Camera Switching Sound - Faulty hardware? - Xiaomi Mi A1 Questions & Answers

Hello guys!
Today I've been going home and suddenly a really have rain started and a lil drop of water got on my phone and it went straight for my earpiece's mesh. I instantly wiped it away and I freaked out that something bad will happen to my phone.
Anyways, I turned it off and then tried to dry it with my hairdryer and started sucking on the mesh (desperate times) but the earpiece seemed to work so I shrugged it off.
FUN PART: I was in my room alone and everything was completely silent and I had the idea that I should check if stuff works so I tried the everything, then I got to the camera and I tried switching the cameras and I heard the NOISE. It's kind of a "tz" or "dz" mechanicalish (?) noise when switching the cameras, ESPECIALLY if I switch it to the front. I asked one of my friends who also has a Mi A1 and he said that his phone does the same.
Can you try it too? It's audible only in silence, or if you put your phone to your ear and switch cameras that way.
Thanks in advance!

Mine too, it's normal, just the camera focusing in I think.

Thanks for the quick answer. I was hoping that other people experience this phenomenon, and my phone isn't faulty after all. The only thing left is that my fingerprint sensor looks weary.. But I gotta live with that I guess

I'm waiting for other people's replies also!

Omg yah haha. I have that tz tz sound as well! ?

I have it too

I remember having it on other phones as well. Shouldn’t be a problem

yes mate i have that to..its not a big deal...

Thank you very much for the replies!

The phone camera contains moving parts which is used for focusing.
When you start or close the camera and when you focus, you can hear a sound coming from it.
This is normal. It is not related to the software version in your phone nor the phone model.
I suggest you move on, nothing to worry about!

[Q]TD2/Pure Owners: Vibration Rattling?

Hey everybody,
I purchased a Pure last Sunday, and have noticed that the vibration doesnt feel as "solid" as i'd like it to.
A big pet peeve of mine was that my fuze made a lot of noise when it vibrated because the two halves (if you want to call them that) (screen and keyboad) buzzed against each other. I was really hoping to have a feel on the pure similar to the iPhone where its an inaudible vibration (the way it should be).
My Pure vibrates and it sounds like something is rattling around inside, not like its physically shaking the device. Anyone have any similar comments or different experience? I'd like to go swap my pure out with AT&T if it means I'll get a quieter vibrate... Thanks!

If the sound comes by the camera that is normal. Like if you move or tap the back of the phone. Its the auto focus.
I it's not that then IDK. All I know is that the phone doesn't vibrate enough form me and I've never had noise problems. Not even from the camera when vibrating.
I use this (Touch Response) It works great and gives for better tactile feedback. You can set the intensity by making it vibrate shorter or longer. My prefered settings are in the first post I made. (The First Post LOL)
yeah, i used touch response for my Fuze. its hard to tell where my rattling is coming from, maybe i'll swing by the store and get a demo unit to buzz...
I have a weird rattle as well, if i tap the back of the top of the unit it makes a rattle sound. Sometimes when it vibrates the sound is odd too so i assumed that the rattle was that. Is that what ur rattle is like?
I took it to carphonewarehouse and they were like send it off to HTC to get it fixed, would take 2 weeks so i was like hmm its working fine atm so dont worry.

That rattle your getting is the auto focus camer. It is normal. Use the camera and you can here it move and fixate when you take a pic. It's like that when not in use.

Rattle from phone (not volume key)

I know there is another short post about this, but wanted to get a quick poll from people about whether this is even a fault. The phone does not appear to be malfunctioning.
I have noticed a rattle in the head of the device (this is not related to the volume button, mine is a bit loose, but it doesn't really bother me). If I shake it perpendicular to the screen, it makes a small rattling sound. If however, I tap it lightly near the back speaker, it makes a large and rather unnerving rattling sound (if you're going to test for this, please hold onto the volume button to rule this out). The issue with this is that when I take a call and the volume is quite high, whatever is loose appears to rattle sometimes, making the unrelated but highly annoying audio distortion problem even worse!
I have managed to get opinions from 2 other users already. One has it, the other doesn't. That makes 2 that have it and 1 that doesn't so far.
Any ideas on what it might be, also appreciated!
Mine does it, i suppose it could be the camera lense =/
I notice the rattle, and have noticed previously a nasty distortion type rattling sound when on a call.....
Mine phone started doing that after using the camera edge to open beer bottles. But only after the 12th bottle....
mine too...
My phone does it too, when i shake the phone it doesnt sound but when i tap the speaker it makes the loose kinda screw soundm it almost sounds like when the lens is focusing it makes a sort of click its almost the same so i would assume it is the lens, after all my phone is working great, only the screen fails to respond sometimes when typing an sms or using the sense keyboard...
i think it is the lens
it is the lens, is has a small magnetic mechanism, similar to a solenoid to move the lens in and out for focusing. If it didnt have a little rattle, your autofocuser is stuck
OK thanks for the replies, looks like pretty much everyone has got it, but curiously, I got a reply from HTC on the matter, concluding that there might be an issue with the handset. Admittedly I asked about the sound distortion too, but they recommended a replacement?!? Sounds like they don't know about this or just blanket recommend a replacement if they're not sure.
I'll probably stick with the unit though, other than those 2 issues, my handset is perfect.
Thanks again for all the responses!
Hmmm I just rang htc about this has mine as developed the fault.. Also reported that my bottom buttons are starting to peel. Not to sure if i should send it off now or not.. Problem is.. It didn't do it before so why is it now? The guy on the phone was hinting towards me maybe dropping the phone I think and said I may incur a charge if they don't believe it is a problem with the phone.. Which I no I shouldn't but find really offending because I treat my phones like a baby and has never been placed on a surface hard in its life (and always placed on top of the htc case) let alone dropped.. But I know there are a lot of people who don't mind spending £500 on a phone and not treating it to well so I guess they have to presume this..
Anyway..
I also think it is coming from the camera area.. I never use the vibrate function so turned that on for a bit to see if that would make any difference and also used the camera for a while to see if it was the auto focus but still the same. If the noise wasn't so obvious I wouldn't send it in for repair but I think this noise is going to do my head in.. (also want the buttons replaces as they are starting to peel)
If they try to put the noise down to misuse I think I will be selling up and moving back to apple.. Shame because I love the HD2.
Just out of interest my phone came from one of the 1st batches from Clove in November.

