To all people who have this problem! I recently got the Nexus 7 3G and the back was creaking so badly you could easily hear it across a large room. The noise seemed to come from the "nexus" logo near the top of the device.
I found the culprit an double checked with an older 16GB model. They changed the design of golden contact springs for the wireless radios from a simple C shape design to some complicated folding Z shaped spring design. It is those springs that upon being depressed rub metal on metal and make this horrible creaking noise. I don't know how many 3G's are affected but mine definitely was.
My solution was to open it up, which is easy enough to do with a guitar pick or something similar, just check YouTube, and to bend the springs until they stopped making noises under load.
While I was in there I also added double sided tape wherever necessary to stop the plastic from creaking (because they left out a lot of the foam they put in the older models, maybe to fix the screen lift issue??) and I re-wrapped the battery protection circuit because the circuit board was rubbing on the battery and making noises as well. (also, my battery was strangely wedged sideways in it's compartment)
All in all it's rock solid now, no creaks, nothing. And it feels like a really quality device now. Suffice to say that I should never have had to do this in the first place in order to own a device that is in satisfactory condition and one is not embarrassed to pass along in a group of friends because of the noises it makes

Would u mind taking a picture of the inside where u added tape to stop the backplate from creaking and upload it. I've tried many things to fix it to no avail.

i will as soon as i find some time. there is another thread here on xda. it's for the wifi model but i adapted the suggestions for my nexus 7. also, what i did for mine might not work for yours. my suggestion is, figure out where the noise is coming from, add some double sided tape or foam close it partially and try it. took me about 2 days of trial and error to achieve an acceptable state

Thanks very much. My only creak is on the right side where the battery is and close to the bezel. Did u happen to have one there as well? Wish me luck lol off to void my warranty

Bookmarking so I recognize your nick on an upcoming "My wifi doesn't work!" thread.
Don't worry about your warranty! there is a "seal" sticker INSIDE the case but popping the back off will most certainly not void your warranty. it's more like the battery cover on a galaxy s3 or a nexus s than anything else!
fyi i had it on the right, left, and top of the device
Hello world!
I like the fact that this device will be "waterproof", but a question that's popped up in my head recently is whether or not that applies when using wired headphones too. For example, say you're standing in the middle of the monsoon rains listening to music. Will the headphone "socket" be isolated well enough that the use of headphones is rendered safe & sound, or will we have to use Bluetooth for that purpose?
Hope I get my point across, as I don't really know how to ask this in a decent fashion. :victory:

Good question! But I don't know the answer maybe mail Sony

Unless the bundled headphones are water proof, I wouldn't do that. I think the headphone jack should go so easily, the headphone itself will be ruined.
Once I was washing hands while I was listening to music, and I touched the cable and it went right on the running water. The right ear stopped working. Luckily I was at home and used the hair dryer on the headphone. It isn't still that good (left ear is louder and play more frequencies), but it have to last until I get new headphones.

No, opening the port flap to the headphone jack invalidates the water resistance. As it's been said before, your headphones probably wouldn't survive much water either.

Xperia Z may be a advertised water resistant phone but when any of it's port covers are open it's the most prone to stationary water.
If you plug in your headphones indoors than it'll be ok , just don't do this under the rain

it is risky
i think it will not be "waterproof" any more,
it will be at most "water resistant"
sony xperia z handset's various ports, including the one for its headphones, all feature protective plastic covers that must be unclipped before they can be accessed. - so dont even try ur phone with headset in rain, rather attending a calls and reading messages with ports closed.
source: http://www.dailymail.co.uk/sciencet...-CES-2013-The-phone-use-bath-drop-toilet.html
So, the general guess is that it:
loses its waterproofness if I plug in the headphones mid-rain?
...and...
is water-resistant as long as I plug in the headphones when it's not raining?*
* Read: meaning that it won't take damage from getting a drop or two onto the output jack when something is connected
Mail sony and who knows you might even get an interesting reply from them - and can share it to earn brief fame among tech blogs
But u still can buy Sony's waterproof headphones, which cost £60 and go on sale next month
And take a shower safely while listening some music

i think you guys are confused about waterproof and water resistance.
heres an article http://boyslife.org/outdoors/askgearguy/9135/waterproof-or-water-resistant/
mainly the xperia z is not a gadget where you could operate under water. thats why there are videos out there of xperia z when you pour water on it the screen starts to act up as if someone is pressing the buttons.
taking a phone to operate under water is a whole new level. there is a reason why sony states 1meter under water for maximum 30 mins. IP57 certified - dust and water resistant. technically speaking, its something for like when you accidentally dropped your phone into a bucket of water and quickly pick it up or talk under the rain should be fine since the screen is off when youre in a phone call.
A lot of ‘waterproof’ electronics are IPX7, which means that they will be OK if you accidentally drop them in a stream and get them out immediately.

if the 35mm jack hole is water proof then theres no point for sony to design a cover on top of it.
haha would it work if sound was coming out of the speakers instead? haha...

