Wifi: in the whole apartment 100%, 1 & 1 FritzBox. Reception: O2, Karlsruhe south, at the window 100%, otherwise 1-3 bar. Battery: after 3 days, 1-2 hours per day still use 53%. The S3 Neo is here an EU version. So multilingual. A variant with NFC, thus no dual SIM card. In delivery condition with a protective film. Wearing no protective pouch is not recommended. Very sensitive even with freshly washed hands and beautifully smooth everywhere. That nobody needs with the APPs is a "allemana" disease and very annoying. Of the 16 GB of memory are about 12.5 GB. The rear door is very thin, so carefully remove with. Only a little lift in the gap, and then slide your finger nail side around. Actually for 170 trouble-free phone, but the apps, the smooth surface and the lost memory ... 3 stars for the trick. 04/18/2015: Because GPS module only 1 star. I assume that the modules have in S3 NEO, here just GPS, not a quality standard. It is reingeschustert which is just to have inexpensive on the market. No recommendation for the S3 NEO more.
