Minecraft – Expand maximum multiplayer limit

I'm on a Moto G3 too! So far, I have found no way to resolve the issue, but if you find your IP address (in Settings > Wi-Fi > three dots > Advanced [it is the one that usually starts 192]) on the phone you wish to host the world on, and then on the device you want to connect to it, open Minecraft and hit Play > New > tiny plus and arrow > Name (whatever you like) > the IP you found > Port 19132 or whichever port Minecraft suggests to you. On the host device, open a world and make sure LAN sharing is switched on. The world should now appear in the client devices's world list. The same option on the client device should work for any world the host device is on. You should now be able to connect. Hope this helps :)

I have had this issue as well. What I have found seems to work, make certain the host device world setting is shared. Then enter and wait in the setting screen. At this point the other devices should see the host device world (they may have to close and reopen the world selection screen). If this does not work on first try then close and kill the app on hosting device and reopen it. By close and kill you need to double tap the home button and then swipe the app off screen to kill it.

I play all the time with my son and this issue happens a lot. Using this technique has worked almost 100% of time. If you are paranoid you can also flip the WiFi option off and back on again while waiting in the setting screen.
