Having only a screen to interact with your iPhone, it could be quite frustrating if the iPhone touch screen not working or not responding. When this happens, most users rush to the nearest Apple Store only to find that the problem was not as frightening as it looked like.
If your iPhone is acting up too and is no longer responding when you touch the screen, before contacting Apple's technical people, you can try a few fixes on your own.
The touch screens work on detection and respond according to the interference in the flow of current that occurs when you touch a certain area.
If your iPhone fails to respond to your touch, it means that there is no interference, and thus no activity took place. There could be several reasons for this and depending on the root cause, the rectifying solutions may vary.
The solutions explained in this section are general and do not require any technical knowledge. Before moving to the advanced troubleshooting methods explained in the next part, you must try these:
This is a basic solution. A cheap quality screen protector can become a strong insulator for touch detection, and your iPhone's screen may fail to recognize when or on which area it was touched. If your phone's screen has become unresponsive, responds late, or responds only when touched in certain areas, removing the screen guard may fix the problem.
Although highly unlikely, sometime, a faulty SIM card or conflict-prone peripherals may make your iPhone's touch screen non-responsive. In order to resolve the problem, you can try removing both of them, first, one at a time, and then both of them together if the issue is not fixed.
Yet another most common and obvious reason for your iPhone not responding could be that its battery is too low or drained out. Plugging your phone to a power outlet and leaving it alone for 20 to 30 minutes could charge it enough to fix the problem.
If your iPhone screen is dirty or is covered with dust particles, either or both of the two may block the direct contact of your finger's touch with it. If the screen is protected with a screen guard that has become dirty, replacing it with a new, clean one would be the safest solution. On the other hand, if your phone has no screen guard, to clean the surface you can:
Note: You should never use any cleaning solvents or chemicals, even in diluted form.
If Your iPhone's Screen Responds Late
If by any means your iPhone can detect your touches but responds late, you are still in luck, and the first thing you must try to fix the problem is to restart your phone. Depending on the model the process may vary. To restart:
Press and release the Volume Up button, quickly press and release the Volume Down button, press and hold down the Sleep/Wake button, and slide the slide to power off the bar when it appears.
Press and hold down the Sleep/Wake button, and slide the slide to power off the bar when it appears on the screen.
Your iPhone screen may also become less responsive if its 3D Touch is not configured properly or has some issues. That said, adjusting the 3D Touch Sensitivity manually is yet another way you can make your phone's screen respond to your touches normally.
To adjust 3D Touch Sensitivity in your iPhone, you can:
Over-populated device memory could be another major factor your iPhone may respond late to touches. Therefore, it becomes important to keep a close eye on its usage and clean up the storage on a regular basis.
You can follow the instructions below to check the available memory on your iPhone:
Note: An alternate method to check the device's memory is, connect your iPhone to a Windows or Mac computer, launch iTunes, click the Phone icon from the top, check the memory from the top section of the right pane of the Summary window.
If more than 80% of the memory is used, you should consider backing up some large files like videos, photographs, etc. and then removing them from your phone to free up some space.
If you have downloaded and installed an app recently and noticed that your iPhone started acting up after that, it's probably the program that is the main culprit and must be removed at the earliest. You can follow the easy steps described below to remove an unwanted/culprit app from your iPhone:
If the general solutions fail to help you fix the issue, you can try the following advanced solutions:
The first thing that you should and must do as soon as you detect that your iPhone is not behaving as expected is to power off and then power it back on. Restarting an iDevice has a proven record of rectifying most of the issues.
However, since your iPhone fails to detect your touch at all, and a normal restart requires you to slide the slide to power off on the screen, the only option you're left with is force restart.
Device Firmware Update or DFU is a state when your iDevice is active but is no longer able to accept inputs from you, and neither does it show anything on the screen, not even the Apple logo.
DFU Mode is almost similar to the Recovery Mode with the only difference where the latter shows the iTunes logo with a cable on your iDevice's screen.
If your iPhone fails to detect your touches, putting it in DFU Mode and then restoring its iOS may rectify the problem. However, because the process erases all your data from the phone and puts it to factory default, any information or files stored on your iDevice will be gone forever.
To perform a DFU Restore you must:
Put iPhone 8 or Above In DFU Mode
Note: If the Apple logo appears on the screen at any point during this process, this means your iPhone could NOT enter the DFU Mode, and you need to retry.
Put iPhone 7 Plus or iPhone 7 In DFU Mode
Note: If the Apple logo appears on the screen at any point during this process, this means your iPhone did NOT enter in DFU Mode, and you need to start all over again.
Put iPhone 6S Plus or Earlier In DFU Mode
Note: During this process, if the Apple logo appears on the screen at any point, this means your iPhone could NOT enter the DFU Mode, and you need to start all over again.
Note: If iTunes launched automatically, and an information box came up telling that you're in Recovery Mode after you put your phone in DFU Mode, you can safely ignore the message and click OK on the box.
Underneath the screen of your iPhone, there is a mesh of cables that are connected to a circuit plate, a.k.a. logic board or sometimes also referred to as motherboard. All the cords that are spread across the device meet at a ‘rendezvous' to form a joint and this joint are further connected to the logic board of your iPhone.
If your iPhone dropped on a hard surface such as a floor for a couple of times, the chances are that the connection between the cords and the logic board got to lose, which is further keeping your device's screen to respond to your touches normally.
The MacGyver Solution has helped many users resolve the non-responsive screen issue on their iPhone, and you can give it a try as well.
To do so:
WARNING: Make sure not to press the screen too hard as doing so may damage the circuit or the entire logic board altogether, and you may end up having a physically damaged iPhone.
Seen only in iPhone 6 Plus models, the term ‘Touch Disease' refers to the issue where the phones stopped responding to the touches after they fell on the floor for a couple of times, and the cables connecting to the logic board got to lose.
The only solution in this situation would be to take your phone to an authorized Apple store and let the professionals do their job.
Sometime, the updated version may make your iPhone act weirdly. If you have updated to a newer iOS, downgrading back to the earlier built could fix the issue. To downgrade:
Back-Up Your iPhone
Perform Custom Restore
Once done, you can restore your iPhone data back.
Instead of using iTunes, you can also consider trying a different, more efficient iDevices' troubleshooting tool called iSkysoft Toolbox, which not only rectifies most of the iOS-related problems, it even makes the entire process quite simple and straightforward.
To use iSkysoft Toolbox to fix unresponsive screen issue in your iPhone, you can:
iPhone's screen getting unresponsive is not an uncommon issue. However, if none of the above solutions is helpful, you should rather look for technical assistance from Apple itself.
