High frecuency noise when charging - Galaxy Tab S2 Q&A, Help & Troubleshooting

Hi guys, after one moths with this tablet I have to say that this is an amazing product, but I have noticed recently that my tablet makes a high pitched noise when I use any earphones and it's own charger at the same time, and if I touch the metal frame disappears, but this is annoying to touch the tablet all the time I listen to music, my S2 tab is a sm t710, dou you have the same issue with your tablet? Is this and a reason to return this one?

[Q] Bluetooth transmission power

Hi everyone,
My first droid phone Xperia X8 has a wired headset with control buttons. I used it and I was happy.
Yesterday I have bought an Ace. It doesn't have a headset, and now I use Prolife BT55 bluetooth headset.
So, the problem is:
Headphones' BT receiver is located at the right speaker.
When I'm sitting and holding Ace in my hands, the sound is fine.
When I'm standing and Ace is in the left pocket of my jeans (using the left pocket is a many years habit and i'm unable to change it), the sound randomly interrupts for 1-2 sec.
I'm 178 cm high, not a giant
This is definitely not the phone lags because the song continues playing and I just don't hear it for 1-2 sec. And it's not my headset problem, because it receives music from my laptop without interruptions at up to 10m.
As i think it's not normal, and the problem is very low power of phone bluetooth transmitter.
How can I increase the power of Ace's BT transmitter?
i dont think this is a problem of the ace
i use a dell bh200 bluetooth headset, i have no such problems
i even get decent signal strength keeping my mobile in my backpack/pocket

[Q] Samsung Dock audio 'POP' problem

Hi Guys
I have my Notes dock connected to a pair of active studio monitor speakers (Cakewalk). When the 3.5mm audio jack is connected to the Notes 3.5mm out on the top of the phone all is well.
When I connect via the docks 3.5mm out (and set the Notes audio to dock out) I get an audible 'pop' from the speakers when the screen is touched - seems like a surge of power from the sound card audilbe from the USB but not from the phones own 3.5mm out.
When the phone is awake using fairly regular touches there are no pops, only when it is dormant for a few seconds does it make you jump out of your skin
I have had the same set up running perfectly using an HTC HD2 and Kidiggi docking cradle.
I don't know if it is the Dock or my Galaxy Note at fault
Any help is appreciated

I'm experiencing the same issue.
Audio ouput through the Note's own 3.5mm jack is popping as well. Doesn't matter whether I'm using passive headphones or an active speaker.
The Note I had before I got a replacement had this too, so it seems to be a general problem :/
Edit:
Forgot to say that it seems that the speaker output gets disabled when there is no sound for about 2 seconds. As soon as something makes a sound the speaker gets enabled again and produces the popping sound.
So while listening to some music or watching videos there is no popping at all. Only when the playback starts.
I have the same problem with my SGN. It's much more noticable, when I connect car charger, but without it it's still there, but u need to focus to hear it. Any of you found solution to this?

[Q] Pop/click after sound played

Just got a new Moto G 2gen 4G. Very nice phone.
However, it has a noticeable annoyance. After a sound has been played, such as a keyboard press, or locking/unlocking the phone, a hiss can be heard in the speakers and after a second or two a popping/clicking sound occurs. It sounds like the audio circuitry is 'powered down'. With headphones, the behavior is the same, but hardly noticeable.
I have not noticed this with other phones before. My Nexus 7 however has the same problem on further inspection, but I hadn't noticed it before, probable because the speaker is located at the back of the tablet and the sound is a little quieter.
Is this normal? I have been researching the problem on the internet, but didn't come to a conclusion.
Any of you guys notice the same behavior? Or have a solution?

Samsung Level U Pro - BT Headphones - Wow

Picked these up on Amazon for £70, main reason was level app gives all the function and tuning sound to suit plus the two speaker per earpiece design.
Cut to the chase stunning sound. I am picky with around 10 pairs of headphones ranging from Sony, Beats to AT. Also an ex audiophile coming from full on active Naim Audio system. Reason for mentioning that was the way Naim exerts grip, control, detail and ease rarely phased.
This sums up the headphones, never experienced this sort of deep controlled taut bass on headphones coupled with a clear midrange- normally one ruins the other.
The sound level when you attach the right size buds is shockingly loud - at max phone and headset zero distortion.
Plus you get all the notifications and crap s voice. Can take calls not tried says has two microphones.
Negatives, neck surround it very hard and stiff, ear buds do not totally seal and on my set BT occasionally disconnects but worst of all an ongoing BT skip every 15 - 30 seconds.
Hope I can solve the connectivity as even my cheap mpow have zero BT issues.
All that said an awesome headset.
Update: Reset the level U and unpaired, then repaired - all sorted NO BT connectivity issues, also have my Gear S2 and Car BT connected this morning.
Wore it to work, forgot I had it on as it was just hanging on my shoulders, realised when it vibrated (notifications).
Tried a few call, very good, I prefer to use it with 1 earpiece, mic quality (has 2) seems very good to the other party.
What about battery life?
Not really timed it but on a full charge 6 days ago have had 5hrs use in the app still shows more than half.

Bought this unit today and paired with Axon 7 Mini and instantly hated the sound and volume level.....of course i was driving away from the store and just had to try it. I immediately put the headset on my center console in my car and left it till i finished up my other activities and didn't touch it till i got home and downloaded the Level app from the play store. Pulled up reviews on amazon,and Headfi and saw people raving about the sound quality,put my laptop down and started going through my settings on the phone players(Neutron,Poweramp beta,and built in ZTE hi res player)......then setup Samsung Level app and changed the silicone tips to a set that fit my ears perfectly and then .....DAMN ! These things DO sound amazing. The quality of the drivers is beyond what i expected and the volume is just perfect....I love to crank it up,but my ears have been damaged through playing in live bands and crazy loud car stereos,and the volume was loud but not painfully so....These are keepers and sound great with the Dolby Atmos turned on. My two cents .....great deal when you find these now for $39.99

XTRONS hissing/buzzing after Alpine upgrade Audi TT Mk2

Hi all,
I recently swapped the original Audi TT concert Radio for an XTRONS (the one that looks like an RNSE Reference Number is IB79ATTRP). Now the Unit works very well, especially after the modded Amp was installed. Yesterday I swapped the original Speakers and Amp with an original Audi Sound Plus System (by ALPINE). The sound quality boost is immense, though it is creating a hissing sound that is constant all the time. It wasn't there prior and when I turn the unit off it is gone, so I guess it is a problem with the XTRONS. When I crank the music up it is not really noticeable, but when the music is low it is very annoying.
I don't really want to drive around blasting music 24/7
Any help is much appreciated!
What did reseller suggest when contacted for support. What has been tried from the other threads in MTCD section (if your unit is an MTCD)
Teh crickets.

I wonder if you were able to fix the buzzing noise. I installed the xtrons 10in and I have kinda the same issue. When I turn on the headlights it lowers the buzzing noise down significantly. I thought it might have been my JBL amp so I tried lowering it but its still there just lower.
