Several have noticed the limited number of sats the GPS fixes on and the lag in fixing plus "jumpiness" of location on the built-in GPS.
I have an idea... an accessory request, unless somebody knows of a reason this shouldn't work.
We have the GPS cover on the back and the ext. GPS antenna jack just under... How hard would it be to make a very small external antenna that is much better than the built-in?
I'm thinking you take off the GPS cover entirely and plugin something shaped like a jacket button... goes into the jack, maybe uses the places the cover attached for support, is fairly flat against the case... maybe just a wire from the jack out and in a spiral, enclosed in plastic...
Well, would it improve the signal? Only slight complication is it'd need a warning to be sure to pop it off before trying to slide the whole battery cover up.
Hmm... or maybe an entirely new battery cover that had a built-in antenna and a flexible way to connect to the GPS jack... Maybe another version to for the cellular antenna too, for people who need more signal strength?
What does everybody think?
Nobody thinks it'd work?

I think you'd be better off just getting a bluetooth GPS receiver.
Hey guys, today my g1's reception kept on going from X to 4 and what not. When I got home there was nothing. I know its not my SIM because it works in a different phone.
Recently I replaced the earpiece speaker and things went smooth. When I opened it up I saw the GPS connector was barely connected, so I plugged it in firm and closed it up. Still no reception. Opened it up again and found that I had screwed into the wire cutting it!! I then soldered the wire together and made sure everything was correct, STILL NO RECEPTION!
Is this a possible antenna or other hardware malfunction? The phone works fine otherwise.
Ok so the digitizer on my milestone went bad about a month ago, i ordered one off ebay and installed it myself. unfortunately while doing so i ripped the flex ribbon that has the sensors attached to it. went on ebay again and ordered that part and installed it, didnt destroy anything this time.
put the phone back together and everything seemed to be working fine, then i got a call, the person on the other end couldnt hear me and the proximity sensor caused the screen to go blank even before i put the phone to my ear
if i put the phone on speaker phone the person hears me but its very low im told, inserting the headset works fine, person can hear me perfectly.
i tried doing a recording with the phones sound recorder and all i hear is a hissing type sound when i play it back, i also downloaded an app to test the proximity sensor and its showing a distance of zero and when i put my finger near and further away from it its still saying zero.
tried doing a battery pull..hard reset, reflashing the froyomod that i have install and nothing seems to work, could this be a defect with the flex ribbon i bought? would this ribbon affect the microphone?
any help would be appreciated
Thanks
I also damaged the flex ribbon while changing the digitizer... where did you get the ribbon? Anywhere in the EU?
got it off ebay..it was shipped from china
bump........
I have the same problem and it's the effect of the digitizer replacement. Light can get access to the sensor between the digitizer and the sensor. If you press the left upper side of the digitizer the proximity sensor is working again, very annoying during calls. I tried to put some spongy tape behind the sensor and the metal backing plate it's better but not perfect.

Luvkillin, have you been able to fix this abomination of a mobile phone? I had a malfunctioning digitiser and replaced it, after that the microphone stopped working so i thought that I had broken the microphone. Changed the audio pcb and turns out that its still not working. My prox sensor also doesn't work but with all the other problems this is just a nuisance.
I found that motorola couldn't be arsed specifying the second microphone that is on the logic board and some acting as noise cancelling. I installed a db meter app and picks approximately 25db except when the phone rings which goes to 65db. So if the noise cancelling module is disabled by software, the mic could work without changing the logic board.
Did you manage to fix it?

No i havent, its just sitting at home in a drawer
i also installed a db meter app and got a consistent 16-19db when the phone is not in use. i assumed that it was too much of a coincidence that everything was working before and as soon as i changed the cable and digitizer they stopped working. plus the digitizer and cable i bought was for the milestone a855 and i have a a853. when i checked they seemed to be the same but i guess not.
im planning to just buy a new digitizer and cable for my phone specifically and see how it goes.

I believe its the noise reduction microphone damaged at some point in the disassembly. Did you check the 3 gold pins on the right upper side of the logic board?

Yea i did. dont see any damage at all to the pins or the board
The same problem here. I've changed digitizer and my proximity sensor stopped working. So I thought that I broke it during the work. I've ordered new main flex with the sensor. It was much better but still not perfect. But microphone went down. I think the problem is microphone board or the flex cable that connects it to the mainboard. Did you manage to solve the problem? I've ordered new mic and new flex.

