For currently equivalent to 300 EUR unbeatably good

I use the S3 for a year now and am super happy.
Meanwhile, you get it for EUR 300; since it is still technically absolutely perfect, this is a excellent price performance ratio.
Although it is almost exclusively made of plastic, the workmanship is impeccable.
Despite the size it is very light.
The display is crisp and sharp, great colors and excellent contrast.
Operation is extremely liquid, clear liquid than on my Google Nexus. 7
WLAN signal strength (150Mbit gross no problem) excellent and UMTS.
Camera is great outdoors or in daylight, pictures and HD videos 1a; in the dark, the quality significantly.
Class: you can choose the battery and there is a lot of accessories on the market.

I've been using the device, as I said, every day for a year, even outdoors (including navigation while hiking and cycling), and never had any problems or difficulties. I listen to music (MP3, Radio), browse the Internet, take pictures and videos, use Email, SMS, Facebook, Skype, Lync, use the device as a FB for TV / receiver / player, etc., and in addition to the use as an address book organizer, calendar, translator, etc., etc.. I telephone of course. Everything went fine and I would buy the S3 immediately.

News and officially obtained by Samsung Android 4.1.2 for the S3 - 4.2 it is expected to be no more and instead is then available from December / January to all appearances the version 4.3 available. This means that the Samsung S3 not neglected as before.

As a memory extension, I use a 32 GB SanDisk Ultra micro SD Card (net 29.71 GB) - funkioniert properly, absolute compatibility.

Oh yes, the device used in my car (VW Passat) via Bluetooth connected to the VW RNS315 - also works great; among other things, can read my contacts on RNS315 and play my MP3s on the SD card in the S3 via the car audio system - full compatibility here. Also navigation by Navigon app is going very well.

Today I received the software update to Android 4.3 Jelly Bean. The installation has worked flawlessly. Many things (for example, settings and menus) now look different and clearer and much has improved at first glance (eg the e-mail client). The most important thing: Everything (incl. My apps) will continue to function. The specific changes I must, however, look more closely to me.
