Hahahaha, well while we were in the store, I was trying real hard to remain neutral, despite the fact she knows I'm an avid Android user. Turns out the stylus on the Note 9 is what sold her on it.
Personally, I don't love how expensive these flagship phones have gotten, but having the Samsung VR headset, and loving that experience, I'm kinda stuck with the flagship Samsungs if I want the VR capability. The S9 is a HUGE improvement over the S7 in terms of VR.
Yeah I held onto my Galaxy S4 for like 3 generations, so I know how frustrating it can be to still be using a 4 year old phone, haha. I did notice though, that doing a factory restore on it every so often really helped breathe new life back into it. Also, if yours has a removable battery, get a new one for that sucker. A healthy battery can also really help improve a phone.
Believe me, these cars have a habit of growing on their owners. Your feelings will only strengthen over time...
