Volume knob went wrong - MTCB Hardware Development

I have a KGL unit, and my volum knob wnt wrong. Volume down is OK, but Volume up is softening the volume 90% of the cases.
Anybody has idea how can i fix the knob, or order a replacement?
On aliexpress, I can't find any.
Thanks in advance

That is a common problem with cheap pots, I bet if you crank it really fast it will work 60% of the time. But that is proably not the fix you want to hear. If you post some pics I can proably find a pot that will work but may need some modification. I wuld need a pic of the shaft without the knob and a pic of the inside to see if it the asme one as in mine.

I kind of doubt that it is a potentiometer; it is more than likely a rotary encoder.
When the radio is off, can you rotate the volume knob forever in either direction?
Does it give tactile "click click click" feedback when you rotate it?
If YES to these questions, (either or both), probably it is a rotary encoder.

Replacing button decal?

Anyone have any info on this? My "ok" button and some of the other's decal are starting to chip off and it makes it a real pain to look at. I just want to know if i have any options on replacing these or am I doomed to keep looking at them like this till they eventually all come off.
Same Here...
I have the same problem! Let me know what you find out!! Thank!

ditto i have same issue
really hoping someone has an answer for this
I'm having the same problem. I actually just noticed it the other day. Its only on my End call button and my softkey on the same side. i'm pretty sure that its from taking it out of the holster and the little metal clip rubbing against it.
ah that makes sense. i knew it was coming from the holster but i couldnt understand why, would still love to know if we can replace em
LOL, wow i thought i was the only one. Ive never dropped my phone but my top right soft key and windows key is completely chipped off clear now....it looks kinda cool actually lol....
Chipping
I used to work at a T-Mo Tech Center. There were about 20 out of the couple hundred of us who owned the wing. I introduced every one to XDA and often took friends' Wings home to upgrade thier ROM's. Over half of them had chipped buttons (ie Softkeys, Start, and OK). I always thought those friends didn't take care of thier Wings...until it happened to mine, and I am overly careful with it. I think the best thing we can do is let HTC know, this way It will be taken care of on future product releases.
Interesting post and I am glad the issue is being brought to daylight. It's not fun having a $400(+) phone have a $300(-) look.
Did you work in Frisco? I work in RP at the Jefferson Commins site.
Add me to the list, my ok button is completely scratched off, I thought it was just me :-D
add me to the list also my call button is chiped off were can we buy replacemet buttons
Wow this many ppl need new button decal and we all dont have a clue where to get it... I almost went as far as trying to get a replacement phone from t-mobile just so i could get em but sadly that didnt work out...
As I stated before, it really didnt pop up until about 6-8 months after starting using it. Its coming from the little magnetic clip on the holster.
If not replacing the decals....what about the buttons? Is there anywhere you can buy just the front keypad.
I know you can buy a housing for about 55 bucks, may be worth it. Pretty sure that the front keypad comes with it. I found this...
http://cnn.cn/shop/tmobile-wing-housing-p-1839.html
From that page:
"The camera cover and buttons are not included"
not a bad find at all, i think the buttons they are talking about is the keyboard seeing as those are the only ones missing. And it does say it has front keypad
Yeah, add me to the list too. My end button is starting to chip. Seems like a big problem. You think they would have maybe made the buttons clear plastic and painted them from the inside so it wouldn't scratch.
Add me too!
So I have the same problem as you guys. I know a lot of people whose buttons are completely clear now... I found this site, but i wish i could just find the buttons to buy too. Any help would be appreciated.

that's way too much just to replace the buttons.
To the guy that thinks it's his case: It's not your case. It's these cheap ass button. I don't use a case at all and it came off. Why couldn't they make it the same quality as the send/end (green/red) buttons? I'm sure the Herald users aren't having this problem.

On my first wing the send/end buttons were chipping too. Like you said, a combination of cheap and poor design.

Screen Loose After Prolonged Use?

So my Prime's screen gets "loose" (clicking sound when I squeeze the front and back of the Prime) around the volume rocker area after I use it for a while. It seems that it spreads farther and farther as I use it longer and longer and after I leave it for a while it goes away.
Also, when I press hard on the screen at aprx 2 inches from to top left pointing towards the center, the screen turns black (not off, but black).
So what should I do? It is not bothersome enough (yet) to send back to Asus for repairs but should I call them to let them know and record the problem on my Prime's serial or something? And do you guys know how long the whole process would take if I send it back to them for repairs (Im in Canada).
Thanks
Mine does that too. I think it's a common characteristic and read about others who have also remarked about it. The TF101 had something similar as well.

Does it also only get loose after prolonged us? Is it because of the tablet getting warm?

Beats me, I've had mine for 3 weeks and it's been about the same all along.
I haven't noticed any clicking on mine, but my screen sticks out from the casing a little bit (evenly - all sides). Does yours stick out, too? I figured it was just a poor design choice by Asus. And if yours does, that could be the reason for the clicking since there's probably some wiggle room.
same issue here near volume button... i hear clicking sounds... made me bit worried...

