Make sure that your hands are clean and dry, then try these steps:
Or other method
1 Restart Android Device
Before rushing into any other troubleshooting procedure, restart your Android phone or tablet to fix software glitches that may prevent the screen from functioning. To restart android device with touch screen not working:
In many cases, the touch screen will respond normally after the device reboots.
2. Remove Memory Card & SIM Card
Sometimes, faulty memory card or SIM card should take the blame. Therefore,
Power off your device (keep holding power button if the screen is totally unresponsive);
Remove back cover of your Android device and take off memory & SIM card;
Reboot the device and see if the problem is gone.
3. Put Device in Safe Mode
Corrupted or troublesome third-party apps could also cause touch screen problem on Android phone or tablet. Under the safe mode, all third-party apps that you download will be disabled. So if the touch screen works well in safe mode, then you should uninstall some of the third-party apps, especially those that were installed recently before the touch screen problem starts.
If your touch screen just lags or respond incorrectly, you can also try to enter safe mode in this method:
4. Factory Reset Android Device in Recovery Mode
If the touch screen is completely unresponsive, factory resetting the device in Recovery Mode may help. However, this will delete all data in your Android device, including downloaded apps, photos, messages, contacts, etc. Therefore, use this as the last resort and if possible, have a backup to your Google account beforehand.
5. Calibrate Touch Screen on Android with Apps
There are apps in Google Play Store that can calibrate your phone/tablet touch screen and improve its accuracy and responsiveness. These apps are especially helpful if your touch screen respond too slow or inaccurately. Type "touch screen calibration" on the search bar in Play Store and you should get quite a few results. Read the reviews carefully before download.
First try starting the phone in safe mode and check if the touchscreen works, If it does then a downloaded app is the cause of the problem. The trick is to find out which one.
If it doesn’t work in safe mode either then there is a problem with the touchscreen either a loose connection to the systemboard or it is faulty and will have to be replaced.
Here’s a link to the ifixit Samsung Galaxy J7 Glass / Screen Replacement guide, which may be of some help.
Before you open the phone to check the touchscreen cable or to replace the screen, try connecting a USB mouse via an OTG cable -example only to navigate through the phone so that you can send the pictures by email to your computer.
Make sure that the phone’s battery is fully charged before you do this, as the power for the USB mouse is supplied by the phone’s battery and it will discharge quicker than usual
If you have a pattern lock on the screen, unfortunately this method won’t work.
I’ve read a few comments here and sugest to get screen repaired. If clearing the cache on your phone or factory resetting did not fix the issue then it is a hardware issue. I was in the same position where the top of my screen didn’t work and only got worse overtime. I ended up paying $100 for lcd and glass replacement for my s8+ and is working fine now.