Nope..still no fix
did that fix yours?
anyone knows how to disable to noise cancellation microphone?
Hi guys,
to refer to the proximity sensor issue, i'd like to point you on my old post over here:
http://forum.xda-developers.com/showpost.php?p=9810999&postcount=8
Please check for the rubber...
Concerning the microphone, this might be related to the electrical contacts of the mic.
Please make sure again that everthing is right in place.
Would not harm to check the flex cable connectors as well.
Regards,
scholbert
Solved problem
Hi to all,
I had problem with my proximity sensor, it didn't work at all. (I had cm7, cm6 and cm9 rom)
I installed stock rom and it works again. ))
Microphone problem
Hi all !, I'm having a similar issue after change the digitizer, I'm not having any issue with the proximity sensor ... but is not the case with my microphone, when I answered a call my voice is heard into the speaker and the other person didn't hear me .. somebody found a solution to this problem ? Thanks all !
Had simular problem after replacing digitazer. if i press hard on upper side of the screen, then for some time everything comes to normal. So i desided to heat it up using a hair dyer for about 10 minutes, than press as hard as i can and wait till cool down. now everything is fine.
I've spent hours reading the various threads since getting my HU last Novemeber. Absolutely love it, especially with the Malaysk roms on, does everything I could want it to, except make a bloody phone call. If the other end can hear me it's very faint at best.
Mine was supplied by Pumpkin, they have tried to help with a microphone app and various settings, none made the slightest difference.
There were a few posts about adding an external mic by finding the BT card after dissasembly and wiring to the mic+ and Sgnd legs on the card. Last night I eventually bit the bullet and took mine completely to piecese. Unfortunately I couldn't find a BT card, maybe it's built in, or on chip or...... But I gave up looking for it. What I did find on the front panel was the original pathetic little mic, way back from the tiny hole. You can't drill it bigger as it knocks the mic out of place.
My fix, made simpler now I know what I'm doing (it took me a lot longer and many more steps.
Take off main case
Pull tape off DVD drive to extend ribbon cable
Flip up black tab at the back of the ribbon cable connection on the screen and slide out ribbon and put screen aside
Remove two small screws from the side of the faceplate and using a flat blade screwdriver release the faceplate
Flip up tabs on both ribbon connectors and remove ribbons, I found it easier doing the short one first
unscrew all circuit boards screws in the faceplate circuit (7) and remove faceplate
Drill a hole in the rear of the unit above the ISO connector to feed a cable through
Carefully desolder the horrible little mic from the right hand side of the circuit (labelled mic1) and clean the holes
Take a mini jack extension lead and cut off the male end - either a mono one or if stereo you want the wires for the top part and the middle part of the connector stripped and feed through the hole, I also put a very small tie wrap inside with the tag outside so I could hold the wire tight and not strain the solder - tightened after assembly
The positive (top part) goes on the inside connection. I soldered this to the top of the board
The ground goes to the other terminal - these are so close together that I soldered this on the underside to ensure no contact
Reassemble in reverse of above (making sure all faceplate buttons are in place (yes I forgot the eject and screen buttons)
Then connect any unpowered condenser Mic and all of a sudden fantastic vocie clarity, quite a phenomenal difference.
I used this mic from Amazon, https://www.amazon.co.uk/gp/product/B01F84YMZQ/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
Happy for this to get merged into another thread, but I couldn't find one specifically about the mic problem with the single din unit.
Was there no factory fitted connection for an external mic? Mine does have one. Then it would be simple to just disconnect the internal mic right?

No, no external mic connection on the single din units. Confirmed by Pumpkin. Bit of a silly oversight
Hello all,
So the main microphone of my z3 compact came off the motherboard along with the solder pads. Now i can see a tiny little metal connection exposed on all the 4 pads. I ordered a microphone, soldered it back on the board, but failed all microphone diagnostic and service menu tests. I de soldered the mic again, to see if the contact were lose. While removing the mic, i could see that one of the two pins of mic on the motherboard are shorted, unfortunately the little track came off as well. Anyway, i soldered the same mic again on the board (using a hot air blower), shorted the two pins on the mic, but it still does not work. Now my questions:
1. While testing the microphone, i might not have connected the headphone flex connector to the motherboard. Is the primary microphone somehow routed through the flex connector of the headphone jack?
2. Where is the secondary microphone?
3. Any work arounds, if i cannot solder the mic back on? Can the connections be bypassed somehow with jumper cables etc?
Any advice will be much appreciated. I just dont want to get rid of the phone.
