[Q] Squeaky/Noisy Buttons on MT4G

I'm on my third MT4G because of squeaky/noisy buttons. The biggest reason why this happens is this:
1) the buttons are cheap plastic
2) the sides of the button rub on the phone's bezel, thus creating the squeaking sounds
3) the home/back buttons are in fact one solid piece (stupid design)
I'm thinking about putting some type of lubricant in my phone (per a suggestion over in the T-Mobile forums), as I highly doubt T-Mobile would provide a fourth phone to me. This squeaking sound really is annoying, and should not be present on such a high-end phone such as this one.
Has anyone taken their phone apart in an attempt of making the creaking sounds go away? Has anyone applied lubricant to the buttons to stop the squeaking?

lubricant?
you could try some sort of graphite lubricant... it's not really a liquid, just a powder and shouldn't propagate through the phone. i think "dri-slide" still makes it

The whole bottom of my phone squicks and creaks but I don't think I want to put any lubricant in my phone. I'll just wait a little and exchange it if anything. Doesn't bother me as much as I thought I would when I found out about it.

How bad its it? My vibrate feature is starting to maker noise
Sent from my HTC Glacier using XDA App

I sprayed a little bit of CRC Power Lube onto the left button on my MT4G since it was making an annoying noise when pressed. Works perfect and it's plastic safe, no stains!

Mine screams like a banshee now.
This is probably the only real design flaw with this phone.
Still better than non-responsive capacitative touch buttons, but def annoying.

I also forgot to mention how loud my home button makes this clicking sound when I press it (along with the squeaking sound). It really is f'n annoying. Could any of these lubricants help simmer that down a bit? If I had known these buttons would end up being so damn loud, I would have second-guessed buying it.

[Q] HTC HD2 weak wifi signal

Hey i installed gingerbread android 2.3.7 on my phone again but this time im getting really weak wifi signals... i'm only 5 feet away from router. It was not like this before so i do not know whats going on ( i only dropped my phone twice)
can you guys help me? is it a software issues or hardware?
happy thanksgiving

I would recommend installing a few different roms (that are known to work with wifi) and see if anything changes/improves.
If nothing improves, maybe flash back to winmo 6.5 and see if wifi improves.
If nothing improves then, you may have damaged your wifi antennae when you dropped it then hit up T-mobile!
Best of luck mate.

Possibly knocked the wifi coax loose from the mainboard. It's pretty easy to open up an HD2 and reattach that cable, I've had mine come loose before and that's what I had to do.
I'd definitely try the steps in the above post first just to make sure it's not a rom or kernel specific issue. And if it's still under warranty, don't bother taking it apart and ruining your warranty, obviously just return it to t-Mobile.

hey can you explain in more detail how to push back the wifi coax cable your talking about

Remove the battery cover, battery, sim card, and sd card.
Remove the 4 torx screws that are under little round stickers under the battery cover.
Using an old credit card or a plastic knife, slide between the screen and the housing to release the little plastic clips one by one which hold the housing to the phone's chassis.
Take your time and be careful not to scratch the housing or stick the card/knife in too far, damaging the fragile stuff inside,
It helps to put a little pressure on the back side of the screen wth your thumb while orying with the credit card (back of screen under battery)
The wifi coaxial cable runs from one corner of the mainboard, up along one side of the chassis, is taped together with some other wires, and leads to another small board up near the top of the phone.
Check the connections at both ends, making sure they are connected firmly and are in straight.
You might want to unplug them, just to be sure and hear/feel them click into place.
Take your time, set yourself aside a nice little workspace, and if you are unsure of anything, don't hesitate to come back here and ask.
There is a disassembly video here in the HD2 section somewhere, I think it's in HD2 General. It'd be worth it to search for it and watch at least the first part of the video, just to get an idea what you're dealing with. It's not a very hard job, it should take you like maybe an hour/hour and a half start to finish.
This will void your warranty permanently though.

