Wifi direct - Galaxy S II Q&A, Help & Troubleshooting

Why is wifi direct implementation on galaxy s2 is different from galaxy s3? On gs2 when using wifi direct it disconnects you from access point but on gs3 it doesn't. Does it mean gs3 has more antennas?

Galaxy s3 microphone problem?

Just tried to do gchat with a galaxy nexus with the phones next to each other and the galaxy s3 emits a loud screeching sound, like 2 microphones that were to close to each other. This only occurred with the s3 while the nexus had no problems. Anyone have any thoughts on this?

Did the same thing with a iTouch we tried on. I'm curious if it had to do with being on the same WiFi.

Shouldn't be. S3 was using 4g while nexus was on WiFi.... so I'm assuming I'm not the only one? Can anyone else add on to this?

They are probably giving each other feedback. Try having one phone in one room and one in another. The problem will probably disappear.

It does disappear when I'm in another room. But I guess it's a little disturbing that only the gs3 will get feedback but the nexus won't. Guess no Google hangout with multiple phones in the same room....although I don't see the purpose of that.

You can use Skype, Google talk and others as long as you have a 3G or wifi signal. The tab can send normal cellular sms too.

Is there any chance of calling over GSM network ?

With tab 10.1 no. Tab 2 10.1 has a GSM calling capability though.

Ah man I want a galaxy 2 tablet instead of galaxy 1
I didn't know that about the version 2. I hope people use hands-free but I'd love to see someone holding 10.1" against their head.
