Hi
Recently my UK TF201 has begun making an intermittent croaking noise. It does this at totally irregular timings and often without any user activity occurring at the time.
My Prime is stock and not rooted. It is not associated with any particular program or app running in the background and is becoming very annoying. I'm writing this now after having been woken up by one of the croak sounding noises.
Look forward to your recommendations.

Please post a video
I'd love to be able to, as this would have saved me having to write the description as best I could. Unfortunately though, it makes the noise only a couple of times a day. Often just the one chirp/croak sound but occasionaly it will put out a couple within a second or two of the first. I don't have the time or a memory card large enough to sit with recording, waiting for it to croak before editting it down for a video I'm afraid.
It isn't exactly like a frogs "ribbit", its more or a deep "ugggh" but my children refer to it as croaking.
I've heard an identical sound before from a friends laptop, which he brought round to show me. It made these random noises a couple of times a day for about a fortnight, before it crashed and died. I hope these symptoms are not an indicator of a similar fate for my lovely Prime.

Yea I was thinking it was probably random, so it'd be hard to catch on film. That's so odd though. Doesn't look like anyone has any idea, since no one has posted. Does it come out of the speaker, or resonate out of the whole device? Does it do it if it's completely shut off?
Thanks for the reply Jay.
I'm darned if I can tell where the noise comes from. It's occurred a number of times whilst I've been using it but unfortunately with the speaker located on the back it is difficult to know whether it's from within the unit or speaker generated. Personally, I'm 99% confident it's from the speaker, it's just the 1% I can't fully confirm.
With regard to whether it happens with the unit shutdown, I rarely do a full shutdown other than once a week and then only for a full restart. It hasn't been left off for a long period to monitor. However it does this random chirping when in use and when in standby (screen switched ogg). Sorry can't be any more descriptive.
Mine does it some times. Nothing to be worried about tho...
That sound is typical from CPUs. Some laptops/desktops do that sound too.
There was a case from some Dell XPS that were doing that sound so loud that you could hear your CPU even with the internal fan at full speed.. they were offering a free CPU change for these users.
Sometimes my laptop does that sound too (AMD Phenom II X4) and my gfs laptops (Intel i5). I have yet to find what triggers it... but all my machines have done it.
Thanks Zephyrot
Yes that's exactly the noise. The laptop that my friend had was a Dell XPS 1210. Perhaps it was just a coincidence then that the laptop died a couple of weeks after it starting making this noise.
The noise that occurs usually at least once an hour has not occurred in the 2 hours that I have had it totally down powered for investigation. This therefore also lends itself to your theory that it could be CPU based.
The problem I'm having though is that it is loud enough to wake me up when it erupts with one of these chirp/croaks. If someone actually knows why the internals make this noise and more importantly what can be done to stop it from occurring, I would be grateful.
I appreciate that down powering is an option but this is not something that I had intended to do with a tablet. I use my table at work and need to get access to it within 15 seconds of picking it up. Turning the screen off and with such a good battery life, I can readily access information on the fly, whereas having to turn it on would mean waiting up to 2 minutes which is just too long I'm afraid.
Is there anything else you can add Zephyrot with regard to describing the noise, or diagnosing that you have done for the rest of the community to be able to comment on?

There is obviously an animal stuck in your tablet, probably small frog or bird. I would RMA immediately before the animal dies.

Hello,
I know, I know... old problem, yet there is still no definite answer to the question of continous random freezes. My HD2 is also experiencing them (worked fine for about 3 months, during which it never fell down whatsoever)
but!!!
I knew from a few days before the first freeze that something was wrong. The bottom of the phone was getting incredibly warm while heavily using the hardware (watching HD vids, browsing web etc.) Me being stupid did not think of it till today. So once again, knowing that my HD2 would freeze, I plugged it in to recharge the battery. This time - enlightened by the thought of old overheating problem - I put it right next to the opened window - it was -1 *C outside. Results? No freeze! Battery fully charged for the first time without a random reset! In my case this is definitely temperature-related problem, it could possibly not be just mine.
The question is: How to lower the temperature? I don't feel like using my phone in a fridge or moving to subpolar areas.
EDIT @28.02
So far my theory is correct. Once I kept the screen on for 10 minutes and was far enough away from the window, the phone restarted itself (and I was not abusing the hardware; I was, in fact, just writing a text message.) Normally it would shut down right after the attempt to load and stabilize the main screen, but since I put it right next to the window at the PIN window, it cooled down and now works fine again.

