Like most phone errors, the Galaxy A70/A71 touchscreen problem is fixable through a simple restart process. Unfortunately, it’s tricky when you can’t reboot from its power menu due to the touchscreen issue.

Use a secret button combination to initiate a force-restart sequence to do a reboot. Doing so will allow it to refresh its system memory, which should help address minor bugs and glitches that cause touchscreen problems.

This button combination is handy when troubleshooting since it lets you operate your Samsung Galaxy A70/A71 without touchscreen controls. This way, you can reboot your Samsung phone as often as necessary to fix its system-related problems.

Remember, you can also use the force-restart if the touchscreen problem is due to software bugs and glitches. Refreshing your Samsung phone’s system memory via a reboot won’t help with physical defects and hardware damage.

Step 1: Hold your Samsung Galaxy A70/A71’s volume
down and power keys simultaneously.

Step 2: Release both keys when a Samsung logo appears
on the Galaxy A70/A71 screen.

Step 3: Wait while the Samsung Galaxy A70/A71
completes the bootup sequence.

Step 4: Swipe your Samsung Galaxy A70/A71’s touchscreen to test if it works.

Dirt and moisture can affect the sensitivity of your Samsung Galaxy A70/A71 phone. Thus, you must always keep your Samsung phone dry and clean to prevent touchscreen problems during use.

If its touchscreen has a layer of dirt, you must wipe it with a lint-free microfiber cloth to avoid accidentally scratching its surface. You must remove the moisture from your Samsung phone’s touchscreen, as it can make it unresponsive to your input.

You can apply distilled water or alcohol on the microfiber cloth to better clean your Galaxy A70/A71’s touchscreen as you wipe. Samsung recommends these liquids since they’re not harmful to electronic devices.

Clean the touchscreen 

However, it’s important to note that you must exercise caution when cleaning your Samsung phone with any liquid since it can still cause internal damage. Also, you must never use alcohol with less than 70% concentration since it contains too much water.

These are essential considerations because you don’t want to cause further damage while fixing the Samsung Galaxy A70/A71 touchscreen issue. 

FIX 3. Remove the Galaxy A70/A71 screen protector

Depending on the screen protector your Samsung Galaxy A70/A71 has on, it may affect its touch sensitivity. When this happens, you may encounter hiccups when operating your Samsung phone, where the device is unresponsive to some of your touch inputs.

In such cases, removing the troublesome screen protector should help fix the issue with your Galaxy A70/A71 touchscreen acting up. It’s a necessary compromise when your Samsung phone only has a cheaper, low-quality screen protector.

However, we only recommend doing this temporarily due to the importance of screen protectors. We suggest buying a decent screen protector as soon as possible to protect your Samsung phone from scratches without affecting its touch functionality.

If you’re uncomfortable removing your Samsung phone’s screen protector, increase its touch sensitivity. This way, your Galaxy A70/A71 won’t have issues registering your touch inputs even if it has a cheaper, low-quality screen protector.

This compromise is the ideal way to deal with the problem of a Galaxy A70/A71 touchscreen issue while you look for a compatible screen protector. After all, you don’t want to sacrifice your phone protection unless necessary.

Unfortunately, you can only rely on this method if your Samsung phone’s touchscreen isn’t wholly unresponsive to touch inputs. Otherwise, you can’t navigate its settings menu to toggle its touch sensitivity feature.

Furthermore, increasing the touch sensitivity is only remarkable if your Galaxy A70/A71 always had a screen protector since day one. If you never put a screen protector on it, toggling this feature now won’t make any difference.

Step 1: Go to Settings.


Note: Pulling the notification bar of your Galaxy A70/A71 and
pressing the gear icon in the quick settings panel will
also open the device’s settings menu.
Step 2: Go to Display.

Step 3: Scroll down and enable its Touch Sensitivity switch.

Step 2: Scroll down and select its Software Update menu.

Step 3: Click “Download and Install.”

Step 4: Go to Download.

Note: If the “Auto-download over WiFi” feature is active,
skip this step since your Galaxy A70/A71 has likely completed
downloading the update in the background.

Galaxy A70/A71’s system software.

Step 6: Wait as your Samsung Galaxy A70/A71

to test if the issue persists in safe mode.
Step 5: Hold your Samsung Galaxy A70/A71’s power and volume down
