[XPERIA X1 Q&A, Help & Troubleshooting] Yaozer:
Gang,

I believe I've found a thread that describes a problem similar to mine:

http://xdaforums.com/showthread.php?t=552826

It talked about the camera folder messing up. But in that thread, at least they can still see the files, but having the wrong file sizes. Mine just vanishes.

Here is what I'm experiencing right now. I took about 10 pictures sequentially, was able to view them via Resco Photo Viewer (This has been my pic viewer ever since). Then after a few days when I wanted to show them to a friend, the contents in my \DCIM\100XPRIA\ folder in the SD card were all wiped out clean! Another thing I noticed is that every time I go into this folder, it takes a while before I get control of my phone again (around 10 seconds after), after that, it shows me nothing. I tried taking pictures again, the camera app was complaining about not being able to take the picture. The next thing I did was to rename the DCIM folder to "DCIM Temp", then created another DCIM folder. I was able to take pictures again, and guess what, all the missing pictures reappeared in "DCIM Temp"! I was able to open the pictures again. But again after a few days, the new pictures in DCIM\100XPRIA have gone missing. I tried the folder renaming technique again but it didn't work anymore. I couldn't take pictures again. The next thing I did was to change the "Save To" option of the Camera App to save to phone instead of memory card. I was able to take pictures, was able to open the pictures via Resco Photo Viewer, but then when I transferred the pictures to the SD card, again I couldn't open the picture. I was thinking it might be a faulty SD card, but how come only pictures that were taken by the X1 camera have this problem? All of my documents can be opened, pictures from other sources can also be opened, videos etc. Only the X1 camera pictures have multiple problems (either vanishing or can't be opened).

I currently have an R3A ROM, with a 16GB Sandisk micro SD card. I never take the SD card out, I always use the supplied USB cable to connect the X1 to my computer as a flash drive. I first noticed this problem when I still had R2A. But I never thought of it as a camera problem, because I just thought the SD card got corrupted when one time I pulled the USB cable from my PC too quickly, and got that "delayed write failure" balloon message from Vista. The symptoms I've experienced that time was the phone being unresponsive for 10secs when I try to go into some folders (like the DCIM folder I have explained at the start of this post). That prompted me to reformat the SD card and took the opportunity to upgrade to R3A. Right now when I step back and try to remember those affected folders in the SD Card (when still in R2A), I seem to recall all of them having at least 1 file that came from the camera app, like:

\DCIM\100XPRIA

\My Documents\My Pictures\Family

\My Documents\My Pictures\Gadgets

.

.

All the pictures the camera took go straight to \DCIM\100XPRIA, I then rename some of them and transfer to these other folders.

Does the X1 camera app have problems creating its output files? If yes, is there a patch or 'new' ROM I can install to get rid of this problem? I really hope someone can help me.

Thanks for your time.
