For me it was important a replaceable battery (this has 2540mAh) and holds loose with "normal usage" 3 Days by. With little use (mainly standby) sometimes even 4-5Tage! Absolut top. My 2 year old Nokia with the same usage was wide after just one day. Charging takes on average ca.1-2,5Std. depending on the remaining capacity. The memory can be expanded to 32GB.
The smartphone is with its 5-inch IPS display well in the hand and can also be good with one hand. It has no side control buttons for on / off, volume up / down. The lie for this device on the back. Maybe a little unusual but I got used to it quickly. Man can wake the phone by tapping the on / off switch at the rear or through 2xKlopfen on the display, which I find quite funny. And it works flawlessly. The screen responds very quickly and the rest is truly brilliant and in no way claiming or milky blurred as some users. Maybe even remove the protective film :-)
The understanding when making calls is good and the built-in speakers is also sufficient. If yes no hi-fi system.
Reception problems I had not until then. Offering under perhaps the provider if there are problems.
Bluetooth, GPS also without problems. The TomTom Navigation App runs better than my separate navigation system.
The sync with my Google account (address, phone number, calendar, etc.) worked also excellent. Update, settings and synchronization lasted about 1 hour. Everything perfect.
If you have ever had an Android smartphone should therefore actually have no problems with my Android 4.4 is too cluttered. Too many submenus. The 4.2 I found clearer. Well, but in order to get clear.
The display reacts very quickly to commands and programs to run without problems. Videos run without stuttering.
The camera takes pretty decent images for a smartphone. In low light, the quality decreases. But that's with most smartphone that. But the absolute Hammer are videos! They are absolutely brilliant and razor sharp. I have adjusted the settings for photo and video to the highest level. It's worth it!
I am happy and satisfied with this phone and would highly recommend it !!!

There are users who say mobile data traffic can not be switched off. What a nonsense !!! Basically it can be on any smartphone mobile data traffic deactivate! Just the manual reading when you have no idea!
A reviewer writes his display was milky. Because I would sometimes remove the protective film, or if that does not help go to Fielmann!
