Why is the picture received by Samsung mobile phone WeChat a big whiteboard?

According to your description, I suggest you:

1. Turn the machine on again.

2. Go to phone settings-Application Manager-Download-Click on the problematic application-and try to clear the data.

3. Uninstall the client reinstallation attempt

4. Has the attempt to update the version of the mobile phone system improved?

5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (enter phone settings-reset-restore factory settings).

If the problem cannot be solved after returning to the factory, please send the mobile phone to the nearest Samsung service center for testing and further processing. Please click the following link to find out the specific location of Samsung Service Center:.

It is recommended that you apply for "booking to the store" in Samsung official website and enjoy priority maintenance service:/pre-order.

After the appointment is successful, please bring your machine, invoice and warranty card to the service center you reserved on time.
