Let’s just be thorough in troubleshooting your phone and let’s not skip a solution that could potentially fix the problem. The next thing you have to do is to reset all settings in your device.

This will delete the system cache and replace it with a new one. The case is actually a collection of many files that’s used by the system to make your phone run smoothly. There are times, however, when these files get corrupted and when it happens, performance issues may occur and affect some functions and this could be the reason why WiFi keeps dropping on your Galaxy A40. So, wipe the cache partition and see if the problem continues after it:

Sixth solution: Backup your files and reset your phone

A master reset will fix this problem provided it’s not a hardware issue. However, we’re always hesitant to suggest this without exhausting all possible solutions first as you may lose some important files and data. But this time, it seems like you don’t have much of a choice so create a backup of your files and then remove your Google and Samsung account so that  you won’t be locked out of your device after the reset. Once you’ve done all these, follow these steps to reset your phone: 

  1. Turn off the device.
  2. Press and hold the Volume Up and Power keys.
  3. When the Galaxy A40 logo shows, release all three keys.
  4. Your Galaxy A40 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step.
