Using social media is an indispensable source of entertainment for everyone today. One of the most popular global social networks in Vietnam is Facebook. However, some users still encounter Facebook access issues on various browsers on phones and computers. So what are the solutions for this basic problem? Let’s explore in the following article.
Troubleshooting Facebook Access on Mobile Phones
Before proceeding with troubleshooting steps on your phone, check your internet speed. Poor WiFi or 4G signals can slow down your Facebook usage or cause login errors. If your internet connection is fine but you still can’t access Facebook, you may try two solutions below:

Reset your phone and close background apps
Running too many apps simultaneously can cause conflicts, affecting your Facebook browsing experience. This may lead to Facebook not opening properly. The best way to fix this is to close all background apps on your device and reopen Facebook. You can do this in your phone’s settings.
You can also restart your device. This is the quickest method to turn off and restart the system efficiently.
Fix login issues by changing DNS
Open your WiFi settings and select: Modify network -> Show advanced options. Tap on DNS1 – DNS2. Enter one of the following DNS addresses:
- 8.8.8.8 – 8.8.4.4
- 208.67.222.222 – 208.67.220.220
Finally, press Save to complete the setup. Restart your WiFi and reconnect to Facebook on your phone.
