Since is a waterproof phone u can use a drop of water and try to clean using a small brush ( not a harden one) then use a bit more of water to finish. but don't push too hard to avoid damage the speaker. Do not use air compressed or vacuum, that will harm the speaker.

[Q] Seidio Case Question

Just bought one for the IncS & now looking at some other cases I notice they have extra holes for the ones on the phone while the Seidio cases doesn't. Does anyone know if these holes serve some purpose that they should not be covered?

I never even notice those wholes. I have a case that covers them and I never really had a problem. Although I find that if I have a week wifi signal and I take of the case it improuves a little bit.... but that might be in my head heheheh
remove the back cover, you can just see these holes correspond to the gps, radio module,
I guess these holes should be improved for the signal role of some..

[Q] touch layer of the screen

Hi guys,
can you explain why is the "conductive layer" clearly visible on the Z1 screen ( as relly dense lines at different angles) under some types of light (I've noticed it while sitting in the restaurant under littlehalogen lights)? I've switched from SGS II and there I can't see any lines or dots ( dots were visible in ZTE Blade that I owned before ).
Here's a graphical aid for your senses, it's form iPhone, but I thinks it's more or less the same.

The Z1 comes with a factory "screen protector" and that's probably what you're seeing and not the conductive layer

Back cover with logo.

Hey guy, I wonder if any of you know the name of the back that is not the phone cover, which is attached on the camera and flash.
Also if any of you know where to get one because by being the curious off a bit and a bit output.
I leave a picture if I did not explain well.
Sorry for my bad English, google translate. :silly:

PS: Also sorry if this question should not be posting here, I was not sure if it's here or somewhere else.
Do you want to replace that camera strip thingy?? I don't tink that's possible
That's called the camera's accent, or at least what Motorola calls it. As far as replacing the accent goes, that would be very difficult and most likely ruin the phone's water resistance.

What is this dark rectangle on back of Q6?

I picked up a Q6 finding the back plastic cover has this rectangular cutout. You can't see it in the photo, as I need to catch the light at the correct angle to see it, but the phone has a darker rectanglular area to match. It seems to be more under/in the plastic than on top of it. I haven't opened it up yet to see.
My initial guess is that it was an area marked out to mount something but, I don't know, that just seems like going to too much trouble?
Does anyone know what this is?

That's where the IMEI/barcode label is located on the back of the phone.

What are these little speakers called?

Trying to find some surplus ones for use in small laptops. These are Motorola phones.

I thought the image went in the first post but this is a valid link to it on Imgur.
I think the metal bar is the speaker cone and it's mounted on something rubber/plastic that flexes. There could be a voice coil type thing in there or it could be piezo- electric like those annoying little beepers.
Those look like blocked. Are you sure are not fake?
I don't think so. Most cell phones seem to have them, some have tiny holes in them.
I suppose I could try a stethoscope on them, or make something like it with a microphone and headphones. By a weird fluke I have a real medical stethoscope in the other room. Mechanics use them too.
