I've been using the SGS2 for a good few days now and really loving it. However, I've noticed an intermittent problem with the Bluetooth and WiFi.
WiFi problem:
I have connected my phone to my home WiFi but sometimes it does not connect when I get in range or after turning on my WiFi on the phone. If I then go to settings and long hold on my WiFi connection and then select 'Connect to network' it will then obtain an IP address and connect. This is intermittent and doesn't happen all the time. I would say the problem occurs more than 50% of the time.
Bluetooth problem:
I have a Motorola S9-HD bluetooth stereo headphones. I mainly use it when watching videos and listening to audio books. I already have it paired so when I turn it on, it should connect and play all audio through them. When I click the play button, it should fire up Winamp and start playing the last audio file I was playing at the exact location it last played up to. The SGS2 sometimes fails to fully connect. I have to find the device in the Bluetooth list and long hold and then select connect to network. Again, this happens around 50% of the time. Occasionally, even when it has connected, it still does not play audio through headset (but the audio isn't even played through phone). Switching off headset and switching back on normally resolves it.
Both scenarios work pretty much flawlessly on my SGS1. Also, both Bluetooth and WiFi problems seem related as they are so similar.
Anyone else having similar issues or could explain why this might be happening on the SGS2?
Well, BT & WiFi both use frequencies in the 2.4 GHz range, so if you're using both simultaneously, they may be interfering with each other. You might try setting up your WiFi to use a different channel; your router's config pages should allow for that. Or you can use a 802.11a connection if your network supports it; that uses the 5 GHz band, so it won't interfere with BT.

No, not using them at the same time. I use WiFi when I'm at home and only use my Bluetooth headset when I'm out. WiFi is turned off on the phone when I leave home so it shouldn't doesn't interfere. The other thing is that everything works fine when I do the same with my SGS1 so the only change is my SGS2 handset.
If there is WiFi or Bluetooth interference then why does it not exhibit on the SGS1?
I did try rebooting the phone and power cycling the headphones initially but this didn't work. Strangely it all started working after a phone reboot and has been working perfectly since.

Hello, I have a smiliar ussue. I have the Samsung Galaxy S2 and when I am using the bluetooth for listening to music in my car ( I have a Ford Focus with bluetooth), the music plays and stops all the time. I've try it with lots of programs and does the same thing with all. Also with any king of bluettoth speaker.
Did you solved the problem?
Thank you.
I have the At&t Xperia Play, still completely stock, haven't had bootloader unlocked or installed any custom roms. Not sure if anyone else has been having these issues, I'm trying to figure out if my phone is defective or if the xperia plays have crappy bluetooth or maybe just the stock bluetooth is crap.
Anyways, I use my bluetooth to connect to the car stereo and stream music. The bluetooth on this phone never connects automatically. Sometimes it will connect for phone audio but not for media audio, I always have to go in and adjust it, or turn off bluetooth and turn it back on to get it to connect. Sometimes it just refuses to connect for anything until I turn bluetooth off and back on. My old Samsung Vibrant worked perfect, connected instantly no issues at all, even the Iphone 3gs had no issues and connected instantly. Another thing if/when the phone does connect, it takes awhile to connect, usually at least 30sec to a min before it connects.
Anyone have any suggestions or think the bluetooth radio on the phone may just be defective?
I'm having a strange problem on my Nexus 4 phone. I have a Plantronics Voyager Pro bluetooth headset. It's one of the originals that only supports phone audio, not media audio. The phone runs pure unrooted stock Android 4.2.2. I'm currently connected to my home wifi network. If I make a phone call with the headset the audio becomes very choppy. Then the phone automatically disables wifi and falls back to AT&T's cellular network for data. After that the audio through the bluetooth headset is perfectly fine. Is this normal behavior? Is it not possible to have data over wifi while using bluetooth?
This is an issue discussed and reported humongous times. Hopefully Google will resolve it in coming update(s).
I have read countless issues with Samsung devices when using bluetooth the wifi dies or becomes very erratic.
This is a new device I pair a Bluetooth Keyboard and the wifi disconnects. or is very slow then disconnects, etc.
Everything I read talks about Sidesync but I don't see it in the list of installed apps.
Am I missing something else?
Hi There, since July update I have serious bluetooth issues.
As also reported by other users when you want to share the internet connection (tethering) via bluetooth the bluetooth app crashs.
it es even reproducable.
So as I was not able anymore to tether and bring my car online (toyota touch and go) I tried to switch to Wifi Hotspot, which works fine.
however yesterday I recognized that when Wifi hotspot is activated audio streaming via bluetooth is interrupted every few seconds.
anybody else here with same experience?
any workarounds avaialble?
how can I create a bug report and submit to Xiaomi, is this even possible?
thanks
and brgds
