In the past I used iPhones, from the 4 to the 6s. At that point in time, Apple was ahead of Android, both in hardware and software (remember the Galaxy S5 bandage meme). But now Android is ahead in both areas...and still is cheaper.
I still use an iPad and prefer it to its Android rivals...but I have to say (since we’re talking about Galaxy Notes and business usage) the Apple files app is a complete mess. Google alternatives (Files and Drive) are so much better...and Microsoft. So all seems fixed...but wait! Because Apple is Apple, you can’t change the default Files app! ??????????????????