Any specific reason for it doing so? I've read that it has something to do with it being capacitive, but not completely sure what that actually means in this context.

This is generally the case with all capacitive touchscreens.
Capacitive touch screens work by using a thin grid of conductive materials on the screen to sense touches from conductive materials, like your finger. Water, obviously being highly conductive, messes it up quite badly.
This is why you generally can't use any capacitive touchscreen when it's wet; even a drop will usually make the screen freak out and sense touches that aren't being made.
I heard that the XZ has some tech that helps it sense fingers over drops of water (ie, just taken out of water), but it's probably not smart enough to handle being completely submerged. That would be my guess.

Probably, yes, as you'd have to prove the you had put on all the lids and things like that.
why there's no one think this way!!
get a bluetooth waterproof headset and you can listening your music under the rain (even without using umbrella)..
I ordered a vinyl sample for my car and I guess I got the crazy idea of using it on my Chromecast and this is how it came out..
check out the video to see how it came out! (youtube) watch?v=tEIbwPRZ-Qk

I'd be concerned about how much this insulates the unit, and how long it will stick, it gets pretty hot.

I dont know yet I just stuck it a while ago. I'll report back in a few days to see if it stays on... I actally never thought of that..
Hehe, looks cool. I wouldn't be too worried about the side edges where you have the vinyl in the picture at least as that part is plastic anyway. The "faces" of the case, are sometimes else and designed to radiate heat, so I'd be careful covering them.
I'm afraid you might live to regret that decision! LOL
As soon as that unit cooks and the glue starts melting the covering will eventually come off and all you will be left with is a sticky tacky CCast! LOL

Its actually holding on pretty good I've used it for quite a while
I saw a few guys complaining about the scratched/bumped bezel which looks ugly because the paint will reveal the metal underneath.
Well, I also damaged my watch by accidentally hitting it . Permanent markers are not a good solution because they do not last.
Apparently the bezel is made out of aluminium and only the watch body is made out of steel, that why, maybe, the bezel is less resistant.
Last evening though, an idea came to my mind, which I also applied on the watch. The result is promising .
Using some fine sandpaper (600) and some real paper after that, I completely removed the paint from the top of the bezel.
As a technique, I laid the sandpaper on a flat surface (table) and then I pressed the watch on it while rubbing it. After the paint was completely removed, I did the same operation but using a regular sheet of paper (to add a nice finish on the metal surface).
Please be careful: you have to press the watch against the sandpaper (laid on a flat, hard surface), not the other way around. In this way you leave no room for mistakes and the revealed metal will be uniform and nice, w/o weird edges.
This is the result.
That actually looks really nice! I'm Impressed with it . Just out of Curiosity what watchface is that also as it suits the watch really well.
That's a custom watch face for WatchMaker (built by me). You can download it from here.
I'm not sure I have the b... sorry guts for this kind of job
First Hardware Mod!
That looks great! I know it's just a matter of time before I will need to do this. I have sanded/polished like this before and may I warn everyone:
Make sure you keep the sandpaper flat. If it rolls up under the face it will scratch the screen.Better yet, only do this with a screen protector.
Really nice. You should offer your services for a fee, to do this for others afraid to do it themselves. Not that you'd offer any guarantees, but you have proof you know how to do it right .

Wow that's a great fix for this. Showed the scratches on my bezel to the lg team at ces and they were surprised and would follow up with me after the show. They said they hadn't come across this issue (which I find hard to believe). Like you mentioned OP the bezel is aluminum and the lower parts are steel and seem to be much more durable paint wise.
I'm hoping they might send me a new watch with some better paint but if not I'm definitely going to use this method!
it does look good, however once you do this there is no going back ........
if you want a better finish you may want to try crocus paper after you have removed the paint on the bezel, crocus paper is very fine and may give a smoother finish.
http://en.wikipedia.org/wiki/Crocus_cloth
Once you have bumped the outer bezel into an outer object, hard enough to expose the metal under the paint, the is no going back either. But at least, there is a way to move forward .

So very true.
I personally think that looks fantastic and a milliion times better than a scratched bezel. Mine hasn't recieved any scratches yet, but seeing your results, I'm no longer panicked about that happening.
Thank you for a great solution!
yes of course, I like the look of it too
How long have you had the watch since you did this? Is there any signs of corrosion on the exposed Aluminium?

I did the operation on January 2nd (when I posted on the forum ). One full week passed since then .. no signs on the metal surface whatsoever (expected, it's aluminum and this does not corrode).
Here is a photo from today.

