[Q] USB rubber cover firm enough?

Hi all,
I've recently bought a DEFY. It works quite brilliantly and very fast.
I've noticed that the USB rubber cover of my DEFY is not very firm when closed. There is a little seam between it and the phone body, and the seam grows a bit thicker as it approaches the USB port side. I've included some pics of it.
Higher res pics are at

ishuo.de/images/defy2.jpeg
ishuo.de/images/defy3.jpeg
(Sorry I don't have enough permission to directly link pics here.)
I've also spilled some water onto it under a water tap. When I opened it I could see some water drops on the edge of the inner side of the rubber closer to the back.
I don't know whether this is normal or defect and I'm not sure whether it will stay up against water which is one of its great and practical feature.
Can anyone compare it with yours? Are all DEFYs like this?
Thank loads and happy holidays!
Cheers,
Shuo

When I close mine I am careful to press it in firmly as otherwise it looks "not quite shut." It has to squeeze in there. I presume this what's suppose to keep water out and as I have dunked my phone countless times without incident. However, if you think yours is twisted or bulging when seated, I don't think that's right.

Mine doesn't have that small hump when in place. I think there is some extra rubber under the clip.

yeah mines got that, you get the bump when the cover gets bent the other way when you move it to get the usb cable in

After charging mine looks like it will stay with the bulge like that when I put the cover back in place, but even so, I can press it firmly, and it actually snaps into place. Sort of even has a clicking sound. I only started noticing this as before I would press it in even, and the bulge would stay there for a while and slowly smooth itself out, but now if I press it in, and then press my thumb/finger all the way around the cover, it snaps into place very tightly.
EDIT - After looking closely at mine I see the hole is actually at an angle, so pressing it in straight would leave it with the bulge. You need to press it against the angle of the phone for it to snap into place.

exactly what i was about to say - works for me.

Wow you are so friendly guys.
Thanks lods! I'll look into it when I come back today!

I did get a slight feel of "snap in". Just dunked it shortly into water, and it still lives!
So I guess it's all right.

I get some moisture around the USB plug hole even when the cover is in place as well. Probably not a big deal. You can try using some grease to improve the seal as well.

One review notes a small amount of "O-ring" sealant or grease around the battery cover rim. I supposed you could add a little. Just don't use vasoline, that's a pertroleum product and will degrade certain types of real and synthetic rubber.

Possible to buy new covers?

I just got a Motorola Defy and I think the USB cover is a bit loose. Some say you need to apply a bit of force to remove and put it back on but I only have to touch it with my nail and it pops right off. This phone will definitely not work in humid areas with such a loose cover. And this cover has to be opened and closed on a daily basis, I don't trust it right now.
Why is it that no one has realized how insanely useful inductive charging would be on a rugged phone?! No stupid flaps/covers that can get worn out.

Mine is nearly 3 months old, and the usb cover has been opened/closed for over a hundred times. The cover is not as tight as before but defy is still very water resistant.
Actually I just wash it with tap water. I no longer throw it to water/beer for fun now, but I am very confident that it can survive an accidental drop to water (immediate pick up) or a little rain/water flash with the covers closed, even a bit loosely.

The USB port does more than just charging though. Even with inductive charging, you'd still need the USB port. True, you might not open it as much, but it would still have to be there.

[Q] Random touches with replaced digitizer

I replaced my digitizer on my inc and now it will randomly have touches on the screen. I have no idea why this is happening. I have tried two different digitizers with the same problem. It gets worse, i have tried the first digitizer i got on a second phone and this phone has the same problem.
I am running cyanogenmod and have "show touch" turned on so i can tell when its happening and where. The random touches appear to happen all on there own. I can not reproduce them. They do generally happen in about the same spot/spots each time. There are two general areas and when its registers a touch it moves a little, meaning when it touches it self it dances around a little. how ever if i turn off the screen and turn it back on it usually fixes the issue for a while.
Any idea what may be causing this problem and how to fix it?

Funny, I am having the same exact problem. Replaced my digitizer about a month ago and routinely get the "random touches" or just general unresponsiveness while using my phone.
I just assumed it was a side effect of my less then perfect installation but now I wonder if the digitizer itself is shoddy.

Have you considered the trackpad as the possible culprit? I know when my phone does similar things (swiping homescreens, moving the cursor when typing, etc) it's usually because the trackpad is dirty. I can't really think of why the digitizer (assuming it was properly replaced) would be causing that problem..

My buddy Bob had this happen to his Incredible too when he cracked his screen and had it replaced. He had it replaced 3x through Best Buy because each time it came back it would freak out like that. It turns out that something inside the phone was shorting out to the chassis, it would only happen when he squeezed/held the side of the phone. They ended up just giving him a new one after the third time.