Thank you sir i just followed the steps you did and it fixed the problem my wifi works fine but now i have another issue....
i dont know if i touched something or disconnected something in the process but my sound, vibration and volume button does not work. External speaker is not playing any sound (no music or key button taps) and no sound is made when placing a phone call BUT the other person on the end can hear me just fine so i'm guessing i might of disconnected like the speaker. ( my assumption)
thanks again for your help

Oh and when a call is being placed or recieved the screen automatically turns off and it becomes non responsive i.e if i take my phone off the ear and want to put it on hold the screen is still black instead of turning back on

The screen going black during a call is a pretty common problem with the HD2, and is likely not related to disassembling your phone as long as the screen functions normally otherwise. Since you didn't take your phone far enough apart to affect the light/proximity sensor, I can't imagine how disassembly would have affected it. You would have to take the mainboard and screen out from the chassis to get to that sensor.
The volume problem on the other hand, is probably due to either your volume rocker not being placed correctly during re-assembly, or the speaker contacts not being aligned properly. You'll have to take it back apart and ivestigate what went wrong.
Try going into Settings/Sound, and checking that the volume is not turned all the way down. If the volume is not all the way down, then you should be able to hear sound, so your speaker is probably not aligned properly.
Does your volume rocker feel different than before? If it doesn't make a definite 'click' when you press it, then it is probably slightly out of place. Also look for any wires that could have been pinched and damaged when you snapped your phone back together.

What is a volume rocker? When i start the phone it usually vibrates once then goes through the starting procoess. Now it doesn't vibrate at all. Phone turns on and i click the volume button up and nothing happens. I checked settings and everything is up
I have the phone opened as we speak and the reciever cable is connected and the vibrator cable is connected too. I tried to use tweezers to see if i can unhook it but their on too tight so thats a good thing. The two orange dots on the volume thing.. the bottom on was slightly off so i put i centered it
Still nothing works. no vibrating no sound ( the person on the other line can hear me but i can't hear anything) but the phone works great.
Im so confused

The volume rocker is the button that 'rocks' back and forth to control the volume.
It has to be positioned right in order to push the contacts that lie beneath it.
Since your phone's apart right now, what happens when you hold the battery in it with one hand, boot it up, and press the volume button contacts manually? If they buttons themselves do nothing, then it must be that they lost their connection somewhere, you'd have to trace the wires and figure out where they're not connected. If they do work, then the volume rocker was just misaligned.
As for the speaker, it has to be that it is not contacting the two little contacts correctly. Look at the speaker and make sure it is sitting correctly in the housing, and look ffor any obstructions near the vibrator motor.

No i can't press down on the volume button ever since i opened it it hasn't fit back right. Doesn't make a click sound
and what contacts on the speaker should i be looking for? are they under the speaker itself? should i remove the speaker? Theres no destruction on the vibrator its looks though like its sitting kinda tight between that camera flash being there..the metal spinning thing on the end of it can spin 360 so nothing its preventing it from moving.

I also can use my headset and the sound and call works fine besides the going to the black screen and not responding. i also noticed my camera does not load up either. but that could probably be solved with a clean install of gingerbread nand rom

HD2's innards: Attempted vibration motor fix gone horribly wrong.. HELP!

I'm hoping somebody with some knowledge of the HD2's innards can help me...
My vibration stopped working on my HD2. I found the plastic LED flash cover to be 'pushed in' (with the help of a couple xda threads I dug up). Others said it was an easy fix: Open the case and push that piece of plastic back into place.
I opened up the case to correct it. But after putting it back together not only does vibrate not work, but the volume keys, speakers (both earpiece and speakerphone), flash, notification led, and camera all don't work.
I obviously screwed something up, but I have no clue what it could have been. I was very careful. One thing I'll note is that when I pulled the case apart, the plastic volume rocker went flying. When putting the phone back together I got it back into place so that I THOUGHT it should work (it was seated properly and felt "clicky" for up/down movements.
But clearly wasn't just the volume rocker that was affected. It doesn't seem that I pulled anything else loose or anything like that...
But no luck, all that I listed above is non functional, and what I'm left with is a glorified 3.5 in tablet
Any ideas?? Thanks in advance!!!

Snapped a couple quick pics which may help:
http://i50.tinypic.com/mmsa36.jpg
http://i47.tinypic.com/sl1kdx.jpg
Unfortunately when comparing these to other pictures of the inside of the HD2 that I found online, I fail to see any differences, or anything I could have inadvertently screwed up.

