content: Hey there!Trouble with headphones, won't connect with Android smartphone.My front camera seems to still work, but back mounted camera has been dead, for a year now.Question is, I suppose, maybe that camera doesn't receive IR properly, due to phone's age.With testing two separate wireless headphones, they both act the same, that is the 'connect' sequence starts with the usual tones, that ramp upwards in freq, but that series of musical notes doesn't complete...the headphones produce about 4 out of the total 9 ascending note tones, stopping short of completing.At least that indicates the headphones can make sounds, (but I believe the headphones blinks the LEDs as if indicating error of some sort.Checking settings, (I'm really not a very savvy user), settings ON-OFF etc.When my headphones failed this way, I bought a new pair of wireless headphones.Exact same problem; won't complete the connect, as I hold the button down, as normal wireless Bluetooth connect.I have an Android OP SYSTEM book, but dont know a lot about settings and troubleshooting in general.Any hints, before I sign up for a class ?Thanks.

content: I'm not sure what issue you're having - the title is about bluetooth headphones but you mention your camera? And IR? Why would that stop the camera working?I occassionally had issues with getting bluetooth to connect on my old Samsung S5, but that was a very old phone with an old version of Android. What phone or version of Android are you using?It doesn't really matter if it plays tones on start up, or what the LEDs are doing - unless the headphones manual tells you what the LED flashing indicates - you can test if they're connected by playing music on your phone, or even a youtube video. AFAIK, every version of Android shows a little headphone/hedset symbol on the top right to show if the headphones are connected, and its using a headset profile.If it doesn't show that, but in bluetooth settings it says the device/headest is connected, then tap the cog symbol and delte the device and start again.

content: Its relatively older phone (2020).Things on that Samsung phone are gradually going into failure modes, like only the camera that's on the screen side works. But I assumed the IR of Bluetooth is being sensed by way of camera. There is no dedicated IR sensor, is there ?But thanks, I'll try to look for the headphones symbol, and I did find the ON-OFF in SETTINGS.In theory I should reference my Android for Dummies book, but I found the book lame.

content: Bluetooth has nothing to do with IR or your camera. It uses radio waves.It is necessary to pair bluetooth devices. Normally one has to initiate this paring by opening the phones bluetooth settings and look for devices. Select a device and pair it. Might need a button press on the headphone. These kind of procedures are normally listed in the manuals, but with cheap stuff it might be in a foreign language.

content: Ah, interesting!The Bluetooth ON-OFF is on same page where my phone also lists the headphones:MUZ4002. So I will try again, this time will try poke finger (i.e. 'select') right on that brand name, along with the usual on-off.I know about pressing and holding the center button, right there on the rt. side headphone itself. Thanks

content: You may need to delete all saved Bluetooth devices from the phone's memory and try pairing the headphones again. Although if the phone is old, as you say, maybe it's a sign that it's time to replace it?I don't get what the rear camera and IR signal do with it... Although if the camera doesn't work either, that's another reason to get yourself a new phone! )))
