Possessor of a Wave first generation, it is clear that the difference is marked. The S3 reacts quickly, is really fluid at navigation, we feel that the processor of the respondent.
The screen is "great", bright and has an excellent "resolution". The camera is level, for beautiful shots, and recording of videos as bonens qualities (for a mobile phone. That this is not the first utility).
I use quite "random" phone (surfing, applications, and appeals ...), but I confess that the battery holds up well charge for a smartphone (2 days on average).
I have of course yet exploited all the specifics of this phone, but after a month of use, I admit to not being disappointed with my purchase. The move is the environment "Bada" to "Android" is a pleasure.
If I still had to reproach it would be on the aesthetic appearance of S3. For this price, Samsung could have made an effort in terms of quality of materials (some brushed aluminum instead of plastic shell would have been nice, and a more sophisticated look too ... I think for example the Sony Xperia S bcp best for cheaper).
Finally, as bcp Electronic Products tel. is not free of bugs. As such, it is noted one: it is not recommendable to "import" contacts via Bluetooth, Facebook, Gmail & co ... Indeed, after importing "pleased" my contacts from my Wave, as well as Gmail, I simply had tt "bad" surprise retrieve the error "processus.com android phone stopped" during calls made and received from these "imported contacts" ... Embarrassing for such. portable. Solution found on the net community re-register "manually" Samsung ts ... Thank contacts synchronization. Besides, I'd like Samsung seizes this pb, because apparently bcp S3 are affected by this bug, a small SHIFT OS would not be too much.
That, ultimately (and despite this little bug), I am satisfied with my purchase and recommend this product (but I give 4/5 and not 5/5 in relation to the bug and the "look" not at the price).
