I also started using a Galaxy S6 last week after I dropped my Iphone 5S and broke its glass.
First day: I will buy another Iphone (checking Iphone prices and contracts)
Second day: Actually, may be I can use Galaxy S6 until Iphone 8 is released.
Third day: Transferred my contacts from Iphone to Samsung and set up most of the app I use on Samsung.
...
Currently : Still living with Samsung:
- I have problems with Samsung's keyboard. Lots of misspells.
- I am still not used to the Android back button.
- Fingerprint scanner is a nightmare on S6.
- I am still looking for the Iphone side button.
- Camera is better on S6.
