[Q] Faint buzzing/electrical noise during high CPU load? - Xperia Z4 Tablet Q&A, Help & Troubleshooting

Anyone noticed a faint buzzing/electrical noise during high CPU load?
I have the Sony Style Cover SCR32 as well, this cover seems to make it even worse (might have something to do with the magnetic lock?)
Sometimes I can even hear it while scrolling in Chrome.
If I put my ear to the top of the tablet (where the SCR32 lock is located, just above the front camera) the noise is almost always present.
It sounds very similar to what’s described in:
http://forum.xda-developers.com/shield-tablet/help/quiet-hissing-electrical-buzzing-tablet-t2939814
So could this be a “normal” thing for this tablet or should I consider returning it?

i don't suffer from any buzzing noise but I would be really keen to get your feedback on the SCR32

Thanks for the feedback, I returned mine today =)
Didn’t like the heat/throttling either so I´m probably going to wait for SD820 instead.
I posted some thought about the SCR32:

Anyone feels that the volume from speakers are not balance

At first couple days I did not notice this issue, yesterday I found the the sound from the right speaker is louder than the left one. Anyone has the same feeling? I'm not sure if it is a problem with the hardware or the software.
I did notice something like that yesterday. Don't know if it was what I was watching, or if it was the Tablet, but it does warrant some more investigation.

I can say I don't have this issue. I had originally thought mine was the other way around but then realized it was my audio source, sounds balanced now.
Have you checked with earbuds to make sure that it's really a problem? I've found that not only where I hold the tablet in relation to the side speakers will effect the perceived balance, but also how I hold my hands which changes how sound reflects off them thus changing the perceived sound balance.
Earbuds worked with no problems. I'm thinking it should be the speakers' issue.

My sound is off, but that was after I opened up my device. The speaker wire is close to the edge and are a bit flimsy - just moving them slightly seems to affect the volume. Could be a hardware defect that affects some devices more than others, that's my guess.
At one point, I had actually put some electrical tape over one speaker as my "DIY" volume reduction fix.
I've had my gtablet for about five days. The left speaker would sometimes work, but mostly would not. I tried different ROMs, different media players. Earphones worked perfectly. Sending it back for a replacement... I'll just end up breaking something else if I open the thing up, lol.

[Q] Mono speaker is freaking me out! Am I the only one?

Hi Prime users,
I'm a litte surprised there are no threads about this here.
I'm pleased with the general audio quality - feels a little like force feedback in games
BUT
I am totally irritated by the fact that the audio only comes from the right edge of the Prime. This is really driving my ears crazy.
What about you? Use headphones? External speakers? Got used to it?
I'd just like to know how you think on this one.
Regards,
pintness
It bothers me as well.
I didn't care really.. I agree that it would be better to have speakers like the TF101 (1 on each side).
I love the sound quality, but yeah it is uncomfortable unless you watch videos in portrait mode.
it bothers me a little bit. Mainly when I'm playing back something with sound and I can barely hear it due it's single speaker blowing out from the back.
From a design standpoint, ASUS should have at least included the left speaker on the left-bottom of the Keyboard Dock. It would have made more sense, making the tablet whole with it's keyboard dock accessory than not including no left channel audio at all. But oh well.
in fact it is a stereo speaker

Indeed it is, but without proper stereo separation it is a little bizarre.

But... why would Asus do that? I mean, if they put in stereo speakers, why not put them in correct place? This looks like a really poor design decision to me.
If only they would put more effort into function than design...
I have an Acer Iconia A500, which has stereo speaker on the back, too.
General problem with those is that treble sounds aren't reflected well and you can't hear them at all, except when you hold the tablet in that ONE special position and form a cone with your hands.
At first it really bothered me (coming from the TF101) but now I can manage...
The quality IS a whole lot better compared to TF101 though, making up for it. Still really no idea what they were thinking here though.
I agree...weird but it is excellent quality.
I am more bothered by the fact that the speaker faces away from the user instead of towards the user. This means that most of the volume the tablet can put out is wasted unless you have some kind of sound reflector behind the tablet.
I know this is common among thin touchscreen devices, but to me it never stops being a source of minor annoyance.

therefore it is NOT stereo but mono.
Come on, that's audio 101. If it's outputing both left and right channel from one single speaker it's NOT Stereo.