Maybe it is the battery, you could try an inexpensive replacement one from ebay.
Well, ebay is off the limits for me, but I will surely try some cheaper counterpart. It's been over a week and thus far my theory is proving to be correct - low temperature = no freezes.
The heat might also be caused by lots of stuff running in the background - have you checked this out as well?
Of course I did - Task Manager is one of the 3 apps on the main screen. I always make sure nothing is running, be it an app, or an unnecessary process.
But yes, some of the applications do increase the temperature, however I find that normal... well, as long as the heat does not make my HD2 shut down!
EDIT @ 09.03:
Waiting for a new batt to arrive. I just hope this is just some minor energy output problem and that's why my hd2 is overheating, leading to shutting down.
Got my new battery from a pretty decent company. Normally after turning off the phone and even reattaching the battery I'd have problems turning it on again (would have took me several attempts); however this time it went very smooth.
Any update on use with the new battery? I have the same overheating/screen lock problem with my HD2. Mine has done so after taking a call and having the phone up to my ear for several minutes.
Unfortunately it wasn't the battery. The most common circumstances in which my HD2 freezes is trying to use the internet, followed by playing music from the Sense player. The only thing left to do is to return it.
I declare HTC HD2 and the HTC tech support piece of junk.
Final edit:
Sold my HD2 and bought Desire HD. <3 Android!
Dear all,
I've been waiting a little before rooting and installing a new ROM to make sure I don't need to return my phone for any reason. (So, it is stock now, no root, locked bootloader, KNOX still there, etc.)
So, far I've noticed three small problems, which I don't know if they are universal or just mine:
Sometimes when I get a call, the touch screen is irresponsive. If I press the lock/power button twice, it seems to work again. (I now have set up to press home to answer.)
It often feels a bit warm, more than I'd expect. (I have it in a case, though, a Spigen Slim Armor. It fits perfectly though.) But this happens sometimes when it is just sitting, not playing games. It is not really hot, but I can feel it warm in my pocket.
Sometimes I get a pop between songs. See this post
(So, at least one person also has the last problem.)
I can live with any of the problems above, but I'd hesitate to have a defective unit which can have bigger problems later on. Is any of the above an issue for you? Any suggestions if I should exchange the phone?
Thanks!
Luis
Do you remember when were the times when the screen was unresponsive?
I've read somewhere that sometimes when the screen is woken up and is under some pressure this will happen, and the only way is to do what you did. It's not uncommon in touchscreen phones though, so I wouldn't worry about it.
The verge app was broken until the most recent app update. Also, the s5 seems to refuse allowing Dashlane's accessibility service from working properly. So no more auto filling passwords for me. Ugh. I hoped rooting might help but it didn't. Now I really can't wait for custom ROMs to start appearing. Samsung, you make great hardware (like amoled displays) but your software sucks. Even the software on my Samsung TV is stupid.
Yes on two out of three!

The unresponsive screen is more than a little issue, it is being reported all over the web, and get's more severe over time. I'm thinking that it is a bad proximity sensor defect, either firmware, hardware or software. Some people are reporting along with myself that sometimes for no apparent reason, the screen will not turn on even though the phone is completely operational! This has happened to me four times now and I am stock with very few apps on my phone, five total games and Pandora. I do use a substitute launcher that I've used for years but I don't believe that would be the issue since others report the same issue with stock launcher.
The pop or skipping you speak of in sound happens to many of us who stream music in our automobiles. It even happens on the note3. The fix is simple for that one though! Turn the screen on. I was told that with many of the streaming software music programs that the phones CPU goes to sleep and does not offer enough processing power to the music program. I stream all day via bluetooth to my Auto's sound system and it will usually start to skip, click or whatever after the phone has been untouched for about twenty minutes. The second I turn the screen on the problem alleviates itself. You can find even more information by googling that one, in fact both of those! The heat one I have not had, both with stock battery and zero lemon high capacity battery. The phone very rarely get's warm. However, when I was using wireless charging it would get warm even after charging was complete but I believe that is a normal event with QI type tech.
Unlocked my white 32GB after 300 MB download. No issues.
Installed a few apps, nothing special yet, no system related apps.
This afternoon my N9 started ticking from the bottom speaker each time I touch the glass. Just unlocking via pattern does it also.
About 12-15 very quick clicks like a speaker wire is shortening out.
Any hope before I call in a RMA?

