Regarding WhatsApp, it is probably best to use iCareFone or Move to iOS.So I’ve recently made the switch going the other way. Been an Android user for years and my last iPhone was the 5. I was using an Oppo Find X2, but picked up an iPhone 7 and Apple Watch series 2 in the classifieds for good prices. The watch was one of the main reasons I was thinking of moving over.
The only problems I encountered during setup were getting text messages and What’sApp transferred to the iPhone. I couldn’t figure the texts out so lost all of those, and I had to buy a bit of software to move over WhatsApp properly and keep the messages.
In general use though I’m rally liking iOS. I’ve got a work issued iPad anyway so was fairly familiar with it, but I still just needed to find my way around. It’s doing everything I want it to do though and I really like the partnership with the watch. Again that just seems to work well too.
The only issue I haven’t figured out is audio in the car. My old phone had a headphone socket so I could just plug it in, but iPhones don’t so I’ve had to dig out my old iPod. I’d rather use my iPhone as I use it for sat nav too, but my car is old so the head unit doesn’t have Bluetooth.
Perhaps, I could help. What audio inputs have you got and how do you like to listen to your music?
