Since I am well versed in the area of law I helped my son when ordering.
Everything went smoothly and perfectly first time.
The Ace runs so far without any problems.
The overall quality impression is very good.
The capacitive touch screen works perfectly and has a good picture quality.
The integrated camera also makes pretty good photos, even a photo light is integrated.
WiFi works also very good, Ace also uses the 802.11n standard, which is currently the most powerful, longest range.
For technical problems you should not always make the hardware (mobile) charge, depending on the software (apps) -Konstellation, it can of course times have problems - but that's not the PC differently ...
Conclusion:
I think that Samsung Galaxy Ace S5830i super.
Everything works as it should.
The quality is, Samsung usual, very good.
The size of 3.5 inch displays I find absolutely okay but that is certainly a matter of taste
I highly recommend it!
