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 :)
If you're looking to save your world, there are two methods:
- Wait 3 seconds - Minecraft PE, just like the PC version auto-saves every few seconds.^
- Open the pause menu and select "Save and Quit".
This can be accessed by pressing the Back system button at the bottom of your screen.
On some devices, there should be a pause button next to the chat button (top-right of the screen)
^ Note: This only applies to the player's inventory.
If you're looking to transfer your files between Android devices, you can find your world saves in the following location:
/sdcard0/games/com.mojang/minecraftWorlds/...
The following directory can only be accessed with a file explorer such as Explorer.
You do not need to have a rooted system.
Alternatively, simply plugging in your android device into a computer as an MTP device should allow you to access the files directly. Just go into the games/com.mojang/minecraftWorlds folder as your default root folder when accessing through USB is your sdcard0 folder, which can be found at:
/root/storage/sdcard0/...
Lastly, note that sometimes, that your sdcard0 folder may be called sdcard for devices without a Micro SD or SD card slot, or that your world folders may be in the sdcard1 (or higher numbers) if you have set your default (non-legacy) app data location to store to your SD cards (if any).
On iOS, you can access all add-on data (ie. world templates, texture/behavior packs) and world save data by accessing the Minecraft App's shared files via iTunes.
Alternatively, they can be found here:
./Documents/...
in Minecraft's app domain (sandboxed data allocation).

For the textures, you can easily change it by changing the terrain.png file with your desired texture pack. But beware that PC's terrain.png may vary with PE's. Try searching for a similar or exact texture on the Minecraft Forums. They have lots of ported texture pack.
For maps, you will need to first port it because MCPE maps aren't infinite and a portion of the world will need to be cut, pasted and then saved in MCPE format. Then you can transfer it to your Android device.
Note: My previous answer was for iOS devices. I have changed my answer to fit the question and hope it helps.
