How To Fix Part of the Touch Screen Not Working on OnePlus 12

You probably touch the screen of your phone hundreds of times per day. It’s no surprise that smartphone touchscreens are one of the most common components to fail, given their delicate glass construction. However, a part of the touch screen not working on your OnePlus 12 does not necessarily mean it is a hardware issue. There could be other reasons why your Android’s touch screen stopped responding.

If your phone’s touchscreen frequently fails to respond, there are several things you can try before calling a professional. This article will reveal those proven fixes you can easily perform independently.

Part 1. Why Is Part of My Screen Not Working

There are two possible causes as to why your phone’s touch screen is not working. One is the touch screen may have been damaged, and the other is the OnePlus 12 device may be experiencing technical difficulties.

If you drop your phone and it becomes stuck against something, the touch screen’s connectivity may fail. Only a part of the touch screen may sometimes become damaged and unresponsive. That may also occur when there is a technical failure, such as the phone hanging. A part of the touch screen not working can occur when malware is downloaded or when phone settings are changed.

Now, the problem can affect any Android phone, and users may encounter the following error messages on their respective phone models:

OnePlus 12 P40 lite half touch screen not working
Nexus touch screen not working
LG screen is unresponsive to touch
OnePlus 12 left side of the screen is not working

The touch screen incorrectly responds to your touch.
Half touch screen is not working.
The touch screen becomes frozen or hangs.
The screen flashes, flickers, or remains blank.

If you have already tried running the OnePlus 12 device in diagnostic mode and verified that it is not physically damaged, then the problem is most likely technical. If your OnePlus 12’s screen is not responding to touches for technical reasons, follow the methods below to resolve the issue.

Restart Your Device

When your touch screen stops working, the first thing you should do is restart your device. The operation is known as soft resetting. You cannot turn your device off from the option on the screen because the touch screen is not responding. Here are the steps to take.

Step 1: Hold the “Power” button until the OnePlus 12 device turns off.

Tip: If you hold down the power button for a few seconds, you will see the “Power Off” and “Restart” options on the screen. You can’t use it because the entire screen isn’t responding. Hence, you should press and hold the “Power” button for as long as necessary.

Step 2: When the OnePlus 12 device turns off, wait a few seconds.

Step 3: Press and hold the “Power” button to restart the OnePlus 12 device.

Turn On Safe Mode

You should switch to Safe mode whenever an application or piece of software causes a problem on your device. Only the most fundamental system components are loaded and used when operating in Safe mode.

Step 1: To force a restart, press and hold the OnePlus 12 device’s “Power” button for an extended period.

Step 2: Maintain pressure on the “Power” button. Take your finger off it once you see the manufacturer’s logo.

Turn Off Developer Options

Every smartphone is bound to have limitations. However, smartphone makers include a “Developer Options” menu for advanced users. Here, restrictions are removed, and user preferences can be customized.

If you enable Developer Options on some Android devices, they may stop working properly. If you have recently activated Developer Options and your touchscreen is no longer responding as expected, you should disable it. To do so, follow the instructions below:

Step 1: Launch the Settings app on your device.

Step 2: Select the System menu item, which usually locates at the bottom of the screen.

Step 3: Tap the Advanced options menu, then select Developer Options.

Step 4: You will then find the switch to turn it on or off. Disable itby toggling the button off.

Reset Device to Factory Settings

Resetting your device to its factory settings will return it to its state when you first unboxed it. All your phone’s data and installed apps will be erased, including any malware on your device that may be causing the issue to occur. Here’s how to restore your device to factory settings:

Step 1: Since your touch screen is not working, you can factory reset it using Google’s Find My Device web service.

Step 2: Go to Find My Device from any device and sign in to the Google account associated with the damaged screen device.

Step 3: After successfully logging in, you will see your device’s name. Select the Erase Device option.

How to Quickly Fix Bluetooth Not Working on OnePlus 12

Fortunately, despite there being many reasons why a problem could occur to your Bluetooth feature, there are also plenty of fixes.

2.2 Restart Android and turn on Bluetooth again

One of the most common solutions in technology is simply to turn it on and off again, which is the case to happen here. By restarting your device, you can clear out any problems you may be suffering from to help it get up and running again. Here’s how;

Turn your OnePlus 12 off by holding down the Power button
Wait for several minutes and then turn your phone on again
Wait for your phone to completely power up, so you’re on the Main Menu
Navigate Settings > Bluetooth and then enable the setting
Try to connect your Bluetooth device to what you were trying to do before

2.3 Clear the Bluetooth cache

Every service on your OnePlus 12 using a feature called a cache. This is where information is stored to help the feature run properly and give you the best experience. However, over time this can get messy and can cause problems with your Bluetooth feature.