How loud are these clicks?
It isn't unusual to get quiet clicks and buzzes when using a device, the Nexus 4 for example is a famous for it, it constantly makes a noise if you put your ear to it even when it is sleeping.
The CPU and other components are awake shy. They spend a large amount of time in sleep mode, perhaps coming on for a millilsecond then going off for several milliseconds, then back on at the next touch where it needs to display a nice graphic or do something, then off again. Everytime the CPU switches on, so does a lot of electrical circuitry to drive the power requirements. Currents switching on and off flowing through wires creates noise, either audible directly, like the hum from a kettle or a buzz from a power supply, or via electrical noise that is picked up by other circuits, for example the amplifier for the sound, which then makes it audible. Almost every electronic device if you put your ear to it makes a noise and buzzes, often changing in tone when you make it do something.
So I would say if it is very quiet, only audible in a quiet room when near to the tablet, it's is probably just normal operating noise. You might find a replacement is quieter, or you may find it is louder. You may find someone else can't hear it at all, if you are young you are more likely to hear these things than someone who is older as we lose high frequency hearing as we get older, and listening to loud music in headphones makes it happen quicker
Of course if it is pretty loud, audible all the time and annoying, certainly go for a replacement.
Regards
Phil
Just wanna make sure, but you are not talking about the button touch sound on Android 5.0 are you? The sound has been changed to a very swooshing sound that almost sounds like static on an audio line.
Thank you guys for your input.
The sounds I observed were loud, not the near silent hum kind. More like a finger nail is hitting a window.
The sound got progressively louder during my trouble shooting.
It ended up in a total distorted, muffled tone coming from the bottom speaker.
Something inside shortened out.
I had a micro-Tesla conductivity meter this morning at my bench and I could see that by touching the screen even at the top it induced a small current directly at the bottom speaker.
I called an RMA and the N9 was declared DOA.
Replacement is in the mail.

When you called what did you tell them? Where did you get it from? I got mine from best buy, and have this same problem. I think I'm going to wait until its closer to my 14 day period... Maybe I'll get a second batch device.

Not me. The ticking sound was the first thing I listened for when was testing out the speakers. I didn't hear anything out of the ordinary.
Took me awhile to be sure though cuz the song i used to test actually did have occasional ticks in it. I had to relisten to it on my headphones and on my home theather system to be sure it was just the song and it was.

I told them just my findings. Repeated click sounds by touching screen from a single speaker. This was a direct Google order and they sent a replacement within 24 h's. No questions asked.
The new White N9 is perfect. No unusual click sounds. In addition to that, there is a little less light bleed and from the few hours I used it so far I get the feeling that the battery is lasting a good bit longer. The first N9 went from 100% to about 40% within 3 h's of trouble shooting, the replacement is still at 75% after I unlocked & rooted and put back all my files, about 2.5 h#s screen-on-time. Makes sense, since the constant shortening out the speaker uses electricity.
The serial number difference of the last 4 numbers is a 44 higher count number, so I believe its the same batch/lot.
Overall, a quick and painless exchange and Google's RMA process is one of the fastest and easiest I have gone through.
Is anyone else getting a slight "crackle" when doing things with the device?
While my device isn't doing it all of the time, the speaker will occasionally randomly crackle/pop when playing a brief sound (such as the sound made while tapping app icons or adjusting the volume).
Doesn't seem to do it when there's an actual constant sound playing though, which is pretty odd =/
I heard a crackle/pop on a display model at bestbuy. I hope its not a problem on all of them.

