Thanks @DoUL for your answers. i've got a friend who got a SE w550i and the transfer rate by bluetooth to another phone is also the same as me so i guess that's normal.

  • dj

The new firmware R1AA008 is for K750i or W800i?

Can i use bluetooth adapter to do the updating firmware instead of USB data cable?

Will this new firmware improve the battery life compare with R1N035? which one better?

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.
