Part 1: Why Is My Android Experiencing Touch Screen Problems

Below are some of the most common reasons you’re experiencing touch problems on your Android smartphone.

• The touchscreen problemfreezes your phone, lags, or hangs.
• Some parts of the screen work fine, but some don’t.
• Your screen responds inaccurately (typing “a” gets you “q” or “z”).
• The touchscreen is automatically operating itself, resulting in ghost touch.
• It doesn’t respond to any taps, and the phone’s screen has stopped working.
• The device is physically damaged, or the screen is cracked or broken.
• Outdated devices are prone to the black/white/blue screen of death.

Part 2: Tips, Fixes, and Workarounds To Fix Your Oppo A78 Touch Problems

If any of the outlined reasons above are the cause of your touch screen malfunctioning, here are some solutions to fix it.

Method 1: Remove the Screen Protector and Phone Case

Some phone cases and screen protectors cause touch problems on your Android screen. This issue is prevalent if you recently changed your phone case or screen protector. It may be due to incompatibility, but you should remove them to see if your phone starts responding again.

Method 2: Clean Your Android Smartphone

A touchscreen malfunctioning can also be a sign of a dirty display. Since the screen relies on contact between your fingers and the touchpad to perform actions, this also applies to foreign particles such as dirt, debris, smudges, oil, and more. Clean your touchscreen with wipes or a soft cloth by gently wiping over the screen.

Method 3: Stop Using Your Android Device for a While

Touch problems also arise due to abnormal temperature changes. Your phone might experience ghost touch if it’s too cold or hot. For your screen to function correctly, it needs to be in a temperate environment. Remember to take breaks between phone usage, especially when the phone gets too hot. Avoid using your device under hot conditions, direct sunlight, or anything affecting your phone’s normal temperature.

Method 4: Restart Your Android

Performing a reboot sounds trivial with such a complicated issue. But sometimes, it’s often the most successful way to fix a touchscreen problem on an Android device. Restarting your Android shuts down and resets all background services, which may have led to your issue.

To restart your Android, press and hold the Power button for several seconds to switch off your phone. In other smartphones, you may need to hold down the Power button as well as the Volume Down button at the same time.

Method 5: Factory Data Reset Your Android

Before attempting to have your device checked for any hardware defects, you should try completing a Factory Reset. To do this, go to Settings > Backup and Reset. Next, tap on Factory data reset > Delete all.

Performing a Factory Data Reset will erase all your data and restore your device to its factory default settings. Creating a backup before doing this step is recommended, as you will lose all your personal data once the process starts.

Method 6: Put Your Android into Recovery Mode

If all else fails, placing your Android into Recovery Mode should be a last resort. Doing this method works similarly to the method above. You should perform this method if the screen is unresponsive and only the buttons on your Android are functional. Here’s how.

Note

Placing your Android into Recovery Mode is different depending on your Android smartphone. Refer to your owner’s manual to see which method is right for your Oppo A78.

Step 1A: Press and hold the Power button and Volume Down buttons at the same time. Continue holding both buttons until the screen starts.

Step 1B: If your Oppo A78 still has a Home button, press and hold the Home button and the Power button at the same time. Continue holding them until the screen starts.

Step 1C: If step 1A did not put your Android into Recovery Mode, press and hold the Power and Volume Up and Down buttons simultaneously. Continue pressing all three until the screen starts.

Step 2: Use the Volume buttons to navigate the choices, select Wipe data/factory reset, and confirm your choice with the Power button.

Step 3: Wait for the process to complete and for your Oppo A78 to restart automatically.

Method 7: Replace Your Android Touchscreen

If doing all the earlier workarounds and fixes couldn’t resolve the touchscreen problem, it could be the screen itself. While replacing the touchscreen yourself is possible if you have the technical know-how, it’s still best to bring it to a professional to prevent further damage. You should have your Oppo A78 checked by a technician if the screen is getting weak, has water damage, or has failing screen components.

“

Method 8: Bring it to an Authorized Service Center

Your phone touch problem might not be caused by the screen, even when you had it replaced. If your Android is still unresponsive, it’s best to bring your smartphone to an authorized service center or directly to the phone manufacturer, especially when all efforts are exhausted.
