It's not an easy transition from iOS to Android I'll tell you that.
The Note 2 back is too smooth and you battle with it sliding out of your hands 90% of the time. Comfortable one handed operation is simply not an option, but you don't realise how often one handed operation is vital until the honeymoon period ends.
You can't pop a case on these things either, it's already huge and the slippery design is what allows you to slip it in and out of the pocket with ease. I tried a clear body glove from skinomi and it's certainly helped but your hands need to be a little moist and stylus use is hindered.
Most of my gripes are environmental. Now that I live in a sunny climate, it's too heavy in the pockets when wearing shorts. When I used to drive all the time it was fine but being on a bus, you can't touch it if you're standing. I'm out walking around a lot now too so it's just not a comfortable experience.
If you drive everywhere and mainly stay indoors then it's fine... which is why I've ripped out the SIM card and use mine like a home tablet these days.
I have massive issues with the software side too.
It's great being able to flash new ROMs but each one comes with such massive caveats.
Then you have to deal with fundamental issues with Android itself:
1.) Photos management is in such a poor state with Android, you'll have a million folders based on what app downloaded/made/tweaked the image. I had album art in a few music folders and couldnt even delete them from the album. So good luck finding a new downloaded photo. Some HDR photos don't even appear in the library until a few good minutes after being shot. The single photo folder in iOS dominates.
2.) Group SMS messaging is so excruciatingly buggy in Android, if you're coming from iOS there's no doubt you'll be in group messages with other iPhone users and Android just haven't incorporated a feature that lets you group text without it working one second and messing up the next.
3.) Policed apps in iOS have a massive advantage, apps not only work better than the main website but operate fluidly, very intuitive and to top are aesthetically incredible. Then you look at the Google PlayStore and find a list of awful junk that Joey the 12 year old next door uploaded. Not only that but so many apps are jammed with ads galore and some are even dangerous to your privacy, one actually sent my phone number to an ad firm and they kept calling for three days non stop. What a joke. The key point to take away; people on iOS pay for decent apps so it encourages developers to release A-grade material and the common iPhone hardware makes it that much easier to optimize apps then earn a return when selling it.
4.) The cool tech comes to iOS first. My UP band wasn't supported by Android till two years later, Flipbook was on iOS, Figure, WAZE, Vine, Über, Mint, Teamviewer...
5.) In-app search and download of "free trial" apps, you don't have to prat about with torrents or file transfers.
6.) Games! Goodness me the games!! So many incredible games on iOS that actually make sense on a phone. Android seems to be carried away with a console calibre that look gorgeous but on a mobile platform leaves you with games that just doesn't get played.
I'm fine with putting in a bit of work to get things functional when you pay less for a device but this thing wasn't cheaper it actually cost a lot more than the new iPhone.
Yeah this was definitely a bad choice in my circumstance and I get to regret it for a whole two years till my contract expires.
