You need to take your phone to a cell phone repair center and have them replace the headphone jack. The contacts aren't reclosing. If you found this helpful, please post as such. If you take it to the service center, please post this as fixya. TY

I cannot hear calls but they can hear me

Not much to tell you other than putting the factory software back on it. Thats the chance you take when you flash any phone.

No audio.

i'm having the exact same problem and not one person at the sprint store is willing to give me a straight answer. i found this on the internet:

I was able to make it to the Sprint store on Monday. The tech there told me that the Treo 755 series has this speakerphone/audio problem that they've been seeing alot lately.

Here's what to expect if it happens to you:

- your speakerphone button goes away
- you will not hear the phone ringing or anyone speaking at the other end
- you must use the headset that comes with the phone to hear anything - you most likely won't be able to use any other headset
- you will not be able to hear incoming calls but you will be able to make outgoing calls using the official headset only
- you can get your voice mail messages using the official headset only
- you will not be able to hear music, radio, tv, or any audio whatsoever
- soft or hard reset will do nothing
- your bluetooth headset will not pair with the phone

It's a real drag using those official headsets, how do people get them to stay i their ears I wonder? Mine keeps falling out no matter how I shove the thing in there. But at least I can use the thing until the replacement arrives.

Hopefully you've purchased the $3/month plan to replace your phone if it fails because you will need a new phone. I'm now waiting for the phone to come into the store, they're currently out of stock.

I think I've covered it all. I wanted to be sure to let everyone else know about this problem. Make sure you back-up & synch your phone alot to save your data.

hope that helps!!!

Can make outgoing calls, but I cannot hear anything. On speakerphone I can hear them, but they cant hear me

its hardware fault.your speaker is not working.try to disassemble the phone,check the speaker interface if there is a corrossion,clean the interface and assemble your phone again.try to make a call.if still not working replace your speaker.

Palm treo centro.

I had a frustrating problem, maybe the same.. No sound in or out of the phone, no "Speakerphone" or headset icons showing up on the "dialing" screen. after much frustration, hard and soft resets, etc. it turned out that an annoying and unwanted "voice dial" program had turned itself on and was screwing things up. I had to set it to "Never" use voice dial, now all is back to normal.

Treo 755 not able to make calls

The only workarounds I've read about these issues is:

1. Plug in the headset again and pull it out crisply and see if that works. Another method I heard, is to stick a toothpick in there.

2. Using the OEM Treo mono headset, insert the jack fully into the socket, spin the jack in the socket 180-360 degrees and remove the jack with a quick jerk. If the socket is truly undamaged, this technique, often repeated, seems to enable the speaker.

3. Some report that the headphone jack adapters, 3.5 to 2.5mm, work for this as well, that has NOT been my experience.

4. VolumeCarePro will bypass the headset switch and is a software workaround.

5. Otherwise, the only way I've been able to 'resurrect' the speaker is by hard reset, and once it took two hard resets.

As a result, I do not use my headset jack on my Treo 755p at all any more.

Unfortunately, this is an area that Palm is aware of, but has done little to fix.

is a hard reset

Palm treo 650

The 650 seems to have a delicate headphone/mic jack. Dropping the phone, even gently, seems mess up that jack. I returned my first treo 650 as defective, and got a new one. The same thing happened to my new 650 after I simply compressed the phone in my breast coat pocket by holding my mail against my chest.

I can't get a new one because the replacement treo comes with no warranty of any kind. :(

My advice would be to find a PDA/phone repair service to repair the jack or diagnose the problem if it turns out not to be the jack.
