LG’s latest G4 flagship smartphone is a real joy to use and this should also include its display. Just as its predecessor, the new version comes with a 5.5-inch LCD display. The quad-HD touchscreen is incredibly sharp and has a 2,560×1,440-pixel resolution with a 534 pixels per inch (ppi), which should make it an ideal choice.

As if this is not enough, LG is here to claim that the G4 screen – an IPS Quantum Display is the first of its kind, being no less than 25 percent brighter (500 nits) and also having a 20 percent wider color range than all the previous QHD screens on mobile devices. Despite of all these, the LG G4 touchscreen has been noted as affected by an issue which makes it unresponsive.

If you believe that I am talking about an isolated case, you should think twice as long as there is an entire thread at XDA dedicated to the very same issue. LG’s G4 touchscreen is lagging and is not registering quick taps and swipes as it should, which makes a real problem for its users all around the world.

This prevents the handset from utilizing the Knock On and Knock Code features. To be more precise, with Knock On, you have to tap the screen twice in order to wake up the phone; and if you choose to tap twice once more, the smartphone goes back to sleep. With Knock Code, it is up to you to create a line of two to eight taps that lock and unlock the device, but what good is it if you cannot use properly?

liamR, known as a senior member on XDA Developer forum, has even started a poll to collect more about the touchscreen issues G4 users are facing and the versions which seem to be the most affected. According to these reports, I have reasons to believe the fact that LG G4 smartphones from Verizon and T-Mobile are the most affected, so what is the company doing about that?

Well, LG is definitely aware about the touchscreen issue reported by some users, but it is not yet able to identify the cause of this problem. Some of us have been using the LG G4 smartphone and have found no problems so far, but if you want to be sure about that, you can check your touchscreen performance with the help of these steps:

How to Check your LG G4 Touchscreen Performance:

  1. For the start, you have to open the Dialer;
  2. Then, enter 277634#*# in order to go to the Service Menu;
  3. Go to Device Test -> Service Menu – Manual Test -> Touch Draw Test – Manual;
  4. It’s time to touch/tap/knock/slide on the test area until it is almost full and watch for missing registration (you will touch the screen and you will see no red mark);
  5. Do not hesitate to repeat the same procedure several times.

Whether or not this guide showed you that you have problems, do not hesitate to leave a comment at the bottom of this article to let me know.

As for LG’s job, we can only pray that the issue is nothing more than a software problem that can be fixed with a simple update.
