The diagnostics menu is available on Samsung Galaxy smartphones that feature the company’s One UI, although some users may not be able to access it due to operator-specific locks. Also, Technastic reports that the same code (or a slight variation of it) may work on certain older Galaxy phones with TouchWiz. We tested the process with an unlocked Galaxy Note 10+ and the diagnostics menu came up with no issues. Your mileage may vary, but it’s worth a try if you think the phone may be malfunctioning.

The diagnostics menu is accessed by entering a specific code through the phone app. This process is performed just like you would dial a phone number, although you don’t need to click the call button as the diagnostics menu will automatically appear when the last symbol in the code is entered. To access the secret menu, follow these steps with a newer Samsung Galaxy smartphone:

1. Turn on your phone and log in with a password, PIN, or fingerprint, if necessary.

2. Tap the “Phone” icon to open the app.

3. Tap the Keyboard tab to bring up the dialer.

4. Enter the following code: *#0*#

After entering this code, the diagnosis menu appears automatically. You’ll see a light gray screen with square white buttons, each assigned tests for specific components. Tapping a button brings up its associated test, which you can use to assess your phone’s hardware and determine if a component is no longer working properly.

The reasons behind ghost touch on Samsung devices.

We are about to show you how to fix Ghost Touch on Samsung devices. But do you know what caused it? The most common cause of Samsung Ghost Touch is a software issue. If you’re having problems, it’s most likely a hardware issue, e.g. B. a broken screen.

1. Bad charger or bad charging cable

This is the most common cause of ghost touch on Samsung smartphones. If your phone starts tapping itself when you plug it into your charger, the charger may be the problem. It is possible that the charger is not compatible with your smartphone or is poorly designed.

2. Software update problems

However, a software problem is rarely the cause of this problem. Still, buggy software code can cause your screen to freeze or respond to random touches.

3. Overheating or extremely cold weather

The phone needs to be in a temperate environment for the screen to work properly. If the device is frozen or overeating, you may feel a spirit touch. Though ghost touch response isn’t strong, it does affect some parts of the screen.

4. Bad screen protection

If you have a bad screen protector on your Android phone, you can experience ghost touch – especially if it’s not securely attached to the screen or if there are particles between the screen and the protector.

Firstly, if you only get a ghost touch while charging your phone, your best bet is to get another charger that is compatible with your phone. We recommend using the charger that came with your phone if you still have it. Otherwise, just get a new charger from a reputable company or your brand’s official store.

2. Keep the screen clean

To perform an activity, the screen relies on contact between your finger and the touchpad. This also applies if the screen contains foreign particles such as dirt or dust from the environment. In this situation, keep your phone screen clean to avoid Android ghost touching issue.

It’s simple: turn off the device, get some clean tissues and gently wipe the screen. The screen must not be scratched with sharp objects.

If your screen is cracked or scratched, ghost touch may also happen. So make sure the phone is scratch free.

3. Take breaks from using the screen

Keep the phone at a normal temperature and remember to take breaks between screen uses especially when the phone is hot to fix/avoid ghost touching on your Android phone. Also, avoid using the phone in extremely hot conditions, such as B. direct sunlight to use.