By clearing the cache, you can restart the service and hopefully clear up any issues or problems you may be experiencing.

On your phone, navigate Settings > Application Manager, and you’ll see all the apps and services on your phone. Locate and select the Bluetooth service.
Select the Storage option
Tap the Clear Cache option
Go back of the Menu and restart your phone
Now turn your Bluetooth feature on and turn connecting it to your preferred device

2.4 Remove paired devices

Sometimes, you may have a problem with the OnePlus 12 device you’re trying to connect to via Bluetooth, especially if this is a device you’ve updated. To counter and repair this, you’re going to need to remove the paired devices saved with your device and then reconnect them.

Here’s how;

From the Main Menu of your OnePlus 12, head to Settings > Bluetooth > Connected Devices.
Turn Bluetooth on, and you’ll see all the connections your OnePlus 12 is paired with
Go through these settings and remove/delete/forget every connection on your device
Now when you go to connect to a device using Bluetooth, repair the OnePlus 12 device, enter the passcode, and use a fresh paired connection.

2.5 Use Bluetooth in safe mode

If you’re having problems with your connection and paired devices, sometimes you may have conflicting software faults in your device that are causing the problems. If this is the case, you’ll need to boot your OnePlus 12 in Safe Mode.

This is an operating state in which your phone will run the bare minimum services it needs to perform. If your Bluetooth works in Safe Mode, you know you have an app or a service that’s causing the problem.

Here’s how to find out;

Hold the power button down, so the Android power menu turns on
Long-press the power button again and the restart in Safe Mode option will come up
The phone will automatically boot into Safe Mode
Wait a minute on the Main Menu
Now turn on your Bluetooth and connect it to your preferred device

2.6 Turn on the discoverable feature

To ensure your Bluetooth can connect to other devices, it’s important to make sure you’re making your device discoverable to other Bluetooth devices. If it’s hidden, other devices won’t be able to find it, and sometimes it can bug and prevent connections.

Here’s how to turn on your Bluetooth discoverable feature;

From the home screen of your Android, navigate to the Menu> Settings > Bluetooth
Toggle the Bluetooth switch, so it’s on
Under the available settings, tick the box that allows your Bluetooth device to be discoverable
Turn your Bluetooth feature on and connect to the OnePlus 12 device you’re trying to connect too

2.7 Exclude Bluetooth issues of the other device

Sometimes, you might not even have a problem with your OnePlus 12, but rather the Bluetooth device you’re trying to connect to, whether that’s a Bluetooth speaker, an in-car entertainment system, or any other kind of Bluetooth device.

By testing out another Bluetooth device to see if it will work with your preferred device, you can rule this out from being the issue.

Disconnect your OnePlus 12 from the Bluetooth device and turn your Bluetooth off
Now take another Bluetooth device and connect this to the OnePlus 12 device you’re trying to connect too. This could be another Android device, or even a computer or iOS device
If the new device doesn’t connect to your Bluetooth device, you’ll know there’s a problem with your Bluetooth device, not your OnePlus 12
If the OnePlus 12 devices connect, you’ll know there’s a problem with your OnePlus 12

2.8 Place both devices within close proximity

One of the common misconceptions of Bluetooth is just how far the wireless range is of the service. You need to make sure your devices are well and truly close to each other to make sure a stable connection can be formed.

The further away the OnePlus 12 devices are from each other, the less likely the connection will remain secure. As a rule of thumb, Bluetooth can work up to 100 meters, but to play it safe, always try and keep your devices under 50m apart.

2.9 Avoid interference of other Bluetooth sources

The final consideration you’ll want to think about is that Bluetooth radio waves, or wireless waves, can interfere with each other. This means they can bounce off each other or get muddled up and make things confusing from your devices.

With this in mind, you’ll want to make sure you’re limiting the amount of Bluetooth activity in the area where you’re trying to use a device. While uncommon, this could be the problem.

To fix this issue, turn off all the Bluetooth connections in the area. This includes computers, laptops, mobile phones, tablets, and any other Bluetooth devices you may have. Then, try connecting your OnePlus 12 to the OnePlus 12 device you were trying to use. If it works, you know you were experiencing Bluetooth interference.