I was beginning to wonder if I was the only one haha.
This sort of problem seems more indicative of a voltage issue than an actual speaker issue though at least, which means it could be fixed in an update if it is a widespread problem.
It reminds me of a problem I had with another device that was more or less fixed by either changing the governor or increasing minimum voltage.
Welp, my thread got moved here and this forum is pretty much a graveyard. If anybody else has this issue and happens to figure out how to fix it, please PM me, as I won't be bothering to check this thread.
As near as I can tell, it only ever happens while it's USB-attached to a PC (in my case, a Mac laptop).
Mine crackles for a few seconds every time I open the camera app. Didn't start out that way. Want to say it started about a couple weeks after I got the phone. Maybe after an update but not sure. Everything works so I've just ignored it.
Hi NeoRage. Am getting the same problem (crackling when opening the camera) - did the problem go away?
I have the issue too. S6 Edge I noticed it when editing my contacts, it cant be good that electricity is arcing someplace! but like someone else said, it keeps working so... I don't know if it coincided with Marshmallow but it was right in that same timeframe.
I purchased a refurbished Nexus 9 a year and a half ago. I've used ROMs to get it to 7.x and get all the regular updates OTA, currently on the May 5th security update. I've been playing CSR Racing 2 on it for about 9 months. The game has many known issues on Android of all versions and all devices, including crashing to "desktop". This problem is more unique. At almost any given moment in-game I can get a whited out or nearly opaque white, blocky screen overlaying the game image. At the same time, usually, an ear-piercing squeal kicks off. I have the volume at zero at all times, btw.
I've done everything except wipe the thing and re-install. Interestingly, I've had the problem outside the game once, although I can't recall what I was doing at the time. I'm inclined to believe it's the hardware. I actually ordered a Shield, and should be receiving it tomorrow, believing that it's the hardware. Once that is received and the game is up and running - unless I have the same problem on the Shield (meaning the problem's in the game or my profile itself) - I will be wiping the Nexus 9 and finding out once and for all if the thing's toast. In that vein, I have two questions.
One, is there some type of diagnostic I could run to check the limits of this tablet? CSR2 is very taxing on hardware, especially Android, and pushes it very hard. I'm wondering if there's a diagnostic that is a stress tester of sorts that I could use to see if there is any specific problem with the hardware.
Secondly, is there a ROM folks think may have better hardware interfacing for the memory, CPU/GPU, than stock Android? Obviously, I'd like the diagnostic to test the hardware while the new tablet will test whether it's the game/profile. What I won't have tested is the Android OS itself. Any recommendations?
Thanks for your time and any help that you may be able to offer!

Hi, Kazz5...
I can't comment on CSR Racing 2, having never played it myself, however the crash symptoms you describe - a largely white, blocky, garbled pixelated screen accompanied with a loud, high pitched banshee like squealing or shrieking noise (it scared the crap out of me the first time it happened ) is certainly something I've experienced myself several times on my Nexus 9.
I've had this spectacular and very noisy crash happen whilst playing Minecraft and whilst playing old (1990s) pinball games via video game emulator apps. But it's also happened when doing something no more taxing on the hardware than checking my emails with Inbox or browsing the web using Chrome.
There doesn't seem to be any logically consistent reason why it happens or under what circumstances are required in order for it to happen. It just happens, suddenly and unexpectedly, and then I find myself hurriedly scrambling around for the power button and long pressing it in order to make the ear piercing howl go away!
I've noticed when it happens my battery is on the low side, usually less than 25%, although I'm uncertain whether this is the actual cause.
----------------------------------
A Possible Solution...
Recently I flashed the Fire-Ice kernel , primarily for the purpose of improving the thin, weedy audio that Andoid Nougat 7.1.1 suffers from on the Nexus 9. (See my post here.)
Now it could just be a complete coincidence or maybe the unique circumstances required to trigger this crash haven't yet arisen on my Nexus 9 since I flashed it - in other words, perhaps I haven't been running it long enough yet, but since flashing Fire-Ice eight days ago, I've had no recurrence of this hard and spectacular crash as you and I have described.
Flashing this kernal though, will cause complications (but not insurmountable ones) when the June OTA security patch is due from Google in around three weeks or so.
----------------------------------
Sorry I couldn't provide a more definitive solution to this problem... or suggest any diagnostics of the type you allude to or suggest solutions regarding CSR Racing 2. If this game is as cutting edge as you suggest, it may be asking more than the now two and half year old Nexus 9 can deliver.
Minecraft, old pinball games and Solitaire card games are about as high octane as it gets for me these days .
Good luck with your Shield and I hope you have a better experience playing CSR Racing 2 on it than on the Nexus 9, and which I suspect you probably will. The Nexus 9 has been riven with a variety of problems ever since it was released back in November 2014, and this seemingly random, complete crashing of the device is unfortunately one of 'em .
Rgrds,
Ged.
I read this reply via email before taking the time to come here and I just want to say thanks for such a thorough sharing of your experience and perspective! You made it clear to me that ordering a Shield was the right thing to do in my case. Interestingly, my Nexus 9 did the squeal/crash in another app soon after I posted this.
My Shield came in, upgraded painlessly, OTA, to 7.0.0 and seems to run much smoother than the Nexus 9 in every way. Yes, the screen is a bit smaller. But, frankly, I'm seeing less pixelation - I have to assume - due to the smaller screen size. The Shield runs cooler (I used to blow on the hot end of the Nexus 9 when holding it in my hands, in it's case, for longer periods of time) and the battery definitely lasts longer.
I will finish moving everything over to the Shield in the coming few days and make up my mind what I want to do with the Nexus 9. With it's large size and 4:3 aspect ratio, I may relegate it to electronic magazine reading - of which I have a few. I saw a reference to running some flavor of *nix on it. That could be interesting. A touch panel for security cameras is a thought, if do-able, as well. I'm sure more thoughts will come up, including getting a more stable Android installed on it.
Please keep me/us posted on your experiences with the Fire-Ice kernel! And thank you again!

