Create a claim on how android is better than apple. Do your research on improvements throughout the years to android phones unlike the apple (iPhone) kind. With this, you'll be able to back up your claim with evidence and reasoning by further explaining your found evidence. (In your own words though.) For example, a Samsung (Android) and an iPhone 10 perhaps (or any kind) and start comparing and contrasting things that are alike between the two, things that are different from one another, and even so; you could investigate their profit changes. From people switching to android more often than iPhone (or vice-versa).
