The reasons I considered moving:
- support is good
- using the same flagship SoC for all their phones, so even the cheaper models have a good one, this noticeably has an impact on the camera
- in the midrange SE budget, they compete pretty well with price go features
Reasons I ended up not moving:
- accessories that were not really Apple compatible, e.g. Now Samsung watch 3, don't have an interest in paying the premium for all their devices
- certain open source apps I use don't exist on ios as they would not be able to pay for the app store license, I also occasionally make my own apps and don't want to pay for a dev license
- most of their phones are quite expensive and I just don't buy in that price range
- they don't make it easy to repair their devices, parts are difficult to source, and they don't have the best track record in terms of build quality, phones will drop and a glass back for example is not going to be great. It's actually what interests the most about the new S21 line
The rest are just general ios pro/con.
Dont like the lack of a notification drop down, forced grid, and I like android back from right because it's easy to reach on a larger phone. I understand ios not doing so since they designed that app flow is cards, while Android decided that any horizontal swipe means back, both are good options. The settings menu is still atrocious, they need to sort it out.
I do like the general uniformity, the dedicated loud/quiet slider, the attempt at being simple for most core apps, the design language is generally consistent and clean, etc.
