    I have the exact same problem than Nyameba. When I try to activate the camera on the phone, I get a message that says "another application is running...."

    I have tried:

    - switching off the phone, taking out the battery and restarting the whole thing.

    - deleting all application that I could from the phone.

    - the master reset function

    - the update service.

    All of the above attempts/actions happened without problems but did not resolve our problem.

Although this is not a solution, I now know the cause of our problem.

After a bit of further investigation, I found that this is a hardware problem mostly caused by water damage.

a small connection lint corrodes or burns through. This can happen some time after the actual exposure to moisture at which point the phone will start with this problem. It seems as if this is a very common problem with the K800i.

I hope this helps all you frustrated K800i owners out there.

Sony Update program only updates the software. It does not remove any problem. I use it regularly.

Sony Ericsson :: K800i - Apps Or Games - Operation Failed

Check the file format of the application if it's compatible or not.

try to download here :

If you still got error on installing the applications,try to reset the phone. Go to settings > Master reset and choose if you want to reset only the settings or the entire phone,if ask for a code,the default will be 0000,but if you change the code before,enter your desire code and after that the phone will restart and it will go back to its original settings.

Good luck...

How to format K800i, i already tried to 'Master Reset'' the phone ,or sony ericsson update service. But still 'Operation Failed' when i open the GAMES and APPLICATION Folders, is it mean the phone should...

It seems that It is a Software problem rather than hardware.
you can udate your software at free of cost if you are having internet
Download the sony uopdate update manager and follow the instruction mentionde there on.

You must note that during such operatin your phone memory is formatted.
So you will lost your contacts and data stored on Phone Memory.
Therefore It is advised that you must back up your data before starting
the process.
If you does not have any software for backing up data, you can use
application called "My Phone Explorer". You can download the same from
the following link. It will back up your contacts too. But make sure
that your cell phon's drivers are installed before installing "My Phone
