I think this thread is still going to be around.
So after being the biggest Samsung fan boy I'm going to switch over and get an iPhone.
My Galaxy S - Perfect
Galaxy S3 - Great
Galaxy S4 - Suburb
Note 3 - Wonderful
I've had a note 4 now for about 4 months and it's a piece of shit. My first note 4 had a slew of problems but the most annoying one was that the main camera wouldn't focus. It was a common issue so I warrantied the phone and got a new one. It's even worse. Tons of calls go to voicemail, gps is broken, camera is still broken, messages lost or people receive 2-6 copies of the same text from me. I've tried different roms, flashes and resets and I'm done.
