I just came back to Apple from the Galaxy s5. I have been an Apple fan since the original iPhone came out. Early last year, I made the stupid decision to go for the bigger screen and move to Android. I was lulled by the high screen resolutions, pixels, graphics, customizability ....blah blah. The phone was pretty cool in the beginning. However, the hype of the new "features" and "gimmicks" wore off quickly. Those new things I thought were cool to have only worked half the time and I never ended up using them much anyway. Unless I rooted my phone, I was unable to get that bloatware off. In the end, all it did was slow down my device considerably.
4 months into the phone I was FINALLY able to update to Lollipop. Weeks after the update, it was increasingly becoming difficult to make phone calls or text. The phone would freeze, lock up, and force close in the middle of typing or reading.
As the frustration continued, I decided to wipe my device and start over fresh. That lasted 4 days. Then it was back to the freezing, locking up, and force closing.
I was fed up. I went to Best Buy and forked over the extra money to become eligible to get the new 6+. My wife and I switched to Apple and I have never looked back. I missed the usability, simplicity, and using something that "just worked".
Bottom line is I made a mistake I will never make again. Apple all the way.