Most likely you screwed up(or disconnected from motherboard) somehow your main flexboard, but your picture are not usable for this, you should take off your motherboard+main flexboard from chassis to have a full view!

You probobly just disconnected a small cable. I have no idea of the HD2 innards but did multiple repairs of small stuffs and the flat cables hold in place by a plastic clicker pull out easily - just reopen and check them all, you should be fine.

Thanks for the input! I figured it's something like that, just one small cable. But I didn't even take off the board at all... The pictures show the full extent of the disassembly... Do we still think it's necessary to disassemble it further?
I checked all visible connections, but yeah, maybe I somehow yanked out something that is NOT visible. I'll try to check again today... In the meantime, any more ideas from anyone else? Thanks!

For al that to be not responding I would assume main-flex damaged or as mention before maybe connection to mainboard got moved during pulling cover !
Volume button can be troublesome, sometimes the little plastic caps come off but if it felt clicky should be good in that respect.
also be very carefull of thin spring metal legs that contact antenna pads on back cover, one near screw above & right of vibro motor looks a to be a bit flat. They bend easily & break easily too ...

Have u tried starting up the phone without the backing? I had this issue when I painted my housing the led cover was stopping the motor from spinning but if i took out the backing it works. So I just trimmed the led cover and now it works.

I'm nooby with regard to this stuff; I only attempted the repair since I read in a couple other threads about multiple self-proclaimed non-super-tech savvy people were able to open it up and move the plastic LED cover for an easy fix.
So what exactly am I looking for with regard to the main-flex? Where is it? I thought I wouldn't really see that unless I removed the board which I haven't done... is it still possible I knocked it loose or damaged it? I didn't think that would be possible since I ONLY removed the back cover (though it does take a slightly uncomfortable amount of force to do so, so I guess anything can happen...).
If not the main flex cable, is there anything else specific to look at which may be disconnected? It seems to be all the stuff at the top of the phone that fails to work (camera, speakers, vibration, flash, volume keys). While the stuff on the bottom (other hardware buttons, charging jack, headphone jack, etc).
THanks!

I have given up. After being stumped briefly how to hard reset the device without the volume keys working (I have Android installed), I was able to do it via ADB from the Android dev kit.
To ebay I go...

S4 screen stays off , please help.

Hi,
I'm hoping someone can help me determine if I have a defective phone or no. Basically what happens is that when I receive a call and I bring my phone to my ear the screen turns off (as it should ) but when I move the phone away from my ear the screen stays off and I have to press the power to bring it back on. Mind you this started happening 2-3 weeks ago, before it was fine bring phone to face/ear screen turns off , move it away from face the screen would turn back on.
Now logically it seems the proximity sensor might be having issues but it works fine when i bring it to my ear so maybe that's not it?
This is quite annoying whenever I'm on a call and have to press numbers, end calls, go back to what i was doing I have to continuously press the power button. I googled these issue and a few people are reporting the same thing. but i didn't see any solutions or answers.
Thanks for any help.

Ive had the same thing happen. Go to Settings > My device > Call Settings. Look to see if the option to "turn off screen during call" is enabled/disabled.

I feel like you have a a custom rom, or maybe just rooted with some cpu clocking going on. whats usually going on is your phone is going into a deep sleep where it's energy is to low to even force itself to wake up.. but it's still alive not dead, just unresponsive (I feel like I'm talking about malnourished human beings). don't let your phone get too weak, set your minimum cpu speed a little higher than what it is now, and make sure it gets more complex carbs.

I have not changed anything on the phone, it's stock and simply have accepted the carrier's OTA updates and that's it.
And also I should have mentioned that I did check the call settings, I have the "turn off screen during call " enabled, before posting here I had that option disabled but then the screen would stay on during a call, which is worse cause then the phone gets hot near your face and don't want a bright light next to me.
Also I did a hard reset and factory wipe and nada, still doing the same thing .

same
I have the exact problem with my s4. I will post any findings.

