iPhone Screen Flickering? Unplug It Before Anything Else
Apple puts disconnecting the charger among its first checks, and tells you to try a different outlet. The cause is often the power, not the phone.
iPhone Ghost Touch? Apple Names Six Separate Faults
Apple never says ghost touch. It lists six Multi-Touch faults, and three of them cover a screen acting on its own. Which one you have changes the fix.
iPhone Stuck on Call Ended? Sort It by What You See
Usually the proximity sensor has not released the display. Apple publishes a test you can run yourself, filed under display repair rather than calls.
iPhone Cellular Greyed Out? Start With Screen Time
A dimmed Settings row is a restriction rather than a fault. Apple documents the mechanism on two pages, and neither one is about cellular.

Apple documents four battery labels and gives Unknown more than one cause. A genuine battery that was never linked reads the same as a fake.
iPhone USB-C Port Not Working? Start With Your Model

iPhone Photos Not Showing? Get the Count First
Three taps give you a photo count, and that number decides everything. A normal count means hidden, not gone. Near zero is a different job entirely.
