Stop Wi-Fi from dropping

Go to Settings>>Wi-Fi, then tap the three vertical dot icon in the upper-right corner and select "Advanced" or "Advanced Wi-Fi." Find the option "Keep Wi-Fi on when screen is off" and set it to "Only when plugged in" or "Always." Get the insider tips to solving four other common Android problems.
