18 of the most annoying Galaxy Note 4 problems and how to fix them

Samsung Galaxy Note 4

You probably spend more time with your smartphone than anyone else, so what do you do when your significant other is being difficult? Don’t tear your hair out in frustration, if you’ve run into some Galaxy Note 4 problems, don’t worry — it will be okay. Now, take a deep breath and see if you can find a fix to smooth things over right here.

Problem: Gap between screen and bodyGalaxy Note 4 Screen Gap

A bunch of reports sprang up shortly after the Note 4 release in South Korea complaining about a gap all around the screen. There are photos and videos of people sticking business cards into the gap between screen and body, both at the top and sides of the Note 4. But “Gapgate” may have been intentional.

As the user manual states, “a small gap appears around the outside of the device. This gap is a necessary manufacturing feature and some minor rocking or vibration of parts may occur. Over time, friction between parts may cause this gap to expand slightly.”

Samsung stressed that it’s normal. “The reported issue does not impact the functionality or quality of the Galaxy Note 4,” a spokesperson told TrustedReviews. “We assure our customers that all Galaxy Note 4 units meet our strict manufacturing and quality control standards.”


There’s a good chance that you wouldn’t notice the gap unless it was pointed out. Since the issue was publicized, a lot of people have shown off similar gaps on the other smartphones, and some Note 4s may be worse than others. All you can really do is ignore the gap, or return your Note 4 if it’s under warranty.

Glitch: ‘OK Google’ doesn’t work

A few people have been reporting issues getting the voice command “OK Google” to work correctly every time. For some people, it worked fine when initially set up, but then stopped working after a couple of days. Others report that the “Always on” function that allows you to use the command when the screen is off doesn’t work properly.


  • The “OK Google” voice command and “Always on” setting shouldn’t be incompatible, but some people have had success turning off Voice wake-up in the Settings menu of S Voice. Others report the opposite  — that S Voice must be on for “OK Google” to work.

Potential solutions:

  1. Make sure that Settings > Language and input > Voice search > “Ok Google” Detection is set to Always on. Try restarting your Note 4.
  2. If you’re still having the problem, there’s a good chance that a specific app is causing it. You could check your apps one-by-one —  start with wearable apps and anything that accesses the notifications. Alternately, you can factory reset your phone and selectively re-install apps until you find the culprit.

Problem: Galaxy Note 4 randomly restarts

A few people have encountered a random reboot issue with their Note 4 handset. The phone will simply restart itself at random intervals with no obvious cause.

Potential solutions:

  • If you’re using a Micro SD card in your Note 4, remove the card from your phone and test to see if the random reboots still occur. If the reboots stop, back up the data from the card on your computer, re-insert the card in your Note 4, and try reformatting it on via Settings > Storage > Format SD card.
  • You can try a factory reset. Make sure you have all your data backed up, and then go to Settings > Backup and reset > Factory data reset > Reset device > Erase everything.
  • If the issue persists, contact your retailer, carrier, or Samsung and arrange a return and replacement.

If you’re upgrading from another Samsung device to the Note 4, you might be annoyed by the lack of a Menu key. The key to the left of the Home button is now Recent apps, in line with the rest of the Android world.

Potential solutions:

  • Most developers have updated their apps to include a menu option as a software button. It’s usually an icon of three dots — you may have to swipe to reveal it.
  • For older apps that haven’t been updated with a software option, you can long-press on the Recent apps key to expose the menu.

Issue: Dead pixels

If you notice that your new Galaxy Note 4 has dead pixels on the screen, not to worry — you have a few options.

Potential solutions:

  • Try using an app like Dead Pixel Detect and Fix to see if you can get them working again.
  • If that doesn’t help, your best bet is to request a replacement from your carrier, or contacting Samsung about a repair.