There are two speakers ... they just are side-by-side under that single perforation.
Lame I know, but ....
What I would have liked is to have the dock have speakers integrated (facing "up") with some separation.
That way, the tab alone could service headphones, but when docked and sitting open, it would have a better stereo experience without headphones.
definitely found it pretty weird for awhile but used to it now.
If I'm on the road, I use my headphones to block out sound and avoid annoying others.
If I'm at home, I'll plug it into my stereo speakers. If I ever use the built-in speaker, it's probably for unimportant stuff that doesn't really require good sound quality.
Never a problem
Posted this elsewhere, but I haven't seen anyone mentioning it, so perhaps it bears repeating:

This is sort of a tangent, but if you're just holding the Prime and viewing/listening to something yourself, the way you hold the Prime can make a significant difference in how loud it is. The speaker is right at the right hand edge, if you hold it where the speaker is, and sorta cup your hand around the speaker grill, you can direct the sound to reflect off your hand and bounce it towards yourself.
It works surprisingly well and there's no need to install/root or whatever.

^ It helps.
Official cover
The thing that annoys me the most is that if you have the official Asus origami cover and use the flat slightly angled fold, it covers the speaker. And yes I agree that having the speaker face away from the user is a bizarre idea.
I found it hard not to cover it when holding in landscape, but once adjusting it actually sounds pretty good.
I think the quality is pretty impressive. Maybe a benefit from B&O working on their laptops.
I've found if you hold it in the right hand landscape mode then with a certain position it reflects the sound so that it appears to come from the left too.
To be honest if watching a film I would probably switch to headphones.

[Q] Build Quality of the SGSIII

Dear Friends,
I have a problem with my SGSIII
When I tap a bit stronger on the upper half of the screen the frame makes a quiet but audible cracking sound creaking/squeak sound. When I squeeze the top part of the frame tightly with both fingers and tap again the noise while tapping is gone. It seems that the frame is a bit loose. Can you please check if there is a noise difference between when you tap strongly on the lower half of the screen as opposed to the upper part?
This is very annoying when working with the phone and occasionally tapping a bit harder to bring down the notification bar.
EDIT: Don't get me wrong here, the sound is not very loud, it's a slight "clicking" sound for the lack of a better description but it's definitely hardware based. When i tap softer I won't hear it.
I am bummed out that such a premium phone fails on such basic criteria.
Would be delighted to hear your thoughts.
If it's not the same with you and the sound of tapping is the same on every part of the screen then I will return the phone.
Make sure your battery cover is on completely. If it is, return phone. It should not creak, crack etc.
So you are saying that wherever on the screen you tap you cannot hear a difference? I took off the bat cover and still I hear a slight clicking sound when I tap on the upper half.... It's going to be such a hasstle to return it
Sounds fine to me, and honestly is the least creaky Samsung phone I ever owned.
Crap, it really sucks that I have to return it now because I have to send it back manually and wait another week to get the replacement
ADDITIONAL QUESTION: Do you have any problem pink screens or other colors on white saturation? But please keep checking if the creaking sound is present on your device. tap the notification bar hard and listen if there is a difference. I am worried that If I xchange I get a bad screen and then I have to xchange again. Arghh! it's always that decision between 2 evils ..
I can hear a sound when I tap the earpiece, but it sounds more like a rattle from the camera's auto focus mechanism. If that Is the sound, I'd say it's relatively normal.
Don't worry its normal. Typical Samsung build quality.

There will always be haters, build quality is what i expected after owning an sgs2, Samsung prefer light agile handsets over bricks you could hammer nails in with. Treat it with respect and it will be perfectly fine.
Excellent review of build and quality by XDA member here .

