Cell phones forum: iPhone or Samsung S3

1) If your stereo, car stereo and Yamaha stereo dock are proprietary, i.e. have dock connectors/interfaces for iPhone, you would have to acquire different equipment. There may be a few exceptions if your equipment also handles USB connections. I've seen a couple decks where you could at least charge via USB but not play back music ,etc. YMMV.

2) Correct. Samsung runs Android so does not work with iTunes/App store.

3) Yes, if there are sufficient Android apps written for your device. Look in the Android marketplace.

4) I've yet to have to deal with one personally, but they're out there. I don't feel most users need an AV program though. YMMV.

5) Not necessarily, depending on what problems you have (or don't have) with the stock handset & apps/features that come preloaded. Keep in mind that some cannot be removed since they may be part of a carrier ROM. I like to buy unlocked handsets if this ever becomes an issue. $$$.

See iphone has its own market demand and S3 has its own....lastly its an individual verdict that which one is the way to go for?
For your concern i would tells you that iphone and S3 both can do all the things you are looking for, but iphone is short handed in terms of connectivity with other devices whereas S3 don't. Hence, considering this fact finalize your decision.

first, dont buy samsung s3, go ahead with iphone 5s because iphone 5s is really made for humans. first full sensar based technologyused in iphone 5s.

anyways
dont worry about malware and spywares. The samsungs3 defined them itself.

I have both an Android device and an Apple iPhone on my account. I think an Android device is the better choice. This is only my opinion and I won't try to convince anyone otherwise. Both devices have benefits and drawbacks, but I wouldn't say that either type is "superior" to the other. I suggest that the OP talk to friends and relatives for more opinions. Good luck, OP..

And since I grew up when the best PC was the TRS-80 the fiddliness of Android is fine by me. The iPhone feels more polished but the openness of Android even with it's issues means I went that way.
