I own a Samsung Galaxy S3 for 4 months now and never regret buying one.
The screen is huge, have a good battery life and is powerful.
The voice calls is crystal clear and maybe sometimes too loud on full volume.
The GPS is really impressive and very fast.
From the moment I switch the GPS on to locate my position took about 5 seconds outdoors.
Indoors it take about 10 seconds.
The WI-FI radio is excellent.
I receive a signal from my Wireless router (Dentra) indoors trough 4 walls, with a distance of about 20 meters without problems.
I rarely use it's Bluetooth radio.
And it is customizable.
I can change the screens with what ever I want.
And to crown it all there is a lot of apps on the Google Play.
And many of them are for free.
So, if you can afford it, buy the S3......wait a moment, the S4 is due out sometime in this week.
Just one cautionary note about the S3....buy a protective casing that can flip open and close.
Mine have a magnetic strip that close the strip holding the case .
Although the glass is scratch resistance, it can scratch if you are not taking care..
I tried to scratch a broken S3 glass with a very sharp knife, and it just do not scratch.
And never drop it.......you will almost certainty crack the screen.
Ask my friend.:facepalm:
The only downfall is the PC to Smartphone software.
Do not bother installing Kies.......it is a PITA.
Instead use something else or Windows Explorer. I use "My Phone Explorer"
Otherwise looking for the Nokia range.
They also make good phones.
Oh yes the memory of the S3 can also be expanded to a max of 64 GB with a micro SD card.
The camera is a 8 MP, with HD video recording which in my opinion is suburb.
