    From iPhone to Flip

    I am a long-time iPhone user, fully entrenched in the 'ecosystem', but this is the phone that lured me back to android. I tried out the Z Flip 3 last year but went back to my iPhone pretty quickly because the camera and battery were severely lacking, however Samsung seems to have fixed those problems with the latest model. I am so in love with this phone! I'm almost overwhelmed with how much I can do with it compared to iOS, and I'm very impressed with how far android has come in the past few years. Samsung too, it has all the same neat little quality-of-life 'smart' features that I enjoyed on iOS. All the same features are there under different menus, literally the only things I'm missing is imessage and shared albums, and there are ways around those. As I mentioned, camera & battery life have been greatly improved. I'm only on day 2 so my phone is still settling and optimising, and I'm only down to 42% after 12 hours off the charger. Granted I am not a very heavy user, but I do use GPS and play Pokemon Go which are pretty battery-hungry so I'm impressed. The battery life should only get better after a week or two when it finishes learning my usage habits. See kitten pic for camera example :D I'm REALLY impressed with night mode, it's actually better than my iPhone. I had a 14 plus before this and the flip takes clearer, less noisy pics in both light and dark settings. I'm no pro photographer or anything but it's more than good enough for me. Let's not forget the coolness factor either. This phone is seriously SO COOL! My mom & aunt, both tech-phobic old ladies, have been oohing and aahing over my cool new phone. They're like "how does that screen bend?!" Lol. It's so nice just having a flip phone again too. I'm old myself and all my first cell phones were flips, this phone brings back so many good memories it's ridiculous. I love being able to fit my phone in even the smallest pockets too. Well done, Samsung, well done.

    Samsung Z 4 flip

    I have been team iPhone for about 10 years now, And I always refused to make the switch. I saw commercials and advertising for this samsung flip and I entertained the idea of getting it, but what made me finally do it is that my iPhone had 64g and Samsung obviously Holds way more gigabits than iPhone. With that being said, it was easy to switch and I LOVE this samsung flip!!!! It reminds me of a Nintendo’s ds lol. The graphics, the customization, the storage space and just overall how much easier and more private samsung is compared to iPhone. I highly recommend!
