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 an 8125 with the 2.17 ROM. When trying to stream audio using WiFi and my 820 bluetooth headphones, the blutooth connect breaks after about 5 seconds and cannot be re-established until a reboot. If I stream using GPRS the bluetooth works fine. Can WiFi and Bluetooth normally be used together or is there something wrong on my unit?
They are supposed to be able to work together concurrently but sometimes there can be conflict with the signals.
One thing you can try is to set your wireless router to use a different wifi channel to the one you are on now and see if it makes things any better.
It won't work
I have tried everything. Re-installed everything. Turned things off, turned things on. Nothing corrects the problem. Motorola says to disable the phone connection to relsolve the problem. That does not work either. The Bluetooth A2DP is not working right. Maybe it is the ROM I am using. It is simply 2.17. Is there a bug in that one and should I reflash with a newer one?
I just got a TMOUS HD2 and had the same problems a lot of other people are having connecting it to my car. It connects to the car correctly, downloads the address book, but no sound comes through the cars speakers and the call doesn't register on the cars phone display. I searched XDA and there seems to be a bunch of registry change posts that don't seem to work all the time and disable some features. By doing the following I get it to work consistently with all the features enabled.
1) Turn off the data connection and Bluetooth in Comm Mgr
2) Turn on Bluetooth and connect (or pair) the phone with the car
3) Make a call
4) While in the call, turn the data connection back on
It works for my Land Rover RRS and stays working until I reset the phone. After I reset, I just go through the above procedure again.
I don't know if it works for every car make but it should work for most Volvos, Jaguars, and Land Rovers since most of them use common bluetooth systems.
Hope this helps somebody.
I am having the same issue. I have to manually connect the music stream. The phone stream always connects. Hoping for a fix from T-Mobile.

My car doesn't support A2DP - the phone's separate from the audio head. All the car's phone features work though - voice recognition, conference calling, transfer to and from the handset, and address book and digit dial. I wouldn't hold my breath for a fix though. It's the WIDCOMM Bluetooth stack that HTC started using with the TP2 so there are over a year's worth of complaints logged with HTC and no sign of a fix.
well, not much to be said for the Microsoft bluetooth stack either. I have a 2010 LR4 and can't get my HTC Raphael/Touch Pro/Fuze to keep a connection. Hard to know what the problem is, starting a WiFi or GPS session often resets the connection, in addition to the random drops, sometimes mid-call.
When I tried an iPhone though, it worked fine, naturally.
I am having a very odd issue with my X10. My phone crashes when ever I am on my bluetooth headset and trying to use any app that accesses the internet through wifi.
Crash scenario: I take a call on my headset. While on the call, I try to use an app that tries to access the net over wifi (i.e., gmail, facebook, email, calendar, or browser), but the app would hang or not be able to get access. I end the call and still no traffic.
- 1. I go to the settings menu and it's super slow to access any options. I get to the wifi settings and the phone freezes. I have to shut down via power button.
- 2. I go to the stock wifi widget and turn wifi off to restart it. A crash occurs and the phone reboots itself.
Possible causes: Conflicting hardware. Software bug. One or more hardware failure.
I have used the BT headset with my SE P1i and SE X1a. Both work perfectly with the headset. Both phones connect to the same wifi router without incident also.
I've tried to solve this problem all day now and I'm out of ideas. To think that such a glitch is possible boggles my mind. If anyone can give me any input, I would greatly appreciate it.
Hardware I'm using:
Phone: SE X10i
Headset: Jawbone Prime BT headset
Router: Linksys WRT120N (Rev. Unkown)
I am finding that sometimes my DI will not connect to a headset it is already paired with even if the device. For example, my home phone has Bluetooth built into it so that my calling my cell phone makes my home phone ring. However I generally have to manually go into Settings -> Wireless & Network -> Bluetooth settings and then manually connect to that device.
Sometimes that doesn't even work and even when I click "Scan for devices" nothing happens. I have to power off my phone and then power it back on for it to work.
It is a big pain because I will be in my car and put on my Bluetooth headset and it won't work automatically. Not fun to have to restart the phone just to get Bluetooth to work.
Any thoughts?
I've used BT headsets since the Moto V710 came to VZW.
Some phones are better than others at connecting, and the Incredible seems slightly better than the Moto Droid - or maybe about the same.
Examples (and I use a few different headsets):
I answer the phone normally and decide to switch to a headset. I power on my headset and stick it on my ear. After a few seconds I hear the "connecting" noises thru the headset and the audio switches over from phone to the headset automatically.
This is what happens most of the time. Now sometimes I do this process but nothing happens. So I then press (usually long-press, depending on the particular headset) the button on the headset to "make" it connect. Sometimes, though not very often, even this doesn't work (after trying several times) - in that case I power off the headset (not the phone!) and power it back on again and repeat.
If I turn on the headset before making a call, I have close to 100% success rate for my headset connecting normally.
This is about par for the course as far as Bluetooth goes. Some phones are better than others - and the top of the line dumb phones I've used seemed to connect a little more consistently than the various smartphones I've used.
As to your issues, if your home phone BT thing doesn't have a button to help "force" the connection, then maybe just try powering off/on BT on your phone instead of powering the phone off.
Yes i have the same problems. Not unique to the Incredible though. Just about every smartphone I've had does the same BS.
The iPhone is the only phone that worked greater than 90% of the time. Wish the Incredible was better.
Thanks for your input guys.
Coming from experiences as a long time Windows Mobile user, I never had any problems with this. I think with Windows Mobile it automatically connected to whatever Bluetooth device it had already been paired with something like 98% of the time. With this phone it is honestly 50% at the best.
I want to clarify here though that it is not just it being flakey. There is definitely something that happens with the software on the phone. How I know this is that when I have this happen and it is not connecting to any Bluetooth devices, I will go into Settings and when I press the scan for devices button, nothing at all happens. Normally it would appear to be searching.
Something is definitely happening (or not happening) and I haven't narrowed it down to figure out what it is.
I use BT headset in my truck all the time. I turn on BT before I get into the truck and turn on the headset after I am in the truck. Takes a few moments to connect.
Works every time. Only real issue is lack of hands free dialing, but if I know I will be calling someone while driving, I pre-dial the number and can with a long press on the headset redial after I am driving.
Answer the phone is not an issue.
I have the same problem.
Xlink BT gateway at home, Moto H790 headset for use in the car.
My other phones auto connect (or I get a prompt on the phone asking if I want to connect based on BT Security settings on the phone).
My HTC Incredible will sometimes auto connect, but if I disconnect the H790, it doesn't auto connect to the Xlink. If I got into Settings on the INC, and select the Xlink to connect to, the INC will tell me it failed. Same if I try to reconnect the H790.
I have to power the INC off/on.
This is unlike my other phones and Blackberries. (NOTE: I didn't try my droid with the Xlink, but it seemed to connect/disconnect/reconnect fine with my H790, unlike my INC which doesn't).

