The touch screen of the Samsung S7500 phone does not reflect

We recommend that you do the following:

First, try to change a SIM card to see if it is caused by incompatible SIM cards. If this phenomenon still occurs on the mobile phone after changing the SIM card, it may be caused by the incompatibility of the third-party software, it is recommended to turn the mobile phone off and reboot, when the logo appears, press and hold the menu key (the small square touch button in the lower left corner of the screen), until the safe mode appears, delete the third-party incompatible software, and then restart the mobile phone after deletion. If this is still happening after doing this, it is recommended to take your phone to a Samsung local service center for further inspection by an engineer.

It should be that the touch screen is broken, and it is recommended to repair it.

In your case, the system software is not installed, please find a new flashing package to re-flash. Some flashing packages also have to add the capacitive screen touch screen optimization package again, please pay attention to the corresponding flashing prompt of your ** flashing package.

If your phone is experiencing a situation where the touch screen is not sensitive and malfunctioning, it is recommended:

1.Check if the phone has a film, if there is a suggestion to cancel the screen film and try it.

2.If the touch screen of the mobile phone is completely malfunctioning, it is recommended that you restart the machine and observe it again.

3.Try to update the system version of your phone (Note: Please back up the data in your device before upgrading).

4.If it doesn't work, back up the data in your device (contacts, text messages, **, etc.) and try to restore factory settings.

If the problem persists after the above operations, it is recommended that you bring the machine, purchase invoice, and repair card to the local Samsung after-sales service center for testing.

Customer service is pure nonsense, it's not good, how about the task manager, the software can also ask this, the hardware can only be repaired, reboot to try, and if it doesn't work, take it to repair.
