The best phone for a long time

I have a new contract with Vodafone abegschlossen plus I got the phone as "addition".
My previous phone was the Samsung Galaxy S2 and which is the same I noticed from the beginning that the designs are very similar.
The A5 is about 2cm longer than the S2 but it even thinner.

I'm going to make a Pro / Contra List.
Alsoooo:

+ Call quality is really good
+ The screen resolution is perfectly fine for me, so I can not see any pixels
+ The contrast and the colors of the screen are typical OLED bit too colorful for as many tastes,
but I love this screen technology.
+ The system runs smoother than a lot still in S2, so no stuttering or anything
+ What I like very much the Multi Window feature. Where you can use two apps simultaneously
+ With the two cameras I am satisfied on the whole,

-The Camera blurred very quickly because no image stabilizer is present.
-The Back is in my opinion fall for something smooth.

What might disturb some buyers would be the case not that open.

After a battery test, I can say that it default software has been well solved,
there is a normal energy-saving mode and an "Ultra" energy-saving mode.
In said ultra-energy-saving mode, the phone switches to a different user interface, and there are fewer
Functions.
