iPhone X screen burn-in problem
One of the main attractions of the new iPhone is its 5.8-inch OLED panel. If there are long-displayed or very often displayed elements on the screen, it can cause that they are noticeable on the panel even when they are not supposed to be. This is one of the drawbacks of OLED screens. This is not just about the iPhone X but also Pixel 2 XL has the same troubles.
How to avoid iPhone X screen burn-in
Apple knows about the potential risk and therefore released a short manual for iPhone X owners to maximize the service life of the Super Retina OLED panel.
An important point is to update the iPhone to the latest version of iOS as soon as you have it available. Apple also recommends not to overheat the brightness of the panel, ideally set its automatic control (Settings – General – Accessibility – Customizing the Display).
Another point is to activate the phone's auto-lock, which turns off the display. The appropriate settings are found in the Settings> Display and Brightness menu> Automatic Lock. Apple recommends setting the shutdown interval to 30 or 60 seconds. This prevents the phone from lying idle on the desk with the display activated.
Mysterious vertical green lines on iPhone X
Another reported problem is the vertical green lines that appear along the edges of the panel. There is unknown cause of this phenomenon, restarting or restoring factory data will not remove it. According to MacRumors, Apple is swapping the affected iPhones for new ones. The defective pieces are further subjected to an analysis that could reveal the cause of the defect.
Display of the iPhone X is unresponsive in cold temperatures
The display of the latest iPhone X may stop responding at low temperatures. This is probably a software issue because the lock and unlocking of the device eliminate the problem.
How to fix the iPhone X problem with an unresponsive display in low-temperature:
Apple announced that they know about the issue and it will be fixed in next system update (version 11.1.2). The iOS 11.1.2 update can be downloaded for free on all eligible devices over-the-air in the Settings app. To access the update, go to Settings> General> Software Update.
Apple also released the manual that out of the temperature range of 0 to 35 degrees Celsius, called the comfort zone, the iOS device may exhibit certain interactions that adapt to temperature changes.
Crackling or buzzing 'sounds from the earpiece speaker of iPhone X
Another repeatedly reported device failure is the crackling or buzzing sounds when the speaker is loud. While some users have noticed noisy sounds at peak volume, others notice them at 70 percent level, which is quite unpleasant. Unfortunately, the problem's not just present for media playback, as it also affects call quality
Good news is, that Apple changes devices with a defective speaker automatically to new ones.
Just as with previous problems, users are asking for a device without their hidden defects, and the widespread problems show that the iPhone X is not a completely trouble-free device. However, it has to be said that several million units have been sold in a short time, so there is nothing extraordinary about the occasional occurrence of anomalies.
