Anyone's wifi disconnecting when the screen goes blank? Every time I wake it up it is on lte.
There is no way to revert back to an older os and every oem has its issues. You see more about Samsung because there are more of their phones out in the wild.I bet your on Lollipop. You know half of the questions on Android Central are asking about bugs on some Samsung device. Never seen a Sony or LG. If your on Lollipop go back to KitKat. And there might be a battery saving option that turns of Wi-Fi when the screen is off. Like on my phone. If there is, disable that.
