I'm not really sure if that's good or bad, I'll notice the transfer rate of sending and receiving next time I send/receive data to/from anyone, what I can tell is that bluetooth connection and transfer speed rate is very very pleasent to me in my K750i.

Of course not saying it's a FACT that will sure happen, it's just what happened to me. The fact which I can confirm is that battary gets to its full functioning state after sometime of using, say after 3-4 times of draining & charging.

They don't pull down what they did/reached in previous firmwares and start over from the beginning in new firmwares, use your brain man. When you upgrade the fimrware the new one replaces the old one completely as one package, you don't install a piece from here with a piece from there, you just set back and let the application do the work for you, you need not to worry about anything, after the application finished its work all you have to do is remove the cable and use the phone as if nothing changed, still you'll be taking the advantages of the improvments made in the new firmware.

K750i vs. W800i is already old news now, check previous pages to get to it. As for comparing with other brands I wrote it several times, not into answering this kind of questions, it's your money, your needs, your choice. You know each model pros. and cons. so do the comparison yourself. It's your brain so USE IT!.

1st of all the firmware upgrade will increase the video recording/capturing quality, not the play back quality, for as I said before it has nothing wrong to be corrected. N90 has a bigger screen so it has to support higher things not to have lag/tearing in video play back. K750i plays back any clip very smoothly and comfortably to your eyes, don't worry about it.

The software says what it wants to say, can you tell the difference with your own eyes or not ??!!

Yes. Both have same version of media player and both have same quality, differs only in loud & headset speakers.

They have to be of resolution 176*144 to be played back on the phone screen. Convert them into that resolution with any tool you like.

It support almost all kinds of picture formats and resolutions.

Same procedure but backwords. When you need to take a file from the phone to your pc you open the phone memory, open the folder which contains the file then select the file and copy it into the pc, backward that procedure to copy file from pc to your phone, select the file then open phone memory then open the folder of the file type then paste.

You'll lose the walkman feature once you get back to K750i firmware for K750i doesn't have this feature. Check this page to tell for yourself whether it's better than your current one or not:­2737&start=0

It doesn't show the picture of the message sender, only displays the name.

It takes 4 hours to fully charge the battary when it's full empty which reduces to only 2 hours later on -after sometime of device using- so I think your case is normal though I recommend you not to charge the battary as long as it's not full empty yet. It doesn't harm your phone nor your battary if you charged using the USB cable only it will take longer than the charger.

  • mijjy

  • daniel


the k750i plays clips in 3gp format right?? so what would the video quality be after the firmware upgrade if it was played in mpeg4 format (i ask this coz i would like to compare it to other fones quaility like the nokia n90 which has Bit rate 557kbps in mpeg4 format...

  • gwapz

hey @DoUL i meant their Headquarters.. where are their good phones made? i mean you know like nokia their headquarters is in finland and their good phones are made from there.. what about Sony Ericsson? Yes your right Company Ericsson is in sweden. I mean i had a P910i ones it was made in France.. thanxz for the CONS.. can you compare it to the W800? and is it worth buying? i mean the price is $359 + NYS tax.. what do you think? or should i just go for the Nokia 6680?

  • Tom

To @DoUL,

so if i upgrade straight to the R1AA008 version using that program on the SE website will it still improve the video quality or will i still need to upgrade the previous ones... or does that program automatically install the latest version (R1AA008) with all the capabilities of previos ones and the improvment versions (latest ones)?

  • jack

thanks doul i have kazaa v3 thanks 4 advice it is free!

  • dark_slayer

however, i called and asked the service centre and they said tat this problem is due to software problem in the phone. I am going the get it fixed soon. this battery prob is killing me. and i dun like it. are u all sure tat the indicator will come in a month's time?

  • buddy_84

sorry i mean transferring photos or videos to another phone using bluetooth. when i'm sending,the speed is 20kb per sec.i found it rather slow because when i'm receiving a file the phone display 40kb per sec

  • @DoUL

Go to several online stores/bay sites and pick up the models which are in your price tag/limit from the 3 manufacturers/brands. After you know which models are in your price tag read reviews about each and every single model of them whether in here GSMArena or any other mobiles site. Compare them side by side then go for what attracts you the most with its design and features. If you're not certain about a feature, ask in that model forum about that feature. That's how it has to be if you want the best for your pocket/money.
That general "what do you suggest" question won't bring the best for you, SE fans will recommend a SE model, so as Nokia and Samsung fans, each of them will try to seduce you to buy one of his fav. brand model even if that model doesn't have all the features which you actually need/want to be in your mobile.

The logo has nothing to do at all with the device performance as long as you're sure it's an original SE K750i and not a fake/imitated device. But 20 KBPS using what ?? The USB cable or the bluetooth ?? And transfering from/to what ?? The MS or the shared memory ?? Transfering speed isn't that static, it has quite some factors that controls it. I don't measure my transfer speed to tell whether if 20 KBPS is a good rate comparing to other K750i's or not but I can tell it's not bad for a mobile. Remember, its hard drive isn't as your PC HDD nor its precessor as your AMD or Intel processor. All in all, it's not highly recommended to transfer files larger than 3 MB using the bluetooth, and use the MS in transfering instead of the internal memory -for the internal memory read/write speed is actually very slow-, but try to perform a full format to your MS 1st to get the best out of it when transfering to/from it.
But how can you transfer with the phone switched off ????!!!!
