8 common problems with the Samsung Galaxy Note 4 and how to fix them
The highly-anticipated follow up to the Galaxy Note 3 brought with it the latest and greatest processing package, a gorgeous QHD display, fast charging capabilities, and the myriad of software features that Samsung is known for. That said, the Samsung Galaxy Note 4 is not without its issues.

Disclaimer: Not every user of the Samsung Galaxy Note 4 will face these issues, and it is quite likely that you won’t come across any of the problems listed below.
Problem #1 – Gap between body and screen
“Gapgate” has been a trending topic since the Galaxy Note 4 released, with their being a small gap around the edge of the device. Though this shouldn’t affect the performance of the device, but users might experience minor vibration with parts.
- This is a design choice made by Samsung, and has been mentioned in the user manual since the Galaxy Note 2. The gap is barely noticeable, and the issue only becomes a big deal if the gap expands. Unfortunately, the only “solution” is to pick up a replacement in that case.

There is almost always complaints regarding Wi-Fi connection when a new smartphone is released. Users of the Galaxy Note 4 have reported trouble connecting, and staying connected to Wi-Fi.
- Turn the Galaxy Note 4 and the router off for at least ten seconds, then turn them back and retry the connection.
- Go to Settings – Power saving and ensure that this option is turned off.

- If you are using a microSD card, remove this from the Galaxy Note 4 and check to see whether reboots still happen. If they stop, backup the data on the card and reformat it through the device by going to Settings – Storage – Format SD card.
Problem #8 – “OK Google” function doesn’t work
Some Galaxy Note 4 users have reported problems with getting the “OK Google” function to work. Sometimes, this application works after initial setup, but stops working after a couple of days. In other cases, the “Always on” function does not work as it should.