Yeah im thinking it could be something shorting but no real way to test. But after many take apart's i seem to have got the screen to a point where it does it like all the time rendering the phone useless. i have put back on the original screen and am seeing if there are problems there. (i got a new plastic housing)

Yeah i have disconnected the track pad and tried that with no change. and i tried disconnecting the light bar for a try and it would not boot. but i only tried once and i could have messed something else up when i put it back together.
i will report back with how the stock screen does and i'm thinking that will confirm that its the replacement digitizers .

Well the stock digitizer is doing the same thing. So its someting on the board, but i have tried it on two different phones.
So im up for trying just about any suggestion at this point. I have 2 phone and 3 digitizes doing this.

Mine does the same thing. I replaced just the screen awhile back.
I thought it might be related to maybe an upgraded screen family and the kernel not supporting it or something..
Like this post:
http://forum.xda-developers.com/showpost.php?p=15132827&postcount=3626
I usually take off the back and then pull the battery and snap the case back on. Seems to fix the problem until I mess with the battery again.
Anyone know how to see what touchscreen version you have?

ok so i have 3 phones(boards) 3 digitizers. 2 phones are the same hardware version i believe, one isn't. and all three experience this problem. This is even with swapping around the digitizers. I'm thinking that somehow all of these share something similar. All i can think of is me putting them together.
Any idea on what they share?

Just wondering if you ever fixed the problem or got it figured out to some extent?
Same thing is happening on my phone ever since I replaced the screen/digitizer. Took it back apart and cleaned all the ribbon connections and the problem is still there. Thinking it might be a grounding issue possibly since it seems like it goes away (most the time) after I vigorously squeeze the bottom of the phone, by the trackpad and capacitive buttons. But it invariably comes back, and seems to be worse when plugged in to the charger for whatever reason.
Also, since you've also taken apart and reassembled your phone, have you had an issue with the trackpad not sitting flush with the screen? No matter how I reassemble everything, it seems like my trackpad is recessed now and it's even worse when I use the little rubber gasket that was on there originally...

I haven't been able to determine what the problem is, but mine seems exactly like yours. When charging I pretty much can't use my phone random touches everywhere, or it doesn't fully reconize my touch. I just took my INC all the way apart and cleaned everything connections and all. I read somewhere it could be a dirty optical pad so cleaned that good too. Just powered on *Fingers Crossed*

when you replaced it did you make sure you the ground straps where connected to the screw holes with nothing interfering? i pulled my LCD out of my screen on my dev phone because there was dust under the glass. after i put it all back together i was getting the same thing descried in the OP. so i took it apart and noticed that the thread lock used on the screws pealed off and on the ground straps. so i cleaned them up with Alcohol and a cotton swab. put it back together and haven't had it happen sense.

When you say ground straps, are you referring to the two tiny screws that are near the top of the actual screen (after you've taken of the red battery compartment thing and the board)? I remember there being these little metal mesh strips that were in those screw holes that I think I promptly lost after taking the screws out..

yes. after removing the board on the back of the LCD screen there are 2 straps on the top that ground the screen to the frame. the screws had blue thread lock on the bottom. sometimes it will come off when you remove them.
basically make the head of the screw is clean and the metal straps are clean to make a good enough ground.
EDIT:
if you lost the screws you can try to pick up an eye glass repair kit. the ones used for glasses. they have small phillip screws that might work. you can normally buy the kit at a $.99 store.

I was wondering what the screws were for since it didn't look like they were actually holding anything in.. I didn't lose the screws, just the grounding material, which were those metal mesh adhesive strips. Trying to think of what I may be able to replace that with, maybe just some aluminum foil or something? There has to be some better material, I'm just not thinking of it..

the straps fell off? (the straps are on the back and should be soldered to the drivers on the rear of the screen) i wouldn't recommend aluminum foil. try going to a store like radio shack or any do it your self electronic store and see if the can sell you some fine wire mesh.

Hm, I think we must be thinking of different things, cause these were just tiny little pieces of wires mesh that those screws held into place that were stuck to the metal on the back of the screen. Might have to open it up again and snap a picture or two to clarify if I can't find any other grounding issues, etc.

yea thats what im talking about. the 2 straps on top that are screwed in. they need to have a clean connection from the strap to the screw heads that it sits on after screwing them down.

Well I'll be damned, I think that was it! I "borrowed" a little bit of that wire mesh stuff from the back of the screen (it's holding down the screen's ribbon connector and covering other things) and put the screws back in holding little strips of the mesh down and stuck to the metal on the back of the screen. I haven't been using my phone much but the phantom touches and vibration haven't come back, crossing my fingers that it stays this way!
Thanks again synisterwolf, mashed your thanks button a bit
To the OP: I'd highly recommend making sure the screen is grounded properly with those two tiny screws towards the top of the screen.

