iPhone and its accessories are very reliable. One of those accessories is the mobile device's screen. Apple iPhones are the pioneering gadgets for the use of glass screens. And they do not use any kind of glass screen; they replace the traditional plastic screen with Gorilla Glass. In that case, very little fear gets to an iPhone user when their device is struck by a rigid object or drops, even on a hard surface. However, some users are complaining about the left side of iPhone not working.

Users who complain about the left side of the iPhone not working cannot swipe right, especially when they want to go back. They cannot type the letters of the keyboard that are on that side of the screen like Q, W, Z, A, etc. And certainly, other buttons/links that fall on the left side cannot be used. This situation can be somewhat uneasy for any user.

Well, don't worry. Some of the causes and solutions for the left side of the iPhone screen not working are addressed in this article.

Why Does the Left Side of Your iPhone Not Work?

For any part of your screen to work when you touch it, there are physical parts that send instructions, and software acts on the directives. One of the reasons the iPhone's left side of the screen is not working is the hardware (digitizer, logic board, or LCD screen) may be faulty. And when the hardware is not defective, the device's iOS system may be completely broken. Another cause for the lack of response may be the wrong screen protector installation and its exposure to dirt or liquid.

What Do You Do If Half of Your Screen Won't Work?

We have firstly identified that both software and hardware components may be responsible for the left side of the iPhone not working. To correct any of these problems, below are the solutions.

1Remove iPhone Protector and Case

If you have gotten a screen protector for your iPhone, you can remove it. Users are often asked to remove the protector because they may have wrongly installed it for them. If yours was improperly installed, the responsive parts of the screen's hardware might not be sensitive to your touches. A similar fix is also to remove the case of your iPhone. Using a conductive (plastic) case can cause phantom presses on your iPhone. Phantom presses or ghost touch is when nonexistent touches make your device perform certain functions by itself.
