Since Smartphones rely on wireless connection to connect to the internet either via Wi-Fi or data connection, the stability of your connection depends on the strength of the signal you are receiving. If you are connecting to the internet via Wi-Fi, make sure you are not too far from the router.
As you go farther and farther from your router, the Wi-Fi signal you are receiving gets thinner and thinner and this affects the speed and reliability of your connection. To fix the problem of frequent disconnection, move a little closer to your Wi-Fi router to improve the Wi-Fi signal reception.
