Battery cover vibrates - Captivate Q&A, Help & Troubleshooting

Anyone else's battery cover slightly vibrate when you gently run your finger over it? Only happens when the AC usb charger is plugged into a wall outlet for me.
Thanks!

My, and my gf's Cappys definitely don't do that ._.

Every once in a while, when I have it on vibrate and I'm putting it back into my pocket, I get the vibration. It's odd, but on the iphone 3G and 3Gs, when it is set to vibrate and you press on the back by the sound switch, it'll vibrate, too.

Sounds like you have a short circuit... My laptop has a magnesium palm rest and if it's charging and you touch something metal and run your finger over it it feels like it's vibrating.

This isn't the internal gizmo vibrating it. It is more like a natural frequency. Think making a tune on a wine glass. Very low frequency though.

If its a short. That could explain why sometimes my battery runs down really fast.

It is a short or grounding issue. The vibration intensity changes if I put my bare feet on the carpet or not.
Taking off the cover, I found that the metal sim card slot is actually whats vibrating.

Battery charger fizzing

I've noticed over the past few days that when removing my charger from the socket that its making a fizzing noise is this something I should be worried about?

Lol just worried ill be woken by a house fire one evening didn't know if other people have the same issue, it fizzes for around 30 seconds after being unplugged and all the time when plugged in.

From what I've heard, a large percentage of the LG chargers do make this noise (including mine), and I guess the volume varies too.
It does mean that it's a cheap, crappy charger but if you're not seeing any side-effects (such as the phone shutting off while charging) then it shouldn't matter. However I would advise to switch it off or unplug when not using it.
Mine is fizzing as well. As a precaution I remove the charger from the wall socket whenever I'm not around for a prolonged period of time. For what its worth: my phone randomly freezes both when charging and when not.
Dont worry. It's pretty common for cheap SMPS's. What you hear is the power supply's switching frequency
Yeah I've had the auto shut offs to and was hoping that that was down to a software problem? Hopefully chargers are not to blame.

Why not? Easy to swap a charger (as opposed to the phone itself! )

Battery door creaking

So, after recently replacing my phone, I received one with a really noisy battery door. I mean the sliding mechanism to take off the back plate. I've tried to cope with it, but it makes my vibrate unusable due to a huge increase in noise. Also, barely squeezing the slider part makes it creak annoyingly.
Does anybody else have this issue? If so, do you know of any remedies? I'm starting to get really annoyed with this, as it makes my phone feel cheap and I can't stand not having vibrate on during classes.

What you can do is put some tape or glue a thin plastic on the inside of the cover to create pressure that should prevent it from moving. It will be on the inside thats way it doesnt look cheap and it will fix both problems. Let me know if it works

Gah! Can't believe I didn't think to try this. I put a couple of pieces of card stock under the door and its gone. Thanks!

Built quality

Anyone else notice by the volume rocker switch that the phone case itself around the switch is not sealed properly and its coming apart?
Mine is fine. You sure its not your battery cover? Sometimes it needs to be is snapped in all the way.

Guess its time to return this one......

Does anyone know how to fix the audio...

My captivate audio die it's not the ROM because I flash 5 different ones but the problem is the it comes and goes I have to give it a tap in the back so it could work... But it's more technical then a software issue...

I've read on here on more than one occasion, that the speaker on our phones can come loose, and removing the back cover and pushing firmly in on the speaker will re-seat it. Give it a shot! Hopefully this helps.

It's a consistent issue with cappy's. Looking at the back of the phone with the cover off, the screw on the right side of the speaker is frequently over-tightened during assembly by the manufacturer, thus causing the left side to lift and randomly break connection. If you press to re-seat it and continue to have problems, try backing the screw out about a 1/2 turn (counterclockwise) and try again . Just don't back it out too much or you have the same problem. Good luck!

Glad it worked for you. I use the music player a lot and cannot stand for the speaker to cycle on and off like that. Anyways, enjoy!

Haptic feedback

What is that dreadful rattle noise that seems to come with the haptic feedback of every HTC phone? Sometimes the feedback seems fine then the weird rattle comes back. Had this phone one day btw. Dropped it once though.
Sent from my HTCONE using xda app-developers app
Have had mine for a few days now and has only had one fall from a few inches off the ground so I know my issue isn't from damage.
The haptic feedback seems okay for the most part, but any other vibration is crazy loud/rattles. Even while holding in your hand and not just rattling on the desk or something. Seems to be a common problem.

Sounds like a QC issue. It should not be like that. Mine is silent when vibrating, unless on a table or something hard that resonates the sound.

Interesting. Yeah mine makes the sound only when sitting on a hard surface, or if my hand is in a certain spot on the phone. I hate that sound so much though.

I can say that the vibration sound is quite loud and annoying. And it is only when holding it certain ways. Straight up a s down it makes no noise. At a 45° angle it is quite loud as well as holding it flat.

It's the worst! It's like this with every HTC phone I've had. I just turn off all haptic on HTC phones because it annoys me so much.
Makes me second guess not going with the s4

The vibration issue makes me want to take this back and exchange it in store. The data issues and next to impossible streaming capability(have not yet been able to stream a YouTube video using mobile data) make me want to just take it in and exchange for the s4.
The over all build quality and believe it or not, the ui and software makes me want to keep the One.
Still have about 10 days left to make my decision.

I pretty much feel the same way. I have 12 days. If the build and UI wasn't so sexy I would have already.
As I'm typing the vibration is getting more ridiculous.

I just don't get why it will go away then come back randomly.
