Hi! My Galaxy Note 9 has recently started having a really strange issue.

When I press the power button and unlock it using my fingerprint, I can clearly hear the phone unlocking, but my screen stays perfectly black. When I press the power button again, it makes the stock "locking" noise that it makes. The little click.
If I don't relock the phone, it still can be used! I can actually click icons, accidentally send texts, etc. but no image....

Here's where it gets weird.

If I tap the screen two to four times and THEN press the power button, my screen turns on! I'm then able to use the phone like normal. Crazy!

However, for whatever reason I cannot use this trick when I get a phone call. So I just have to call people back.

Has anyone experienced this before? Do you have any tips to fix the problem? I have already tried restarting the phone, and powering it off and turning it back on. My last resort is a factory reset.

Welcome to XDA🤗

May be a rootkit. If your running anything lower than Android 9, a factory reset may not purge it ie X-helper. The longer you wait the more damage malware can potentially do.
Delete Google account from phone and...
Nuke it, then reset your Google account password after factory reset.
If it persists, reflash rom. If it still persists it's hardware.

Two days ago I did click a link in a spam ad. And then yesterday the problem kicked in, so your suggestion has some pretty strong credibility in my mind. I'll take the actions you recommend. Thank you!

Maybe go with Brave browser in the future and add this modification to the new load. It globally blocks ads and some of the worst sites as well.
