I have a Samsung Galaxy A8 (2018) and everything works fine. The wifi is okay when I stream on Netflix, watch youtube, do video calls, and any other internet related activities. But as soon as I launch an online game, the wifi suddenly drops instantly and when I exit the game, the wifi goes back to its strong signal.
I tried connecting to another wifi network and everything works fine except when connecting to my home wifi. So I assumed there must be something wrong with our router, but then I tried to play the exact same games on different devices connected on my home wifi, and everything is okay EXCEPT for my device.
I already tried the following:
- restore my device to factory default
- restart my wifi router
No luck. Can anyone help me?