My SGS2 Vibrate is messed up!

So it happened this morning when my alarm went off and it vibrated. I heard a plastic part vibrating also. The sharp loud noise was disgusting. I shut off my alarm thikning it was my cheap SGP case.
Later today I played around trying to find out if the silicone had a hole or something where the plastic frame was touching the SGS2 phone itself. Nope. I took the whole case off. Each time it vibrates it sounds like... ahh what the hell. I will film it for you guys now.
http://www.youtube.com/watch?v=_GoIrBmMC1U
WTF is that? I took the cover off. I took the SIM card out on another occasion too. It sounds like something on the upper left. If I push my finger down on the panel, it stops. If you notice the few seconds it is sitting on the table flat, it's fine. Just a little weight seems to calm it down. Not sure if its the vibrating motor itself because it is vibrating properly. Sounds like something is loose inside though...
Anyone experienced this before? Should I go for RMA?
Second part of the question:
Obviously being an XDA-er I'm rooted. I will flash back to stock and unroot. I bought this off of Expansys-USA so I should get *some* reasonable attempt by them to send it back. What are the chances that my warranty gets denied? I don't have a USB jig to reset the counter, but I'll of course get rid of the yellow triangle.
*grrrr... I need to dig up my Nexus S now if I have to go through warranty... I'm guessing I'll be phoneless for weeks*
I don't know if it would invalidate the warrenty or not (technically rooting/custom roms is supposed to), but when I had a problem with my stereo jack not working rather than risking it I just replaced the part myself.
The vibration motor, stereo jack and earphone speaker are all on the same part.
(I got it from this guy on ebay for about $7 if you're curious.)

I see. I'm not sure whats broken really. When I shake my SGS2 I hear something rattling inside. I'm just afraid to open the thing up... is it difficult?
Just watched your video. It sort of sounds as if somehow the vibration motor came loose from its proper spot and is now moving around vibrating against the plastic. Its normally held in with some adhesive (basically double sided tape) within a cutout area.
When I had mine apart I actually took a photo, http://i.imgur.com/fgN9F.jpg, if that makes it any more clear.
I actually recorded the process of me reinstalling the new part (excluding the disassembly, there are lots of clips of that from other people on youtube) but havent gotten around to uploading it yet since my internet connection sucks and the file is nearly 2GB.
Edit to add:
No it wasn't really all that difficult to dissassemble, it was actually pretty easy. That said I enjoy taking things apart and trying to fix them. This was the first time I've dissassembled anything as small as a cell phone, but I'm used to taking things apart and trying to fix them when they break. If you don't have any experience taking apart electronics you might want to think twice or just pay someone who fix's cell phones to do it.
If you're thinking about it, heres a video where someone shows taking it apart to get a rough idea of whats involved.
http://www.youtube.com/watch?v=QKztg1ra4-0
I decided to try and upload the video I took, once it finishes (in about 2.5 hours) it should be viewable here:

thank you for your detailed writeup. im going to try this. ive taken apart my macbook pro to install an SSD before, and a few other electronics, but i'm not the very best (i feel clumsy sometimes), but i'm willing to give this a shot.
The only thing I'm worried about is that I could potentially mess up the phone in other ways in disassembly such that my warranty won't be honored if I need to resort to that... We'll see tonight. It looks like you used two screwdrivers? Which ones will I need? I have a #000 that I see will be needed for the back plate at least...
k. opened my phone up.
i just took the screws out and the backplate. i pushd around to make sure things are tight, and they seem to be.
put it together and the vibrate thing happens VERY rarely now..
I shook my phone around and still heard something shaking (please tell me if this happens).
I opened up my phone and the camera module seems to be loose. Is it supposed to be glued down?
Just to let you know, you say you don't have a USB jig so your Flash counter may make your warranty void, but, if you flash to an ice cream sandwich ROM (Cyanogenmod 9) you can install an app called 'Triangle Away' which will basically get rid of the Flash count and yellow triangle - it needs root by the way. (search it up on XDA, it's by chainfire')
Then you can flash stock and send in for warranty.

I don't remember it being glued down. Its been a few month since I fixed mine but if I recall correctly it just fit snugly in place between some plastic fitted walls.
This is the camera module you mean right?
Edit: I also don't hear anything shaking with mine, did you mabe leave a screw loose inside?

Yeah. Camera module. That's the one. The main 8MP shooter. It's not glued down or anything. It shakes around inside. I definitely did not leave a screw inside because I only opened the back panel and I put all the screws back in.
It's weird because something making noise while shaking the phone has been documented here:
http://forum.xda-developers.com/showthread.php?t=1254520
And I noticed that when you activate camera it goes away. Quite strange but as an engineer this makes me wonder HOW that even happens? Shrug.
I'm waiting for my Samsung Focus S phone to come from the Windows Phone challenge and I'm contemplating using that for a month while my i9100 goes out for warranty. Of course I can always use my Nexus S as a backup, but part of me wants to force myself on a new platform for a month and see how that goes... Hahahaha.

