K770i Camera Problem [ SOLVED ]

I'm using a Sony Ericsson K770i for more than 1½ years. Since I'm a novice and hobbist photographer my choice was that cameraphone.

Recently, the camera seemed to malfunction. When I open the lens cover, the screen switches between camera viewport and home screen repeatively. Sometimes it looked OK until I capture the scene. This behaviour made things more annoying.

First, I thought this could be a software problem. So I reinstalled the phone's software. But no luck. Then I googled for similar issues and Google took me to this forum discussion. But it also says the same thing.

After examining the camera's unusual behaviour carefully, I realized that there's a low probability of this being a software bug. The problem occurs randomly (not when I do a specific or unusual thing with phone's software). So this should be a hardware problem.

So what could be the problem? Casually I found it.

If you remove the back cover of your K770i phone, you'll see two triangular white tips at the right side of the camera. Now hold the battery with your middle finger and press the upper tip. What you see on screen is the camera viewport. Now try some captures. Will it switch between the home screen and viewport? No.

The problem is actually with the phone's back cover. Hundreds of times I have removed the back cover to change between SIM cards, memory sticks, etc. So it has become loose. It's obvious by looking at this phone, loose back cover means loose lens cover. Nothing wrong with lens cover itself. When you aim the camera, slight movemets of your fingers make the loose cover tighten and loosen, and that tip will press and release repeatively.

So I guess this might be a known issue with K770i. Time spans, back cover loosens.

To temporirily overcome the problem I adjusted the metallic plates in the lens cover. But I advice you not do so yourself and ask for support from a qualified technician.

So this is it. Don't waste time reinstalling any software. Thanks for reading the article.

In some phones it's the SIM card holder itself.
In some other it's the battery that gets loosens...
