My missus has the galaxy s and i have the galaxy s 2... I have tried and liked lots of HTCs but the s2 is where its at for me!
Judging by the latest argue between Apple and Samsung about slide function I choose the originality of HTC. But Samsung galaxy is also pretty machine and there are a lot of beautiful functions in it.
But OP didn't ask about LG Optimus. Samsung Galaxy is the one you should buy. Its got everything and thus Best Smartphone in the World.
Samsung galaxy has some very good features and even easy touch experience but you can not compete with HTC when planning for Android Phones ....
Samsung is far better than the htc and you can refer to the latest addition to the basket of Samsung, i.e. Samsung Galaxy Note
I have a Samsung Galaxy S2 for about 4 months now after having a HTC Wildfire before and let me tell you that the speed and power of the Galaxy S2 is amazing. You can really run multiple tasks everything together (music, GPS tracking software while running, surfing, etc. ) all together at the same time. The only bad thing is you need to charge (like every other smartphone) every day! I wish smartphone factories would come up with solar battery covers that will automatically charge your mobile as soon as you turn it around while sitting on a terrace for instance Recommends: Samsung Galaxy S2!
I am using Galaxy S I, it is really a great smartphone which does everything what i expected. It is Samsung Galaxy i prefer