Mine seems perfect. No creaking, no rattles, perfect screen. A friend had an iP4 delivered that had marks under the screen, and another had one with loose glass on the back!

Does Lumia 920 have a design flaw?

I noticed the same thing on the iPhone. Both phones have their speakers on the bottom of the phone. What does this mean? When you hold the phone in landscape to play games and grip it in gaming grip, the base of your forefinger (first finger) covers the speakers and muffles the sound. I noticed this a lot playing games on my old iPhone. Speaker should be on the back ideally or on the sides.

use headphones
I haven't seen one up close yet, but I thought the power plug was on the bottom now. So, would that be in addition to the speakers on the bottom?? or did they move them elsewhere?

Thank you for your wonderful useful tip. So I am only allowed to play a game with sound when I plug in headphones. Great practical advice from you! I like to see you hold the phone with the headphone plug digging into your finger too! I know because I made a mockup of the phone and held it in gaming grip.

The speakers are on the bottom of the phone on either side of the USB port.
It would be more practical on the back but in terms of design it looks uglier. That's why they put the speakers on the bottom. My Atrix has its speaker on the back and it is much better than when I had an iPhone.
Speakers never bothered me on the iphone 4s when I had it for 6 months so I don't see it as a design flaw here. I am terribly concerned about the size and weight though. I know that the older Lumia phones are thicker but it definitely does not look that way. The 920 looks HUGE and that is saying a lot since I currently have a GS3.
I hope that my concerns disappear after handling or I might have to get an HTC 8x, which I really want to avoid after owning two crappy HTC One X phones.
Personally I kind of like the thickness. Gives it substance. I have held ultra thin phones and think that I'll break them. Speaker placement to me doesn't matter as long as they sound good. I just hope it's more water tolerable than the L900. Saw the torture test on c|net and it wasn't pretty.

Just on one side, the other side is the mic.

No, tboy is right. They are on both sides.
The 800 also has the speaker on the bottom. It doesn't bother me since I have a light grip on it when I play.
Anyway I think there are always some problems with the placement of the speakers. There is just no perfect solution. If you put it on the back then some people will complain that the sound will get muffled while it's placed on it's back e.g on the bed or the couch. If you wanna put it on the side then you are forced to put one on both sides but most windows phones have 3-4 buttons on one side and adding a speaker would make it look really cluttered and one may end up being muffled again. Top has the same problem as bottom and front wouldn't just work because of aesthetics.
I personally think that the speakers on the bottom are the lesser evil compared to the other options.
The speaker is placed on the bottom is actually a good idea.
With the iPhone it was placed on the bottom due to the alarm, so that the sound would not get blocked.
I always place my phone (s3) upside down just to hear my alarm better , Since I'm a deep sleeper.
The Lumia 920 has no flaws. It was designed hand manufactured by the hand of god. Just kidding. Speaker placement is actually very fine with me. It's more of a preference issue that you brought up. Cnet's torture test of the 900 shows that it will die from water. That should be an indication of what to expect. Then again, it's the only phone I know that you can hammer a nail with and still be fine. The 920 is supposed to be even tougher. So if my phone drowns... At lest I'll still be able to fix thins around the house with it. LOL. Most indestructible phone design I've seen so far was the Galaxy S3. Survive a washer cycle with ease.

Frame of S3 makes noise while holding - design fault?

i found a weird behaviour: If i hold the tab with my left hand and lay pressure with my thumb on the red marked area (just under the keyboard connector), i can push slightly "into" the frame and hear a click noise. i tested it and if you press gently in this area, it makes this sound. the rest of the frame feels fine. it's really annoying for me, cause i have constantly this clicking sound if i don't hold the tab perfectly still with my left hand. i have tested some other tabs in a store and they have the same behaviour - can you verify this? seems like a design fault to me.
Edit: sorry can't link the picture

I don't have this issue on my tablet, the entire border is solid and doesn't move the slightest. Also no click noises. Mabye it was a faulty batch. Perhaps you could contact Samsung and let them know. At least they'll be aware that this is an issue with some tablets