Now it could just be a complete coincidence or maybe the unique circumstances required to trigger this crash haven't yet arisen on my Nexus 9 since I flashed it - in other words, perhaps I haven't been running it long enough yet, but since flashing Fire-Ice eight days ago, I've had no recurrence of this hard and spectacular crash as you and I have described.
Flashing this kernal though, will cause complications (but not insurmountable ones) when the June OTA security patch is due from Google in around three weeks or so.
----------------------------------
Sorry I couldn't provide a more definitive solution to this problem... or suggest any diagnostics of the type you allude to or suggest solutions regarding CSR Racing 2. If this game is as cutting edge as you suggest, it may be asking more than the now two and half year old Nexus 9 can deliver.
Minecraft, old pinball games and Solitaire card games are about as high octane as it gets for me these days .
Good luck with your Shield and I hope you have a better experience playing CSR Racing 2 on it than on the Nexus 9, and which I suspect you probably will. The Nexus 9 has been riven with a variety of problems ever since it was released back in November 2014, and this seemingly random, complete crashing of the device is unfortunately one of 'em .
Rgrds,
Ged.

I wanted to follow-up with you on an experience. I moved to the Shield K1 and have been using it since May. Something's happened with it's charging (I suspect the mini-USB port's connection as it seems to be a weak spot for many). In a pinch, to keep playing my game of choice, I picked up my Nexus 9 and gave it a full charge. I was thrilled since it was working so well. But once it hit 58% charge the weird screen and shrill shrieking returned. Now cornered, I did my best google-fu and uncovered a couple of threads that claimed I could fix my Nexus 9!
It seems many people were having success with removing the back panel (easy), gently prying a small, metal cover off of the battery's connection at the circuit board, unplugging the cable, cleaning connections with isopropyl alcohol, and re-assembling. I found a Youtube link (ifixit, I think?) there that showed how to disassemble the Nexus 9 and I was off! It seems some folks have had this clear up the problem for months and some have had it recur, fixing it again with the same procedure.
I've been using it for days in all states of charge with no return of the problem so far. It's given me plenty of time to get my warranty-replacement Shield enroute. The Shield is still much quicker. But I'm thrilled that there's not some odd gremlin with the Nexus 9. I knew I needed to track this post and your reply down in order to let you know. I hope it helps you and/or someone else!
And thanks again!
Just wanted to bump this thread as I am having the same problem with my N9 and it is steadily getting worse. When this problem first started, it would happen once every 2-3 weeks, usually when I was in Instagram. Now it is happening daily, or multiple times in a day, and sometimes it occurs right after reboot.
I have gotten frustrated enough that I am going to do a clean (reflash) of Pure Nexus, ElemX, etc and see if that has any effect.
Did you read my reply? Cleaning the connector to the battery has fixed my issues - which were constant - for weeks now!
I just got one of these Nexus 9 32GB giving to me by a family member as they upgraded to something else due to the issues with the Nexus 9 . It had the whole deal going on with the white pixelated screen freezing followed by a loud ear busting screeching noise at roughly 50% and 20% battery. I factory reset the tablet and cleaned the cache in recovery then popped back off the tablet and disconnected battery for a min or two, hooked it back up and it runs like butter so far for the last week through the whole cycle of the battery without freezing or screeching. Strange indeed but that fix works for whatever reason.
