iPhone 4S glass is shattered ¶ 

Oh no! Your iPhone's glass did not survive your unintentional drop test!

Broken front panel ¶ 

Take a deep breath and see if your iPhone will turn on and operate normally. In most cases, the iPhone is still functional but now a cosmetic disaster. Unfortunately, the iPhone 4S' front glass and LCD are fused together and must be replaced as one piece.

Broken rear panel ¶ 

Apple did not grace the rear panel of the iPhone 4S with the same high-strength glass as the front, so fractures are much easier to come by on the backside. If your rear panel is smashed, you must replace it with a new one. Before attempting this repair, though, make sure you have the correct screwdriver.

iPhone is frozen or unresponsive ¶ 

Even after furious button mashing and screen smashing, your iPhone 4S doesn't respond.

Restart iPhone ¶ 

Sometimes all it takes is a restart for the iPhone to become responsive again. To restart your iPhone when it is unresponsive, press and hold the sleep/wake and home buttons until the Apple logo appears (~10 seconds).

Very low battery ¶ 

It is possible for an iPhone to become unresponsive if the battery drops to an extremely low level. Plug the iPhone into your computer or wall charger and allow it to charge for at least 20 minutes before using it again.

iPhone 4S will not charge ¶ 

Plugging in your iPhone 4S does not bring it life.

Bad cable connection ¶ 

Check the USB cable for damage and dirt, especially at the ends. Then try using the wall charger, as this will provide greater power input than the computer/USB.

Broken charger or USB cord ¶ 

Try using different chargers to see if you may have a problem with your charger or cord.

Obstructed/bad dock connector ¶ 

Inspect the 30-pin dock connector at the bottom of the iPhone for dirt, lint, and damaged pins. Clean out the dock connector very carefully with a tooth pick or soft toothbrush. If the dock connector is broken, you will have to replace it.

iPhone will not turn on ¶ 

You cannot get your beloved iPhone 4S to turn on.

Drained/dead battery ¶ 

Plug your iPhone into your computer or wall adapter to charge. If it does not charge when connected to either of these, you probably have a dead battery. The battery will need to be replaced with a new one.

Bad display ¶ 

It is possible that it appears nothing is happening because the display is bad. If the iPhone sounds like it is working properly but nothing is visible, it is possible the display is bad and must be replaced. Unfortunately, the LCD and glass panel are fused together, and must be replaced as one unit.

Bad logic board ¶ 

If nothing else works, your logic board is probably bad and needs to be replaced.

"This accessory is not optimized for this iPhone" message ¶ 

An error message appears as if you have connected an unsupported accessory to your iPhone

Obstructed/bad dock connector ¶ 

Check the 30-pin dock connector at the bottom of the iPhone for dirt, lint, and damaged pins. Clean out the dock connector very carefully with a tooth pick or soft toothbrush. High concentration isopropyl alcohol (at least 90%) and a cotton swab should be used to clean any debris that does not come off with a tooth pick or soft toothbrush. If the dock connector is broken, you will have to replace it.

Dirty or corroded logic board connections ¶ 

After an iPhone has been submerged in a liquid, there may be some corrosion or debris on the logic board connections that cause this error message. Remove the logic board and clean all of the contacts with a soft cotton swab and high concentration isopropyl alcohol (at least 90%).

Weak or lost wireless connections ¶ 

You have trouble connecting to a wireless network.

Dirty antenna grounds ¶ 

If your iPhone has been disassembled before, it's possible that finger oils were left on the grounding locations for the Wi-Fi or Bluetooth antennas. These oils will cause grounding issues for the antennas, which could lead to a weak signal or no connectivity at all. Be sure to clean all grounding points with an electronics cleaning solution before reassembling your iPhone to prevent grounding issues.

No audio or distorted audio through speakers or headphones ¶ 

Your iPhone 4S turns on and appears to work, but when you plug in headphones or speakers, the audio doesn't play properly.

Bad headphones/speakers ¶ 

It's unlikely your headphones or speakers are bad, but it's worthwhile to eliminate these as the source of your problem at the beginning. Try your iPhone with another set of headphones or speakers just to make sure that the problem is with the iPhone.

Bad audio jack ¶ 

The most likely cause of audio output problems on iPhone 4S is a bad audio-out jack. If you have determined that the problem does not lie in your external speakers, you should replace the headphone jack.

Restore iPhone 4S ¶ 

Your iPhone is behaving erratically or displays the text "Use iTunes to restore" on startup

Corrupted software ¶ 

It isn't often that Apple gives specific directions about how to fix your problem! Restoring the iPhone 4S will erase everything on it, so make sure everything on the iPhone 4S is stored elsewhere prior to restoring. To restore, connect your iPhone 4S to a computer with iTunes installed. Click "Restore" on the iPhone 4S summary page (click on your iPhone icon on the left menu to find this page). Follow the directions to restore. If your iPhone 4S displays the text "Please wait. Very Low Battery," leave it plugged in. This charges the iPhone 4S enough to be able to restore. If the iPhone 4S hangs on this screen for long periods of time, you may need a new battery.

Force restore mode ¶ 

If your iPhone 4S is hanging with an Apple logo, or exhibiting some other software problem that prevents iTunes from recognizing it, you can force it into recovery/restore mode and then use iTunes to restore the software.

If the device is powered off, plug one end of your USB cable into the iPhone 4S and leave the other end disconnected. Press down on the Home button, and keep holding it down while you plug the USB cable into your computer. After 5-10 seconds, you should see a "Please Connect to iTunes" image on the iPhone 4S, and iTunes should prompt you to restore the software; follow the prompts and the instructions given above.

