there is no little sensor, I really don't know what to do, I need your help!!! Thank you so much!!!!!!!

jeremy · Answer

Hello, I'm having the same problem here with the first generation iPhone. Where are the sensors exactly, if there are any? If not, what should I do? I've restarted it dozens of times without success and rebooted it once again without success. Thank you in advance, this is urgent.

Tifortune · Answer

The sensor is located next to the brightness sensor; above the screen, to the left of the "speaker"
Put the iPhone 10cm from a halogen lamp and you will see it will appear (it will be purple/brown while the part without the sensor will remain black) ;)

PS: Don't stay too long under the halogen, it heats up quickly ^^

Tifortune · Answer

The sensors are to the left of the top speaker of the screen!

Turn on a desk halogen lamp and place the top of the iPhone 5cm from the lamp, you will see them appear =p
(DON'T STAY UNDER IT FOR TOO LONG, it gets hot)

Then, try the tapping method...

Franck · Answer

I have already experienced this, and it went away by itself in large letters, and once turned on, you need to go to the settings configuration, then general, and finally at the bottom of the drop-down menu touch accessibility and make sure the ZOOM function is set to NO, and then restart it.

impossible to remove the battery. I had this problem but worse, I activated the alarm normally, then this BUG occurred, now my iPhone never stops ringing, I can't turn it off or unlock it.

rstone · Answer

Hello, this happened to me,  after checking the forum, I tapped it, it works for 5 minutes but partially Then I understood that it's a connectivity issue: I disassembled the phone, completely disconnected the screen, blew a little everywhere (be careful not to let any moisture in) and reconnected everything. And bingo!!!! it works!  Be careful, you can use tweezers to connect the wires.  rstone10

Hello, my iPhone's touchscreen no longer responds. I turned it off using both buttons at the same time but nothing happened, I also restored it and nothing worked, and it keeps giving me that damn message "insert a valid and unlocked SIM card to use the iPhone."  Please, can someone help me? I need it for work..... boohoo  Should I wait until the battery is dead?   Thanks in advance.

For those who have an iPod Touch, I simply reset it twice, and then it worked normally.

Bazarissme · Answer

Hello, my problem is similar to yours. I broke my Home button some time ago, and I replaced it today. When the restart happens after complete reassembly, HORROR, there is no response from the touchscreen, even after a hard reboot. I reconnected everything 3 times, but nothing works.  Any ideas?  Thank you in advance.

Josephinewlrd · Answer

I have exactly the same problem; my iPhone 3G fell to the ground and since then the screen is locked, I can't even unlock it since I had set a security code on it. The home button works but the top button barely does, and that’s been the case for a while. So I can't unlock it with the bar, enter the unlock code, or turn it off. I've tried connecting it to iTunes but I can't do anything if the iPhone isn’t unlocked... And I didn't quite understand the story about the sensor with the ear! :( Can you please help me?

Rayanne26 · Answer

Hello, since yesterday I've had the same kind of problem. I can play music and everything, but the unlock slider at the bottom of the screen is not responding anymore. I can turn it off a million times but it doesn't work. Otherwise, the top part works. After all the manipulations you've mentioned, I'm still without results. Help please! I have an iPhone 2G.  Thank you.

wiloubi98 · Answer

Hello, I had the same problem. So I opened the iPhone, unplugged the cables, lifted the glass, then I cleaned it. I then put everything back together and miracle!! It worked again!! :)

Sylvain tlm · Answer

If it were a sensor problem, you wouldn't be able to see anything; the screen would be black like when you make a call.
