LG G4 allegedly suffering by touchscreen issues

August 05, 2025

OurLG G4 reviewwas very positive, and most of our readers agree that thisis the best smartphone of 2015 so far. Needless to say we love the device here at Android Authority, but that doesn’t mean LG’s latest flagship smartphone is perfect. In fact, it seems the device may be plagued by touchscreen bugs.

A recent onslaught of LG G4 touchscreen issue reports inspired XDA Developers senior user liamR (who is also experiencing this problem) to create a forum post touching on the matter. The matter in question is that the phone seems to dismiss quicker taps and swipes, which is not standard when it comes to smartphone performance.

This is not only a problem during day-to-day usage, but it can murder one of the hottest features the LG G4 touts. This would be Knock On (and Knock Code). Definitely a cumbersome situation for LG G4 users, but not everyone seems to be affected by it.

The guys at XDA Developers also conducted a poll and so far 40.21% of the 194 participants have reported no issue at all. That also means nearly 60% of the voters did find a problem, though, and that is a significant number! By the way, 27.32% of voters reported having issues while using no screen protector, so we really can’t blame those.

Are you having problems?

Some of us at Android Authority have been using the LG G4 and have found no problems so far, but maybe you are. You can check your touchscreen performance by following these steps:

Please do let us know in the comments if you have encountered any issues. This seems to be more than just a slight manufacturing mistake, so we would love to hear more from users and get to the bottom of this.

Let’s just pray this is simply a software issue and LG can fix it soon. I have gone ahead and reached out to LG for a statement. Hopefully we can get a response soon. Until then, sound off in the comments and share your experiences!