Hey Random6, did you happen to find that after replacing the vibrator motor with a new one, the intensity is now less than when new? I used double sided tape, but with 1.5mm, I guess the motor won't vibrate AT ALL.
Also I found that if I don't screw the one that seems to be closest to the vibrator motor all the way in, it obviously vibrates harder, but not hard enough.
I also used two very thin copper plates to sandwich the motor between the plastic plates, but once again, that was too much and the vibrations were not transfered to the phone's body, but I could hear it doing its job.
Any suggestions?
Thanks!

Loose Power Button

This may seem a little OCD, but is the power button a little loose for everyone? I popped my case off really hard and I feel like I might have pulled it hard and messed something up. This is loose compared to the volume rocker though. Replies would be appreciated and call my nerves some.
Thanks!
My power button seems "squishy" while the volume and home buttons are more "clicky."
I'm guessing it's normal. I keep thinking the same thing when I take my case off and put it back on....
Haha thanks I was expecting someone to rip me for that post haha. Makes me feel 100 times better.

I asked the danish Samsung support and they answered, that it is normal that the powerbutton tilts up to 1 mm.

does anyone have a loose volume rocker? i understand the power button and figured that's how it was supposed to be, but the volume rocker is different in comparison. if you lay the phone flat on a surface, on mine i'm able to wiggle the volume rocker up and down. so front to back of the phone. anyone else's like this?

My volume rocker wiggles much more than the power button. If I tap the phone anywhere near it gently, it even rattles.

looks like Sammy failed on the hardware this time. in comparison, all buttons were solid on my international SGS2 and my international GNex. it may possibly be because of the coating of the band around the phone and thus they had to use a different process.
edit: i will add, however, this is the very first Sammy device with no screen issues i've ever had. no banding, no bad spots. nothing. i was quite please in this area.
I might just deal with it. The ink spots aren't bad at all on my screen. Of course now I notice the rattle more.. Just moving it forward and backward semi swiftly makes a rattle noise.

yeah i'm worried about getting one with a bad screen if i get a good rocker. just fail.
received my second device today and i can confirm that there was a little more play in the first device. the volume rocker now matches the power button, on the second device, in regards to wiggle/play. cheers!

I'm an idiot... What's the small hole at the top of the V30?

asd
The small top hole is one of the microphones. There's an identical one on the bottom of the phone. So, you can make stereo recordings.
https://goo.gl/images/VqxsYw
The earpiece actually turns into a 3rd microphone for high decibel environments, like live concerts.
But that top one is one of the two "regular" microphones.
Thanks, I thought so. Is it only for recording, or for noise reduction too? Recording I don't care about. Also, should I plug it with glue?
Mastiff said:
On autopilot I was going to put in a SIM card in my brand new phone and pressed where the hole was on my previous phone. Bad mistake, I guess... I probably put it right through something vital. Because I used the small hole at the top of the phone. Not the side. The light wasn't all that good, so I didn't notice that there was no SIM holder there. My guess is that it is a mike of some sorts, but I tried to record sound and had no problems with that. And it seems like there's a mike at the bottom of the thing too. So what did I mess up this time?
Edit: And does this mean that the phone isn't water resistant anymore? Can I stuff a bit of black silicone glue (the type used in bathroooms) in there with the pointy tool to make it water resistant again?
Edit 2: Oh, please drop the idiot jokes. I know it! Googling I have seen that I am far from the only one that has done that, I just would like to know exactly what it is on this phone, and if I should plug the hole to keep i waterproof. That's rather important for me, because I am an avid hobby crawfish and crab fisher and will probably get water splashing over this.

Aren't there barometer measuring apps for that ?
I read that by checking on pressure you can find out if your phone is still water resistant

If you don't want to tackle it, cell phone repair shop can.
That top mic is probably used for noise reduction during phone calls (since it's the top mic and you would speak into the bottom one), but used for recording stereo when actually recording? I'm sort of guessing on this.
If someone who is audio has better answer, jump in.
zacharias.maladroit, I have also read that. But I have read that it doesn't work as well, since the holes "breathe", they are mes of goretex or similar material. But I'll try anyway, thanks.
ChazzMatt, Interesting, thanks! Looking at that video at around 4:55 it may seem like the pin must have penetrated to the side of the microphone! I think I see the pinhole to the right of where the actual microphone is. As for fixing it, I am far to clumsy. But using a shop is of course an option, the only thing is that the phone is brand new and I'm guessing I'll loose the warranty for that. But I think I will first of all find out if the microphone isn't damaged, and then I will see what happens when I cover the hole. If it doesn't change the call qualty I will probably choose (at least for now) to glue shut that pinhole. If it is a problem for call quality I can maybe live with that using a silicone case and a piece of electrical tape over the pinhole when I go out to fish.

Yeah, 4:55 - 5:30 on that video shows taking out the old mic and putting in the new, for anyone else who needs to do it.
