Ideas on Diagnosing Bluetooth? - General Questions and Answers

I am having an incredibly frustrating issue and I am hoping someone may have some insight?
I have a Sennheiser Presence bluetooth headset. The headset worked very well for many months. Then, at a certain point, it just stopped being recognized or discoverable by my phone (Galaxy S7). I tried updating firmware, resetting the phone, wiping cache on phone, rebooting in safe mode, etc. Nothing worked.
The company sent me a replacement unit which started out working, and then after several weeks also stopped working. I have now gone through this 3 different times and each time its the same - works for several weeks then suddenly seems to stop. On the one hand, maybe its a hardware problem with the headset. On the other hand, I have read reviews on Amazon, googled, etc. and havent seen anyone else reporting this kind pf problem so I feel like maybe there is something going on specific to my device.
I cant figure out what else to check or do and I wonder if anyone has this experience or suggestions/ideas?

By the way, my other headset (Plantronics) doesnt have the problem - it is discoverable and can pair. It is just the Sennheiser.

Frustrating Video Out/TV Out Behavior

Hi, everyone.
I searched for this and didn't find anything, but it's a little hard to know what to search for.
I use WunderRadio to listen to Internet radio. A few weeks ago, the Video Out (TV Out) screen started popping up at random times, usually when I was tapping something on the menu or on the screen. When it did, it was almost impossible to close and it really messed up my listening.
Some days it wasn't too bad. Sometimes, when it got really frustrating, a soft reset would stop it temporarily (or at least slow it down). When it was at its worst, though, nothing helped, and it was impossible to listen to WunderRadio.
It wasn't only in WunderRadio that this would happen--it would pop up occasionally in other applications, as well. But it was the most frustrating by far in WunderRadio.
I recently did a hard reset, so I only had a few applications installed. I first assumed that this was being caused by WunderRadio, so I uninstalled it. I still kept seeing that Video Out screen.
I selectively uninstalled applications and thought a couple of times that I had identified a program that was causing the problem. However, it kept coming back, seemingly regardless of what was installed or uninstalled.
A few days ago, this stopped happening. I haven't seen the Video Out screen a single time. I don't know if it has fixed itself (I doubt it) or whether it will suddenly reappear.
At this point, it seems like this could be due to faulty software, firmware, or hardware.
In July, I had a similar thing going on. I don't know if it was related to this or if this is just a coincidence. The phone all of sudden decided that it wanted to redial the last number called--over and over again! I would think I had it stopped, put the phone in my pocket, and get a call from a contact asking if I had called them. No, I hadn't, but my phone had!
As with the Video Out problem, sometimes a soft reset would help. Often, however, I ended up just having to turn the phone off for a few hours, then cross my fingers and try again.
With both of these problem, I was hesitant to send the phone in for warranty repair, because they were both so unpredictable that the repair shop would probably be unable to make either of these symptoms appear. My fears have since been borne out by the fact that both problems seem to have been solved--at least semi-permanently.
On the other hand, either or both of these problems could come back at any time!
Can anyone tell me what's going on here and what I can do about it?
Thanks in advance!
Are you using a wired headset? Maybe the pins are a little off and acting like the tvout cable USB pins and that's triggering it.
You should try to think if there is any correlation between a wire headset and this activity.
Also, do you actually use TV-out? You can just disable it entirely by a registry tweak so it won't be able to popup if that helps.
If you need anything further feel free to PM me since it's unlikely I'll find this post again
Good point! Yes, I am using a wired headset--most often when I'm listening to WunderRadio--which would explain why it happens most often when I'm listening.
I switched from headphones to earphones the other day, and that could very well be the reason it's no longer happening.
It's either the headphones or your USB port that's bad. But since you've said the problem has went away with new headphones, I'd say it's those. But it's a guaranteed hardware issue, although not necessarily the phone.
I had the same problem - TP would switch to TV Out mode randomly when mini usb was used (either charge or headphones). Mine needed a new usb socket, although I think theyyyyy jutssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssst swap the whole board. And I know it's off topic but can someone point me in the right direction to sort out my keyboard problem above?!

hehe does your keyboard repeat too quick? Settings - Personal - Buttons and reduce the repeat rates on 'up/down control'...on and stop eating so much candy while playing with your phone

