The biggest tip that can be given is, if you have the right equipment to do so, plug in mouse and keyboard, or a controller. Performing the simplest actions, such as looking around and walking, can be irritating with mobile controls.
If you aren’t worried about Achievements or cheating in general, you can change the difficulty or mode at any time in the settings. If you’re not relatively close to a Water source at your home, it’s a good idea to make is an unlimited Water source nearby. This can be done by digging a 2x2 (only need to be one block deep) hole and placing a Water Bucket in one corner of the hole, then dumping another into the block diagonal to the one you filled. When you do this, you can get Water from it without having to refill it forever.