Thanks for the info guys! Does anyone have a pic of this mesh stuff. I think my old screen had it, but the new screen does not..

[Q] Back cover creak.

Hello there!
I bought my xperia m 10 days ago, and i am pleased so far, except for one thing..
I noticed yesterday that the removable cover has started creaking, especially on the side with no buttons where the usb port is.
Has anyone else noticed that with their device? Is this something that inevitably happens after a while, or should i try to get it replaced because of a defect?

Yes, it started happening a few days after I bought or... If it happens to others too, I'll assume it's inevitable
This message was brought to you from my Sony Xperia M C1905 using Tapatalk.

Hmm I see..
Well I thought I'd ask because if it is something that is going to happen anyway, i will not bother taking it to the store.
They will have to send the phone to the service center and all that fuss just to replace the back cover, so it is not worth it.
If someone else can also confirm that this is the case with their phone I will be assured.

My phone also makes noises when pushed, most at top right and bottom left corners.

Well I take it there is nothing I can do about it then, so no point in returning it, I will have to live with it...
It is a shame though, because other than that the phone is outstanding in terms of value, I see no reason to spend any more that what I spent on this. It hits the sweet spot for me in the price/performance scale.

Has anyone found any solution to this problem?
I have tried putting little pieces of paper at the hotspots (bottom left and below the usb port in my case) but I had little success...
I am also curious to hear reports from others, maybe a silicon case can lessen the issue...

I have silicone case, it is the same. I am thinking about using thin layer of hotglue. It can be peeled of easily.

After some experimenting I found that putting a small piece of paper (3mm tall and about 3cm long) between the phone and the cover eliminated the major creaks that where in the lower-middle left side of my phone. I just folded a piece of printer paper in two and cut it to the above dimensions. If you try it make sure to put it in a way that does not block the small plastic clips that clip on the phone.

[Q] Quality control problems with the frame?

Recently i received my Xperia Z1C White. After some careful checking (that happens when you are a techy) i noticed that the frame bends slightly inwards at the back side. I made a small example of what i mean on a photo. The problem is. If you can press those parts of the frame inwards, what happens with the waterproof seal between that part of the frame and the plastic bezel on top of this? Is this the case with every Xperia Z1C or is this a rare problem?
I suspect this also is the reason why you can hear a sound while pressing the screen slightly.

Same on my phone, but only the charging port side, and my phone squeaks too.

Me too - i can also press the frame inward. Oh my god, i´m a bit confused now...lets hope everything is ok and water is no problem for that...
*EDIT* But i have to say that this also is an issue to find on my Z1 !

Had a bit of convex shape on the back, barely noticeable. Hairdryer and pressing did the trick.
And no, don't be too harsh to the phone.
Glue seems to be unequally applicated.
Made in China after all.

I don't know why, but it doesn't seems any problem with my white phone.

I wonder hwo wide spread or problematic this is. On a normal phone this wouldnt be a problem at all. But on a waterproof phone every error can be a problem.

Mine seems to have the same microscopic gap on the back around the docking port.
I dunked it in a bowl of water and let it sit for 5 minutes. Took it out, dried it off - no problems.

The back of mine flexes when pressed hard in the center, but there are no gaps at the edges (even when pressed)

Is this something they'd accept a warranty replacement for? Where do you go about requesting such?

I think no warranty on this, they will probably consider it normal.
The problem with high precision designed devices like this and iphones is, that if something is a bit off you notice it easier.
I do regret it a bit that i didnt exchange it within the 7 days that it is possible to exchange a product after buying it in holland. But if it is widespread, then the case of a phone without the flexing frame/misaligned frame would be very small.

For anyone worried about the waterproof nature of their device, the only thing I can say is - test it. If the product works as intended you're golden. If not, you're covered by warranty.
I'm avid photographer and diver and with all new waterproof equipment, the first thing I do is test their waterproofing by either dunking them in the tub or the sink full of water.
You've bought a device with a capability which you should be able to trust. No need to find out 1 year later when you drop it in the toilet that your device is faulty.

Same here, only a small gap around docking port that can be ever so slightly pressed in under higher-than-normal pressure, never noticed it in every day handling.

Mine keeps pulling hairs out of my beard!

I believe there's a sensor-like surface when you open up one of the flaps (the micro-USB one I think). It's a small white square and it turns red when in contact with water.
This is how the service centres know that you are complying to proper usage. So do be careful not to get the internals wet

That would make sense

I have exchanged mine, still a little flex around the charging port but the back is definitely more flush. No small gap and less cracking noise when pressing the back as well. Very content with the built quality of this phone now.