Galaxy S6 Bluetooth stuttering issues

I want to take a minute and share a bluetooth issue I've had with my Galaxy S6. Maybe others have observed the same thing, and while I'm not specifically looking for a solution, suggestions are welcome. The S6 is about 3 months old, Andriod 5.0.2, unrooted, and other than Apex launcher pretty vanilla.
For the record, with the exception of the issue I'm about to describe, this phone has been phenomenal.
I use the phone in my car over bluetooth to and from work every day. For the first two months this worked great, no problems at all with podcast addict or poweramp. Then, I noticed the audio would dip momentarily. As if someone turned the volume down and back up. The bluetooth connection never gets lost, just the audio dip. Then, eventually the problem became perpetual. I will describe the symptom the best I can, as if the volume were being turned up and down. This wasn't the case, more like the bluetooth stream was somehow going away and coming back.
I tried all the obvious things, like re-pair the phone to the car, clear the bluetooth cache, Volume Up + Home + Power button and then "wipe cache partition". As a last resort I did a factory reset. This last step actually solved the issue, for a while. This was a few days ago, but this morning I noticed the same periodic blips in the sound, so I suspect over time the same problem will once again return.
<rant>
I was in touch with Samsungs customer support, who is supposed to "values you as a customer and want to insure that we have provided you with the answer you were looking for". Unfortunately, the blunt truth was they ended up being useless with an offer to allow me to send my 2 month old phone to them and wait for an undisclosed time, for what might end up being a refurbed replacement.
</rant>
Since I don't see mention of this in the forums, maybe it's not a wide spread problem. Maybe a compatibility problem between these two specific chipsets? Whatever the issue, hopefully some future update comes out that fixes things. Defaulting the phone every few months would be a considerable drag.

My bluetooth keeps turning on/off continuously

I have my phone paired to my Pioneer head unit and if it disconnects it will occasionally cause the Bluetooth to turn on and off continuously without warning or anyway to stop the cycle. The only way I found to resolve the issue was a factory reset. I just reset my phone yesterday and the same thing happened today when I tried to re-pair to it again after I left my car. As you can imagine, this is extremely annoying, I am hoping someone can provide some insight on a possible fix for this.
Blu Pure XL

I've experienced the same thing with my BLU Pure XL. It doesn't look like anyone has responded; likely because there isn't a fix and the phone is so substandard. Bluetooth is weak; signal strength is pathetic, cheap glass, lacks friendly ergonomics. I could go on. I've tried to submit issues through BLU website - no response. I won't give them another chance. Likely will buy the new Plus 1. Good luck and if you find a fix please post it here.

So I noticed the Bluetooth issue only occurs for me when I am connected to a bluetooth device and a specific sequence of events occurs to cause it to happen. Specifically something like my vehicles aftermarket Pioneer radio where I can wipe the bluetooth memory of it (it has a 3 device limit). If, I wipe the bluetooth memory of my radio while my phone is connected, it will cause it to go into a loop and thus require a factory reset to resolve the issue. Since I discovered this, I have wiped the memory while the phone is disconnected and the issue does not occur. It has been quite sometime since I have originally posted here and I haven't had a problem since I have monitored it. Please let me know if this seems to be the same thing that occurred for you as well. Cheers

Phone audio stopped working with bluetooth

Hey guys I have searched around here but cannot find the answer. I have now tried 3 different methods of pairing my nexus 5 and it refuses to work properly with the phone audio. It HAS worked in the past. When you look at the pairing you can click the wheel on my phone settings and you cannot tick the box that says "phone audio". I have had the same experience with my car bluetooth, an older plantronics 520 earpiece and now a brand new Motorola Roadster 2. I have gone as far as to factory restore my N5 to no avail. I even went back to an older factory image (M4B30X) and it doesn't make a difference. I am currently on M4B30Z. What else could it be? I don't want to use this as a reason to buy a newer phone but holy crap this is frustrating. If anyone has any feedback I would love to hear.
Thanks,

Faulty speaker or bad bluetooth connection?

Several months ago I got an Insignia Alarm Clock/Speaker from Best Buy. It was $20 bucks - a total steal! It sounded great and has been working fine.
However, in the last week, whenever I play music from my tablet or phone every the music will skip or stutter. I have not done anything new to the tablet or speaker that would cause this (that I know of). The phone seems to play the music for longer before there's an issue, but not by much. Weirdly, I've noticed it's more prone to dropping out during a quiet lull in the music. I listen to a lot of instrumental music and whenever one instrument is playing alone, like a piano, it almost seems like the speaker mutes itself inbetween notes. It's hard to explain and super bizarre.
I've tried restarting the speaker, the tablet, reconnecting the Bluetooth - nothing has worked so far. My tablet is fairly old - a Galaxy Tab S - but my phone is a brand new Pixel 3 XL. It'd be odd if the speaker was failing already, but at least it'd be some kind of explanation. It's driving me bonkers. I can post some recordings of what I'm hearing if that will help anyone understand what I mean.
Any suggestions would be greatly appreciated!

Try booting to recovery and wipe the cache partition, if that doesn't solve the issue then the issue is deeper or it might be because the speaker has low quality hardware/software(doubtful, but possible). More than likely, it's something else that you have installed on the device(s) causing this. You can try booting your phone or tablet into "safe mode", this mode only loads the preinstalled app that came with the device, if the issue is not present while in safe mode, then you know it's caused by something that you installed. If it is still present while booted into safe mode, then it might be caused by something that came pre-installed on the device running in the background, youd have to start experimenting by disabling system apps until you find the culprit causing the issue.
NOTE: Disabling system apps can cause serious issues with device functionality so be careful which ones you disable.
