SAMSUNG A71 GHOST TOUCH ISSUE

[캍]

There are times that my phone just freezes out of nowhere and i just lock and unlocked my phone again  then it's working normally again 

Sometime my phone begins touching my itself and i just lock and unlock my phone again then its working normally again

I don't want to do this everytime it happens. Is there anything that can solve this problem without factory reseting the phone? 

Thank you so much.

You may try the following:
- Wipe cache partition
- Dial *#2663# (to update SP FW)
- Check for software updates
- Toggle "Touch Sensitivity" on and/or off

If you have a newly-placed tempered glass on your screen or if you had a software update recently installed, these could be factors too.

To gauge whether the issue is hardware or software-related, try to enter Safe Mode (if a factory reset is not possible). If the ghost touches still persist even in Safe Mode, it's possible that the issue is already at hardware level.

You may also do some screen touch tests/diagnostics to check if a part of your screen is no longer working/responding to touches (especially around the area where the ghost touch happens). If this is the case, then the issue may be caused by hardware malfunctions. One way to find the exact area where the ghost touch occurs (if not yet determined as of now) is to do a screen recording and turning on "Show taps and touches."

You may also consider visiting an authorized Samsung service center to be sure. If the problem has been found to be at hardware level, then replacing the actual screen is needed.

If the issue is at the hardware level. What can I do?

Once it has been determined at the service center that it is at hardware level, screen replacement can solve the issue.

Hello 캍,

We are sorry to hear about your experience with your Samsung Galaxy A71 having ghost touch issue. I feel and understand why you are worried for a device that you've take care so much. If my device is facing similar experience, I will be bothered too.

Before you try out the below recommendations as to your solution, be sure to check if your device's software are updated with the latest version. Please check how to update your mobile device's software in the following order. 

Step 1. Go to Settings > Software update.

Step 2. Tap on Download and install. 

Step 3. Follow the on-screen instructions.

Check 1. Attachments to the screen may affect the touch sensitivity.

If you attach accessories, such as screen protectors to the touch screen, the touch screen may not work properly. Small stickers, such as protective labels, can also affect touch sensitivity. In particular, some Samsung-unapproved protective glasses or films have only adhesive on the side edges, and if these products are attached to the screen, the protective glass or film may not adhere completely to the screen.

Because of this, some areas of the touch screen may not recognize the touch and may respond intermittently. After removing the attachment, check the touch function again. If the attachment is removed and the touch works properly, your phone has no problem regarding the touch screen.

Note: It is recommended to use Samsung-approved accessories. Using unapproved accessories may cause performance problems.

Check 2. Be careful when touching the screen.

If you are wearing gloves or your hands are not clean while touching the touchscreen, or if you tap the screen with sharp objects or your fingertips, the touchscreen may malfunction.

Check 3. Moisture may affect the touch screen.

The touchscreen may malfunction in humid conditions or when exposed to water.

Check 4. Activate the touch sensitivity feature.

Your Galaxy phone has a feature that increases the touch sensitivity of the screen for use when a screen protector is attached. If you feel that the touch on the screen has become relatively less sensitive after using the screen protector, follow the steps below to enable the Touch Sensitivity feature.

Step 1. Go to the Settings, and then select the Display menu.

Step 2. Find and tap the switch to activate the Touch sensitivity.

Note : 

• If there is no response on the screen, or if the screen is cracked, the device may need repair.
• Device screenshots and menus may vary depending on the device model and software version.

If that doesn't fix the problem, you may submit an error report through the Samsung Members app as follows:

Step 1. Long press Samsung Members icon on Apps screen and tap Error reports.

Step 2. Tap OK on agreement popup to send system log data.

Step 3. Select Symptom category "Sensor/Touch".

Step 4. Describe the problem in details and SEND.
