Headphone Jack stopped working - EVO 4G Q&A, Help & Troubleshooting

Somehow my headphones screwed up the headphone Jack. I took off the black tape on the back and noticed that if I push and hold the metal L shaped thing down it will work. Is there any way to fix/replace this?

In the same boat buddy. I think I read somewhere that if you take a cue tip and rip off some of the padding so it can fit with a little padding still stuck to it, you can clean it out a bit and then wet the tip with a bit of rubbing alcohol to get a better cleaning out of it. It may help or you could be like me and have hardware failure and need to take it in.

Hmm thanks glad to know its not just me. Do you have a link to that thread? What happened to you?

Conclude the a100 mic?

I know this has been mentioned many times and we all know how low quality the mic on the a100 is, but has anybody came to a final fix ASIDE from using a headset, through some of my playing around I noticed that the mic hole is actually lined up wrong, the plastic sides of the a100 can be removed, and when I saw where the hole is, it was positioned over a piece of plastic right beside the mic, and the mic itself is blocked.
So out of desperation a drilled a small hole right over the mic, that did seem to make the volume higher, but the quality...oh so worse (I had to fill that hole again with superglue, and it looks horrible), if anybody would like to see, just take the small piece of plastic off the side (it snaps in/out) and see for yourself how the mic hole doesn't even line up.
Now the second interesting thing is that I saw a chat session with a technical support guy at Acer about the mic on this tab, and he actually confirmed that the mic shipped with it is in fact a cheap low quality mic, so I was thinking, would anybody be able to somehow solder it out and swap it with a much higher quality one? Say from a headset or something, I don't have any mics of the same size as the a100 but if anybody has one can you maybe try and look into it, I sure will try as soon as I get good enough with soldering and find a headset, I mean we really don't have anything to lose other than a cheap mic that doesn't really work .
Much appreciated, thanks

Yeah, I'd like to see what it looks like inside before I start looking for replacement mics.
Alright, I will post pictures on how to open it up and how to get the microphone out, its tricky indeed

When I slide up my keyboard it gets stuck I was wondering if there is a way to lubricate it so it slides normally again

Tear it down and remove the sand.
I'd recommend while you have it apart that the sliding mechanism get blown out with canned air, wiped clean with an alcohol wipe, dried completely, lubed up with spray silicone lubricant on a Q-Tip, and any/all excess silicone wiped with a dry Q-Tip.
Can't find a teardown video, but if you've taken apart one cell phone, you can apply the same principles to pretty much any other. Get some safety pry's, a really small Torx driver, eyeglass repair kit for the philips screws, and rubber-tipped tweezers for any ribbon-locks. Just take it slow and diagram out the entire process on a couple sheets of paper, noting step-by-step.

Know what I did? Just hold it firmly, and slide it up and down untill it feels normal again... blow on it a lot too.

I took compressed air and blew it out and now its normal

good to hear. i once (more than once...) dropped my droid 1 in a puddle and it ended up with silt or some very fine **** in the slider. it would slide ok but just the feel of it, i knew there was junk in there. i put alcohol on the sliders and opened/closed it a few times, applying the alcohol like once a day for about a week then cleaned it out with compressed air. worked great. also worked well when whiskey ended up in there!

Actually, I figured out that the sand was coming from my pockets. Lol. I knew I was more responsible with my devices than that

Loose slider

I just noticed that my slider seems to be a little loose. Not overly loose, but enough to make the vibrate function sound funny. After a little bit of investigating, it seems it is the bottom slider that is a little loose. Is there an easy fix for this?
Hey when I first got my Glide The Vibration was an earthquake a month later...... What The Hell I can't hear it at all! Only when its set on hard surfaces like tables desk and other stuff like that and it makes a weird noise to so I'm having the same problem

I've completely disassembled the phone and put a loose spring back in. Not very hard to do, just be careful and don't rip out the video cable like I did

I get the odd feeling that that would produce obvious warranty-voiding signs...any other less-obvious causes?

Earphone jack damaged?

Basically no matter what headphone I use the sound is weird (as in right earphones doesn't work as well) and I'm sure it's not the earphone problem because I tested it on other devices and it was fine. How much would it cost to repair the jack? (I have no insurance or anything whatsoever)

Take a q-tip and get some 90% to 99% isopropyl alcohol, unless you happen to have some denatured alcohol around, which is even better... anyway with the phone off use the qtip soaked in alcohol to clean the jack out real well... it very well may just be dirty.
Failing that the headphone jack/vibrator motor is modular and very easy to replace so if cleaning it does not fix it you can pick one of these up ( http://item.mobileweb.ebay.com/viewitem?itemId=261082471428&index=1&nav=SEARCH&nid=63510570868) and have it fixed for $20... its super easy to take apart and change so I wouldn't worry about having to do it yourself. Good luck with it dude and you most definitely do NOT need a new phone...

Phone won't enter usb mode

For whatever reason, my phone stopped recognizing that it is connected to a computer via USB (nothing in the notification pull down menu to start usb mode etc). I was on slim rom, I tried switching to an old wild by night rom and it still has the same problem. Clearly it's not the rom, so I'm pretty confused. Trying to mount in CWM doesn't work either, and odin mode is not recognized on the pc. Charging via usb works.
Either your wire is busted or the solder joints on your port are cracked. Both are easy to repair.

Hrmm.. gotta wait till I get home to test with a different wire. How does one tell if solder joints on the port are cracked?
Visually inspect them. Its also a dead giveaway if no wire will work and nothing else is wrong with the phone.

I did a little more forum digging and found this old thread: http://forum.xda-developers.com/showthread.php?t=1344882
Sounds like exactly what happened with my phone (weird car mode that I've never seen before popping up; charges but doesnt connect to usb). Looks like you're right about the usb port. Gonna have to see if I can debride the area somehow...
If you are not experienced with or comfortable doing precision soldering, hit me up. Also shine a flashlight into the port and see if the pins are still in place. Bent pins can cause crazy issues.

Soldering is out of my cabilities, mostly because I don't own a soldering device. I do have access to dental equipment though, so I took a look using some 2.5x mag loupes with a light and I saw some some dust and white corrosion. I used a plastic periodontal probe to scrape out the corrosion, small brush to dust the port, and air syringe to blow it all out. Wamo bamo, it's working again.. hopefully it stays working.
Sweet deal man! Glad you got it all back to normal.

Bleh it was shortlived, or at the very least -- finicky. Seems like I may need to replace the port. Do you have instructions for doing that?

Not instructions, but it does require the ability to take the device apart and some fine soldering skills. Not really easy to make instructions for that. It takes a lot of skill to do it.
