Samsung n7 19 smart phone, how to make the information screen white on a black background?

Through feedback, please try:

First, turn off the "negative color" function: turn on the phone settings-auxiliary functions-negative color-uncheck.

Second, check whether the third-party software similar to the theme of the mobile phone is installed or the screen brightness is adjusted, which leads to this phenomenon. I suggest you uninstall it and see if the phone is back to normal.

Third, back up the data of the mobile phone (phone book, SMS, multimedia materials, etc.). ), and try to restore the phone factory settings (Settings-Reset-Restore Factory Settings).

If the problem still exists, I suggest you take the three-guarantee certificate and send your mobile phone to the nearest Samsung service center for testing. Please visit:
