Before Christmas I created a Norton account and installed the antivirus on my PC.
I am satisfied with it for now.
Confident of Norton products, yesterday I downloaded and installed the app Norton Clean on smartphone Samsung Galaxy ZFOLD3 5G, SM-F926B/DS model.
I ran the software to remove unwanted files twice.
After that, as I wish to use the phone as a tablet (unfolding the two screens) the enlarged screen turned to be wholly black and unusable.
I think that probably the app removed files believed to be unwanted but WHICH ARE NOT AT ALL!!!
INDEED, THEY WERE PROBABLY USED TO RUN THE SMARTPHONE AS A TABLET.
I kindly ask the developers the procedure to undo the removal and restore the deleted files.
Hoping not to be forced to take the smartphone to service.