Microphone issue N1

I have had my nexus for about a month now and a little while back started having problems with the microphone. People on the other end will say I sound like I am in a "tunnel" or "distant". Seems to get worse during long conversations. Sometimes I can hold a 20 minute conversation and not have one problem other times it gets so bad that they cant even hear me.
I have really good reception and 3g at my house. I called T-mobile to see if it could be something with their network and they said probably not since they had only noticed problems in Texas and some other random state (I live in BK,NY) . Called HTC and they were no help at all (said I should try and reboot my phone thats all they could think of). Called google and they said I sounded just fine. As I said before It doesn't happen during every single call, but I have had about 3 different people tell me the same thing...
Anyways, the bootloader is unlocked so I can't send it in to get it replaced or even have it looked at with out paying an arm and a leg.
Anyone Have any ideas? Anyone? Bueler? Bueler?
Thanks.
Ok this is just a random thought as I have had a similar experience, but only when I hold said phone with my shoulder. Are we perhaps doing something to the noise cancelling mic? Would covering it make a difference during a conversation? Something to do with the proximity sensor? i am just thinking out loud.
I dont think its the proximity sensor because I put tape on it keeping the screen off and it was still doing it. as for covering the mic on the other side I don't know. I guess i could cover it for a while and see what happens. I'm going to send it to HTC and see what they say. Hopefully its a hardware issue that they can fix for nothing.

Issue with vibration

Hi,
Just got my Desire HD today and it's all good except I've noticed a rattle when the vibrator kicks in, ie when you're entering text for a message etc that is a very different sound to the actual vibrator itself. Has anyone else noticed it?

Dude! have the exact same Issue! I was going insane, because i thought it happened after i dropped my phone. But You're saying you have it and your phone is new. Anyone else?
My vibration motor failed last Friday. Makes a scraping/clicking/whining noise depending on how I hold it. Never dropped and kept in a HTC leather pouch all the time.
HTC UK quoted 28+ days to repair as "there is a backlog of repairs, due to us moving repair centres". Told them to fcuk right off, not waiting that length of time.
Twisted Phones4U's arm (who I bought the handset off) and they reluctantly agreed a replacement.
I'm still waiting for that, as the first replacement had extremely poor fitting covers, both battery & SIM/SD card.
Sorry to hear that andy. But the issue we are describing is the vibrator producing a rattling "click" sporadically when delivering haptic feedback. It's close in sound to an ipod keypress osund (LOL, didn't know how to describe it otherwise). It's a minor issue, but it's driving me insane! We want to see how many people have noticed it, and if there is a solution/workaround
Same issue here - worked fine for the first week of owning the phone and since then the vibrate function rattles so loud it's embarassing so I avoid using it altogether (not to mention it's a horrible high pitched sort of sound).
I have, however, noticed that if I gently squeeze the left and right sides of the phone and test the vibrate function it works correctly as it's meant to (I try to avoid doing this often as I'm scared I'll damage the screen by putting too much pressure on it). It's almost as if the vibrate motor gains some breathing room and space for movement.
This leads me to believe that either the various removable covers are no longer a decent fit (and they were a pretty bad fit to begin with) and are causing the rattle or the whole case has warped somehow causing the vibrate feature to play up.
I'd be interested to see if any other people confirm this to be an issue.
I have baught my Desire HD around 6 months back. Even my phone gives rattle sound (Something like there are some loose part inside). I don't remember if I have this issue when I bausght the phone, But I am facing this since long time.
In some threads they say the metal ring around the camera could be loose and it rattles when the phone vibrates. Maybe it could be that but my phone vibration is weak but normal.
there comes more and more a louder sound when the phone is vibrating. but when its in my bag, its sometimes better i hear it a bit

Rattling / vibrating earpiece

Has anyone else noticed the earpiece speaker rattles/vibrates during calls on their Note 4? Its not terrible, but its defo noticable and really annoying. I expected a perfect new phone. Was wondering if this is a general issue before I swap handset?
I havent noticed but could it be the camera module, hold phone close to ear and shake gently, same noise?
I'd say go for a replacement, mine does not make any obscure noise, my 1st note 3 however had an obnoxious vibration from the speaker.
Looks like I will have to go for a replacement I think. Theres no sound coming from camera. Thanks for the suggestion though. I even tried taking the back off the phone to see if it was that vibrating slightly, but no different. Tried pressing against top part of pbone too as thought this may firm up any loose parts, but had no joy. Its a pain as just set all settings as I wanted and really wanted to avoid replacement. Oh well lol. Thank you for your reply, appreciated!
Finally managed to change phone after store got new stock in. Turns out I had a faulty handset. New one is perfect, no unwanted sound from earpiece at all!