Yep, KidJoe, that does sound exactly the same. Glad to see I am not crazy. If you find a solution, post it to this thread please. I'll do the same.
Same problem here.....The MyTouch I had was 100% reliable when picking up the BT when in and out of range. I think I want a MyTouch with a 4.25 inch screen.
I have this strange issue with my G4
It's my workphone and i use it in my van with hotspot-starter app.
i get in the car, turn on ignition and my phone connects to the inbuild handsfree system.
The hotspot-starter app toggles the hotspot so my tablet wich running navigation has internet for live traffic information......
This worked flawless with my previous phone but with my G4 the tablet won't stay connected to the phones hotspot, it keeps connecting and disconnecting every minute or so. But when i toggle bluetooth off and on again everything works fine and keeps working without any problem.
It seems like if the bluetooth connection is made before the hotspot is turned on, the hotspot fails to maintain a connection....

Interesting; haven't seen this. A possible workaround is to use Bluetooth tethering vs a WiFi hotspot to deliver internet connectivity to the tablet. Works great, connects faster and has a side benefit of consuming less juice on both ends. I use a similar config due to the crappy G4P GPS receiver.
Is it possible to use 2 bt connections simultaniously?
Handsfree set and tether to the tablet?

Give it a shot. It is certainly possible to establish multiple BT connections simultaneously. I occasionally use a BT keyboard, mouse and speaker with a cheap Amazon tablet. Doesn't miss a beat.
OK..... I got bluetooth connection made between phone and tab, checked bt tether on both devices otherwise it won't connect at all....... But no internet passtrough ?

Hum, sorry to hear that. Make sure WiFi is disabled on the tab. Have to believe the fault lies with the tablet as I'm able to successfully tether several different devices (individually) to my G4P via BT. Works a treat and cuts power drain on the G4P by half meaning I don't have to keep it on charge during longer trips.
