I was hypothesising, don't get my K750 until next week. I'd be suprised if either the phone or the USB driver has the functionality to selectively turn off the charging function, never seen this capability in a phone before.
Hassan, if u whant performance & overall stability go nokia, for multimedia & small form & design go SE. I have 6230i and i whant 2 sell it, dosn't worth the money, i'll go k750 as soon as i can.
Make sure you turn off all of your pop-up blocker and firewall. And make sure that you downloaded the java client from www.java.com
See with youre own eye's, cmos is much better than ccd sensors.
recently got my k750, love it except for one little issue. i am having trouble woth my bluetooth as it wont allow me to accept an incoming call from the headset, only the phone but upon answering the call the call is transfered to the bluetooth. if anyone has helpful info for me please let me know
CCD vs. CMOS
The comparison is like apples vs. oranges: they can both be good for you. DALSA offers both. CCD (charge coupled device) and CMOS (complementary metal oxide semiconductor) image sensors are two different technologies for capturing images digitally. While they are often seen as rivals, CCDs and CMOS imagers have unique strengths and weaknesses that make them appropriate to different applications. Neither is categorically superior to the other, although vendors selling only one technology often claim otherwise. The choice depends far more on the application...and the vendor.
Both types of imagers convert light into electric charge and process it into electronic signals. In a CCD sensor, every pixel's charge is transferred through a very limited number (often one) of output nodes to be converted to voltage, buffered, and sent off-chip as an analog signal. All of the pixel can be devoted to light capture, and the output's uniformity (a key factor in image quality) is high. In a CMOS sensor, each pixel has its own charge-to-voltage conversion, and the sensor often also includes digitization circuits, so that the chip outputs digital bits. These other functions reduce the area available for light capture, and with each pixel doing its own conversion, uniformity is lower. But the chip requires less off-chip circuitry for basic operation. (For more details on device architecture and operation, see "CCD vs. CMOS: Facts and Fiction"
CCDs have been the dominant solid-state imagers since the 1970s, primarily because CCDs gave far superior images with the fabrication technology available. CMOS image sensors required more uniformity and smaller features than silicon wafer foundries could deliver at the time. DALSA founder and CEO Dr. Savvas Chamberlain was a pioneer in developing both technologies in the 1960s, and his leadership helped bring CCD technology forward. Only recently has semiconductor fabrication advanced to the point that CMOS image sensors can be useful and cost-effective in some mid-performance imaging applications.
CCDs offer superior image performance (as measured in quantum efficiency and noise), and flexibility at the expense of system size. They continue to rule in the applications that demand the highest image quality, such as most industrial, scientific, and medical applications.
CMOS imagers offer more integration (more functions on the chip), lower power dissipation (at the chip level), and smaller system size at the expense of image quality and flexibility. They are well-suited to high-volume, space-constrained applications where image quality is not paramount, such as security cameras, PC peripherals, toys, fax machines, and some automotive applications.
Costs are similar at the chip level. Early CMOS proponents claimed CMOS imagers would be much cheaper because they could be produced on the same high-volume wafer processing lines as mainstream logic or memory chips. This has not been the case. The accommodations required for good imaging perfomance have limited CMOS imagers to specialized, lower-volume mixed-signal fabrication processes. CMOS imagers also require more silicon per pixel. CMOS cameras may require fewer components and less power, but they may also require post-processing circuits to compensate for the lower image quality.
The larger issue around pricing is sustainability. Since many CMOS start-ups pursue high-volume, commodity applications from a small base of business, they must price below costs to win business. For some, the risk will pay off and their volumes will provide enough margin for viability. But others will have to raise their prices, while still others will go out of business entirely. High-risk startups can be interesting to venture capitalists, but imager customers require long-term stability and support.
The money and attention concentrated on CMOS imagers means that their performance will continue to improve, eventually blurring the line between CCD and CMOS image quality. But for the forseeable future, CCDs and CMOS will remain complementary. Each can provide benefits that the other cannot. DALSA's approach is "technology-neutral": we are one of the few vendors able to offer real solutions with both CCDs and CMOS.
you have to make your 3ggp-mpeg files on your pc so you can sent the 3ggp or mpeg4 file to your phone with infrared or usb cabel so you have to update your quick time player to pro
there is no phone that can play rm or ram files only 3ggp or mpeg 4 files you can make this files withe quick time pro 1 convert the rm or ram files to mov and so you can convert this file to 3ggp or mpeg4 the last is the best for your phone
I heve a new k750i..i tested it and i found that NOKIA6630 WITH 1,3 MPX I BETTER THAN K750 WITH 2MPX!!Dont let anyone fools you...!!Nokia has the best cam!!But this phone is stylish,long lasting batery 265000 display....but still dont have fast internet...where is EDGE?data transfer is poor like from the last century...
guys pls help me: i have a 6230i(not 2 happy with it) if i have the money is it worth selling it and buying the k750? pls answer.
Leon: The camera ont this phone and Nokia N90 is the best around, perhaps change the settings but this phone does have a CMOS sensor which won't use as much battery life but will have more noise! I am not sure if the sharp has a CCD or not which has less noise but uses a lot more power! But the quality of this camera apart from low lit conditions is way better than the GX30!
Yes you can assign a ringtone for one specific person like Nokie's!
Craig: No updating the firmware does not delete anything, just updates some stuff like improvments basickly to make the phone work better like making it faster and basickly just improving the use of the phone etc!
I am very dissapointed with the quality of the camera. If there are any dark areas on a photo (which there will be on most) the picture becomes very noisy.
My old phone was a Sharp GX30, which I could say coped with dark area BETTER than the k750!
I can't believe this wasn't mentioned anywhere on GSM arena before. I am particuarly dissapointed with the Sony Ericsson K750 camera review: Compared to the best.
Other than that this is a great phone, and would recommend it. But don't expect the camera to be "a step above the rest".
That's weird john, i didnt read any of ur cons in this forum - unloucky. Did any one face any of the problems that john faced (message below me), coz i'm willing to buy this phone this weekend.
Ive had my K750i for 5 days, thought it was a very nice fone but... im having a few problems with it, the earpiece is very quiet, even turned right up, it seems to have a problem downloading games, when it loses service you need to turn the fone off, then it wont turn on so you remove and replace battery, then the hands free fails to work, overall not very happy... not reliable enough... tried the new firmware download too but it doesnt work as already said, Vodafpone did tell me there is a problem with the software! will be exchanging this weekend.
hi, what does updating the firmware do? and does it delete all programs and files off ur fone, thanks.
:( i tried to update the firmware but won't work. Have u tried doing it urself? All the way till off phone is ok but after pressing "c" and connect the USB cable to the phone, the updater had no respone. Tried it twice but doesn't work also. Please assist me... TQ!
is it possible to set a specific ringtone for 1 person or a group like in the nokia
Thanks for giving the link out Tommy!
lostmaker: Are you sure m8? You should be able to stop it charging and transfer files from phone to pc! Try again or get help!
This phone does not play .rm or .ram files (i.e. real player files)
Leon: Lines are caulld noise and will happen in low lit conditioned areas as it is down to the sensor on the camera! It is a CMOS sensor that hardly uses any power but has lots of noise in a photo with low light conditions! Where as they are thinking by the end of Novemeber, it will feature a CCD sensor which will be a lot betetr in low light conditions and will hugly reduce the amount of noise in a lit area on the photo but takes up a lot more battery power but they almost certain to put one in this phone!
