Re: Will there be a hardware revision for the buzzing issue?
Is buzzing issue linked with speaker? When my freerunner has removed case and I'm calling to someone I can hear silent buzzing. But I am sure it comes from back of the phone (near GPS antenna), not from speaker. It is really silent and I can hardly hear it with case putted on. It is there even if I use headset or mute speaker in alsamixer. It isn't issue for me, but I wonder if it is related to this buzzing issue or it's something completely different. Sorry for my bad English. I hope you can understand what I'm mean :). -- hiciu ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

This is probably caused y the high intermittent current the GSM-modem is drawing from battery, what makes coils and the ceramic capacitors on the current path act like little speakers.

That would be great, especially for guys in the community who want to start a repair business. Joerg Reisenweber wrote: Am Mo 17.

My interest in openmoko is kernel and bootloader related, and there's just somethings that can't be fixed in hardware despite the steady stream of patches I see on the kernel list. So I'm unclear if some issues like suspend, battery life amd missed calls are perhaps hardware issues? Just trying to make an informed choice between buying now or later.

Best regards, Robert s/can't be fixed in hardware/can't be fixed in software/ - R for A7 there's no bugfix changes to expect, except beforementioned big-C rework for buzz issue. There are some minor improvements on audio quality for headset stereo (1u-4.7u). That's no bugfix in the end :-/ Currently we are not planing any hw-fixes for known bugs, that didn't make it to A7 version, means we aren't aware of such bugs that could be fixed for A8. For an eventual A8 we are planning some minor layout changes (3 beads) to make even more sure buzz is gone. (maybe this might also improve situation of buzz while using wired headset for a call. However it's not aimed at that topic) All A5 and A6 versions can be updated to A7 version by cumulative application of the changes done from A5 - A6 - A7 (again that's nothing more than big-C for recent A6) All this to the best of my knowledge, without any warranty ;-) HTH cheers jOERG signature.asc Description: This is a digitally signed message part. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
[OM2008.9 - FDOM] Re: Will there be a hardware revision for the buzzing issue?
Dear members, I follow the list since October, although I own my Freerunner since July. I owned a A5 before I needed its substitution from my seller because the handsfree speaker stopped working so now I own a A6 revision. I live in Italy and my carrier is Vodafone. I noticed this (appeared in both hardware revisions): during a call, if the signal strength becomes lower than midrange (looking at the top icon, can't know exactly the level) the buzz appears, while in the middle-high levels I have no buzzing at the other side. Furthermore, when the signal is around the mid range, if I put my hand on the bottom side of the phone (I remember the GSM antenna is located in the arc under the hole) the signal increases a bit its level and the buzz disappears (not always but in a sensible number of situations it does). Maybe the buzz is relative (or not only) to the GSM signal strength so via software is it possible to amplify it or issue some commands to the modem to avoid it? My 2 cents :) Thank you for your great work from a proud Freerunner user ;) Bye! ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Re: Will there be a hardware revision for the buzzing issue?
Hello! Yes, this is hardware issue, and it's fixable. Right now openmoko folks are testing the solution which fixes this issue. As far as I understood it will make it to new hardware revision, but it's going to take a while - they have to test it first to be sure it's not causing new problems. But it doesn't mean if you buy your phone now it will have this problem - it depends a lot on operator, frequency and other stuff - some people have it, some just reading mailing lists and wondering what is this buzzing issue :) But in your place I would wait a little to don't have to solder it yourself.