I've had my watch for a little over a week and don't recall hitting it against anything but this morning noticed my bezel has a scratch longer than half an inch. Doing a Google search brought me here.
I was going to try your method today. I understand using the 600 grit sandpaper to remove the rest of the paint from the bezel but how does the regular paper help the finish? My uneducated guess would have been to try a finer grit sandpaper such as 1200 instead of the paper.
You can use whatever finer than 600 you have (even coarser but you may risk it going coarser that that).
Unfortunately, 600 was the finest I had in house at the moment that why I used id. After that though, the metal finish was matte, missing that fine polishing .... there is where the regular paper got into action. If you use a regular laser printer paper sheet, it will act as a very very fine sandpaper, enough to give that fine polishing on the pure metal (aluminium in this case - soft metal, no other reason.

Please tell us what did you do exactly to the watch, step by step. Thanks.
My request to any other people who want to adopt this method, please record a video of the process. Then upload it to youtube and share it with us. Thanks.
The entire process that I used is described in detail in the first post of this thread.
There is also the possibility to use a nail file (there are some guys who did that and the results are quite nice as well).
Guys,
This looks fantastic. Perhaps even better than stock. I've got a 1/4" scratch, so not quite ready to take the plunge...but certainly thinking about it.
-Doc
I should probably post this here also. I managed to ding up my watch pretty badly crashing my skateboard, and a user suggested I try this method. I did it a little differently by finishing with a 3000 grit and using metal polish cream on the exposed metal to give it a nice shine. Here are before and after pictures.
The metal polish is definitely adding a nice touch. Thanks for the info.

So I got my new Z3C and was thinking: what if we can make flaps and audio port more waterproof?
Doing pressure sensor test I get reading around 1000 and it's increasing by about 30-40 when I press against screen with closed flaps. But it normalizes after 1-2 seconds and goes back to initial reading meaning tiny amount of air escapes. Does it mean my phone is not totally waterproof? Don't know.
Since this phone is just fresh-water proof (meaning no using in pool or sea) and I really want to use it worry-free in all kind of water that I dare to go in myself I really want to improve waterproofness.
I'm not worried about front and back since glass should be all.kind-of-things-proof. This leaves sd card and sim card covers, audio jack, mic holes and speakers.
So what I thought of was to "grease" flaps' rubber o-rings with rubber compatible oil/grease to make better contact with phone body or use some kind of silicone spread around rubber contact area before closing flaps to have semi-permanent seal and be still able to open and scrub extra stuff off without doing much damage.
For audio jack I thought to make some kind of plug - like pressy button but with a bit bigger "head" that has soft sticky rubber underneath so when pressed in it makes a seal with the edge of audio jack or even plug that is covered with silicone all the way.
Speakers and mic holes could be protected with bits of strong adhesive tape - it's easy to get sticky stuff off the glass and it'll be possible to hear some sound even with speakers covered. Not sure about mic holes because side plastic has matte finish but some strong adhesive should still stick?
So the question - has anyone tried something remotely related? Is it thinkable? Have I missed anything important? What materials (grease, silicone) should I use?
If anyone has done something similar? Probably... But no one ever posted about it on this forum. You can use the phone in the sea and swimming pool, as long as you rinse the phone afterwards. As for modifying the phone, I wouldn't do it. It might cause you to lose your warranty.
In terms of waterproofing the phone even more, I'd look at waterproof cases made for other phones with almost similar dimensions and see if you can do something about the case instead.

It's hardly modifying, adhesive sticker on glass is easily removed and thin film of silicone should be also easily removable.

That's the option. But I haven't seen any slim waterproof case that could be comfortably used all the time.
Anyway, curiosity is strong and I'll most likely try different options.
PS. can someone test pressure sensor - is reading staying high when screen is pressed or it fades back to normal with all covers closed?
I've just used mine in pool all weekends since I bought it without any issue and even without afraid of doing that! The same with my wife's Z1!
And I'm contantly opening/closing its usb port due my xposed modules development (debugging purposes)! Maybe some unlucky day I will screw it... who knows!
Ofc we always need to be sure all ports are properly closed before going to have fun!

Sorry, I forgot about the pressure sensor part, it's normal that the numbers go back to normal after you lifted your finger, it works like that for everyone.
If my mind serves me right, I've seen Sony ads with the Z3C being thrown in a pool or something similar, so a pool really shouldn't be a problem. And yes of course people will have to fight for their cause at Sony, they won't just put any phone under warranty, else people would exploit that.

I probably expressed myself bit vaguely. Thing is that pressure reading on my phone returns back to normal WHILE HOLDING screen under pressure. Initially pressing screen creates greater pressure inside the phone, reading rises but air escapes quite quickly (1-2seconds) and pressure reading normalises. After releasing finger screen pressure sensor shows lower readings for a second until extra air seeps inside to equalise pressure again.
Hope it's clear enough.
Also, does it mean that I got less waterproof phone that it should be?
I dunno about you but i've been using my camera in the pool for a while now and even for hours at times
