I do two different types of tutorials here. The generic tips, which can be found here, are intended to be used on virtually any Android smartphone or tablet that it supports. Then I create guides that are specific to an individual smartphone. Some of them are interchangeable (many Galaxy S10 tips work on the Galaxy Note 10, for example) but you will be assured that the tutorial you’re reading will work on the smartphone you own.
If you would like to see support added for a particular smartphone or tablet, please support the cause and donate so that I can afford to purchase additional devices (I pay for each of these out of my own pocket).