If the device is powered on, hold down both the power and home buttons until the device reboots and displays the "Connect to iTunes" image (generally, 5-15 seconds).

New Edit ¶ 

No Power ¶ 

If your iPhone 4 or 4S has no power, or power issues, start with some quick checks.

For symptoms like:

• Will not power on

• Black screen

• Shuts off after removing power

you want to first try to:

a. Restart the iPhone.

b. Reset the iPhone.

Should this not resolve the no power symptom than a more systematic approach must be taken.

1. Check on/off button.

Check that the on/off button is not stuck (up or down.)

Is the button functional?

Yes Go to step 2.

No Determine if the issue is caused by accidental damage (drop or liquid damage).

2. Charge battery.

Plug the iPhone into a known good power adapter and cable to charge the battery for up to 2 minutes.

Is any image displayed on screen within 2 minutes?

Yes Go to step 4.

No Go to step 3.

3. Reset the iPhone.

Attempt to reset the iPhone while connected to known-good power.

After attempted reset, is any image displayed on screen?

Yes Go to step 4.

No Determine if the issue is caused accidental damage (drop or liquid damage).

4. Verify iPhone status.

Identify if iPhone woke up to the “battery trap” or to an iOS screen, such as:

- “slide to unlock”

- Apple Logo (startup)

- “connect to iTunes” (at left)

Did the iPhone wake to the battery trap image or an iOS screen?

Battery Trap

Block Image

Go to step 5.

iOS Screen Go to step 6.

5. Continue charging.

Charge the iPhone for up to an additional 10 minutes.

Did the iPhone wake to an iOS screen?

Yes Go to step 6.

No Determine if the issue is caused by accidental damage (drop or liquid damage).

6. Identify iOS screen.

Identify if the iPhone woke to “slide to unlock” rather than the Apple logo or “connect to iTunes.”

Did the iPhone wake to “slide to unlock?”

Yes Go to step 8.

No Go to step 7.

7. Restore with iTunes.

Restore the iPhone using the latest version of iTunes. If restore fails, attempt DFU restore.

Warning: This will delete all data on the iPhone.

Was restore successful?

Yes Go to step 8.

No Determine if the issue is caused by accidental damage (drop or liquid damage).

8. Test battery.

Allow iPhone to charge for 2 more minutes, then unplug the iPhone.

Did the iPhone immediately power off?

Yes Determine if the issue is caused by accidental damage (drop or liquid damage).Replace the iPhone’s battery.

No Go to step 9.

9. Time for a dismantle and further investigation of the logic board.

hi i have tuned on a speech mode on my phone and i have to double tap all keys and it will not let my screw down the page to tune it off help please

scott, · Reply

Mine has started doing the same thing today! Voice keeps saying "double tap" and I have to tap several times to get it to work. It is driving me crazy!


Scott, I am having the same problem, please let me know if you find a solution at patrickf27@comcast.net. Thanks


Use siri and tell her accessibility. Then when she gets you there, turn off the voice over


use siri to get to "accessibility" and turn off voice over


I had that same problem as well however if you tap the home button 3 times in a row it'll deactivate it. It's rather frustrating to have this on and hope this helps. Plus it's a quick step and you don't have to get your phone to any particular screen.


I have the same problem. I have to double or tripple tap my phone to get anywhere on it and then I can't scroll down to change anything. I have tried to reboot my phone to see if that changes but it doesn't. I tried everything but can't do a thing with my phone. Tried the accessability but that doesnt even work, it keeps trying to call people instead. Tried to do an update and it says there is an unknown error but I cant even figure out what that error is because it doesn't say. Any other suggestions?


I have a iphone 4 and it won't change from portrait to landscape. Do you know anything to try?

My daughter dropped her phone in water I have taken the guts out and cleaned with isopropyl alcohol . When turning on the apple logo appears for a nano second and then black screen. Siri still talks and on occasion the plug or plugged in symbol will appear again only for a nano second. I have tried a forced reeboot and again apple logo for a second then gone.if pluged into a computer I tunes does not recognise it and recomends a restore however this would remove her many photos etc so this would be a last resort. I would appreciate any help or advise . Thankyou :0)

Hi I have a iPhone 4 and brought it second had it keeps malfunctioning and going white screen till it goes flat.

I took it to a phone shop they said it was the screen so they replaced it with a new one then as soon as I left the shop it did the same thing again.

I took it back a second time and they replaced the screen with a second hand one at no charge but charged me for a new battery and sure enough I left the store and white screen again grr I don't want to take it back again to incur yet another charge do you think it is the logic board ??? Pretty funny the phone stores motto is no fix no charge lol

My spouse has an I phone and it has a problem anytime she turns it on it talks continuously, stating what page he is on what app she opens etc, until he turns it off. We have no idea where the setting is that made it do that but it sure is annoying.

After having downloaded the last Software update 8.1.3 my IPhone 4S now has a short battery life and the phone becomes very hot. I have never had any problems with my phone and now I have to charge it at least twice a day to use it!! I have changed the battery thinking that it might have been a battery problem, but it hasn't helped. Any suggestions - maybe apple can put through another Software update and fix it.

I can't figure out why some of my "photos" aren't actually visible on my phone however they show up as "local disc" icons when I look at my iphone albums on my cumputer and are all 693 bytes. There are a couple hundred of them and when I try to delete them I get a message saying "delete failed. The device has either stopped responding or has been disconnected." Does anyone know how I can fix this please?

Tracy, · Reply

You Need to run a Malware/Anti-Virus on your phone a.s.a.p.... My phone was doing the same thing and the 360 Security software caught it and fixed it.. It runs like new.