Got It
For me, it was dust inside the phone in front of the sensor.
How to fix
1) Remove back of phone along with the battery and GSM and SD cards.
2) Remove 4 screws around the back of the speaker. Then pry out ward from the battery compartment and pop out the speaker housing.
3) Remove 5 screws from the rest of the back. Use your thumb nail and start at the bottom and work around the phone to pry appart.
4) Remove 1 screw from the camera and sensor housing. Pry the metal cover off by starting at the top and pry upward.
5) Take the camera out by on snapping the bottom snap plug with a flat head tweaker. Then remove front facing camera.
6) Lastly take out the sensor snap plug and tilt the sensor out. Blow air inside the housing .
7) reassemble.

My ear messing with calls

I keep disconnecting or putting people on mute whatever with my ear, is there a setting to turn the screen off during calls?

Is this in the native dialer?

Your phone screen should automatically turn off when you put your phone to your ear.

That's odd and wrong, the proximity sensor is about 0.5 cm left to the camera cutout, make sure you don't:
Have a dirty display
Use an invasive case
Use a badly applied screen protector, some glass ones can cause problems too
Cover only the left side of the screen with your ear
What software are you on?

I've had the same thing happen a couple of times. The prox sensor is too far to the edge of the phone so it doesn't always "see" my face when I hold it up to my ear. I had the same issue with LG G7.

It's happen to me as well but I don't really mind since I text more often than I do calling people ?

Can you replicate the bug by playing a WhatsApp audio file(can be your own) and covering the top of your phone?

It's easy to replicate on a call. Hold the phone up to your left ear and just slightly rotate it away from your head. You'll see the screen come on. It all depends on how you hold phone while you're talking.

Yes, I've tested the proximity sensor and it works, so it's more about how I hold the phone it seems. I take a lot of calls whilst on the move and i pace about a lot whilst talking.
It seems the screen is going on and off and my ear is touching the screen before the sensor turns it off again.
For someone who makes 30 or 40 or so calls a day the problem is me and the fact I'm never sitting at a desk when doing so.
I need to work around this with an ear use routine lol

very old thread, but i suffer the same issue, even with all the updates. only when under lineageOS the proximity-sensor works just fine. bur lineage is no solution, unfortunately.
Did you ever manage to really solve this ?
best regards from switzerland

The issue of the Prox sensor is one as old as smartphones. My questions and advice usually go like this,
Do you have long hair that drapes over your ear? Hair that hangs in front of your ear is not always solid enough to be detected. Light can also bleed through and cause false signals allowing the screen to stay on. There are two ways to overcome this, press the phone tightly to your ear. This compacts the hair and blocks the light. Some don't like this because of the pressure. Pull your hair back before placing the phone to your ear.
Are you sure of the device placement? Everyone's ears are different and sometimes the sensor can miss the ear. Slight adjustments forward or back can land the sensor on a solid portion of the ear rather than a recessed area. Also holding the phone too high can be an issue as your ear is actually under the sensor. Figuring out ear placement becomes muscle memory and can change from device to device you just have to find the spot first then make an effort to hit a few times until it's natural.
Is your screen clean? Ironically a dirty screen can cause issues with these sensors as well. If the screen is dirty from makeup or natural oils in the skin the sensor may have a difficult time realizing there's a difference and not react. Just running your palm over the upper portion of the screen right before placing the device to your ear should be enough to clean the sensor and provide a contrast reference.
Most of you have tested your sensor but for those who haven't if you continue to have issues it is always possible that there is a defect in the sensor. If none of the above advice has worked it's a good idea to test both the Prox and light sensor. To test the light sensor, set your device to auto brightness and in a well lit area place your palm over the upper portion of the phone, the screen should dim. To test the prox sensor, place a call or have a friend call you and place your palm over the upper portion of the screen, the screen should go dark with no display.
If all of the advice fails and the phone also fails the sensor tests you may need to take the device in for service.
A temporary solution would also be to not hold the phone flush against your cheek while on calls. There are no controls at the top of the phone and muting or disconnecting comes from cheek contact. The mic on the device is very good. You'd actually find that you could sit the phone on the table and talk to someone in a normal voice and they would hear you just fine. You obviously wouldn't hear them as well if not on speakerphone, because speakerphone both boosts the volume and incorporates the second speaker. So even if you held the device a few inches or CM from your mouth the other person would still hear you just fine. This is another technic that requires a bit of practice but can become second nature with the added benefit of keeping your screen a little more smudge free.
