Can't swipe to answer incoming calls? Is this the reason
The main reason for this situation is static electricity. In fact, everyone should have this feeling. The drier the season, the more likely this problem will occur. Generally, this problem will occur when the mobile phone is placed in the pocket and a call is made. This is because the friction between the mobile phone and the pants in the pocket generates static electricity. As a result, the screen temporarily malfunctions. As long as the static electricity is eliminated, it can return to normal.
As for why this problem usually only occurs when a call comes in, it is usually no problem to take out the phone normally. This is because the screen will automatically light up when a call comes in, and we do not need to press the buttons, but we usually do it by ourselves. When you take out the phone, you need to press the physical button first to unlock it. When we press the button, a circuit is formed to eliminate static electricity, so there will be no malfunction. In addition, radio waves or magnetic fields can also cause static electricity. When a call is received, the signal received by the mobile phone changes, and static electricity may also be generated at this time, so sometimes this problem may occur when the mobile phone is placed in a bag.
The solution is actually quite simple. You can first try to wipe the screen 2-3 times in one direction with your entire palm to remove static electricity. If this method doesn't work, you can also try pressing the physical button first and then sliding to answer the question., but this method may not be successful. In comparison, the first method is more practical.
As for the inability to hang up the call, this situation is mostly due to software problems or signal problems. Sometimes there are bugs in the firmware or software conflicts that may cause this situation. This may also occur when the signal is not good. This kind of problem occurs not only on Apple phones, but also on some Android phones. You can try to update a system version. If it is still not solved and the problem is very serious, you can consider backing up the file and then restoring the factory settings or re-flashing the firmware.
The last question, I believe everyone should know that when the phone is locked, the incoming call will display the slide to answer, and when the phone is not locked, the incoming call will display the button to answer.
