One advice: it's a ll about the computer OS you work with.
Mac OS with android is as horrible as it can get. Faulty sync, almost no settings, iPhoto integration is horrible with every android device I owned. None of the android device producers have a fully working app. OK, Sammafiasung devices I haven't owned for years, but HTC, Sony and Google only have half working apps. iPhoto Sync is horrible with almost all of them. They don't sync at all, the sync all photos into one folder, they sync only fullsized photos taking up to 20MB of storage for one photo and so on. It's not fun at all to sync an android device with a Mac. Esp media.
Windows f.e. has quite a good, but instable app which at least syncs iPhoto libraries and downsize photos.
Sizewise do you guys know what 3mm in thickness means? It's a difference like day and night when it comes to handling a big device.
The monster Xperia Z Ultra with it's 6,4 display was very good to use because of the only 6,5mm thin device. It was a pleasure to hold for such a big device. 10mm is totally outdated.
