In which mode is this happening? Handsfree mode or normal mode?

the best option is to upgrade ur firmware if ur settings and all are correct..
if still the problem persist..contact sony care !!

Ok. Let me assume :
1.If it is happening in handsfree mode, then the problem is with the cord of the Handsfree or the plugin link between mobile and handsfree
2.If it is happening in normal mode, then as Neeraj said, try updating mobile software from Sony ericsson website.

If the mobile is within warranty period, better take it to Service center. They must fix it for free.

R1CA021 is the latest version available as of today.
I recommend you to take the set to service center. They can't fix it in front of you. But nothing to worry dude. Don't hesitate. If you are worried about battery exchange, note down the number of battery before giving it for servicing!

R1CA021 is not the latest version...the latest version is R1DB001
Released on SEUS for the K750 on 14/09/06.

Software versions:
LCD 0
Camera 5.3

firstly try to upgrade ur firmware..if still the prob persist then the last option is sony service center !!

the problem that is coming in your handset is very common in k750i.

@Neeraj, Yep. You are very right. R1DB001 is released after R1CA021. But this update is not recommended. SE seems to have modified PHF_1_play.apf, PHF_2_play.apf and PHF_play.apf which tends to decrease the volume of mp3 playback!! This is a known fact. Just google. You will come to know about this bug.
Now most of K750i users who updated to this version are asking ways to get back! So this is not a recognized firmware update.

there is not much decrease in the sound output...i have compared it both the firmwares..(volume has been decreased by 2bars ,whereas the radio quality has been improved)
also ur camera gets updated from 4.5 to 5.3 and its worth to install it..
if ur camera is already 5.3...then theres nothing much to go for..

if u want to get the best from ur k750i...and its cid36 then update ur firmware to w800i..its worth it !!

Converting K750i to W800i involves some risks. If your set is with in warranty period, better not to go for firmware change. Warranty gets void. During convertion process make sure that there is no power failure or internet failure! This may lead to total set failure! Most important issue is it is not reversible. Do take these precautions.

no, updating the firmware via seus will only upgrade the software of the phone. cid36 is like batch number for the phone. the first lot of phones that hit the market were labelled cid36. ther were some flaws in this which let to its exploitation and hence the internal file system of these phones cud be hacked and customised. SE realised, updated it and the next batch of phones (the more recent ones) came wid the tag cid49.

lol......well if u try to connect ur CID49 ph with far...it will not show the system files u need to patched...

2ndly ,a guy wrote a mail back to me tht he did exactly as i wrote ,but ph is dead...:D

so if u follow wht i have written and still u have doubts..tht might u be wrong..then dont go ahead.....

my cousin k750i modded to w800i firmware...with all the patches...like without handsfree music button..etc
all u need is to read and understand everything carefully
for ur CID 49.......just keep it updated via SEUS..nothing more u can try till Darkman (far manager) finds a way to show CID49 system files :D
