I bought a blackberry 3g about two weeks ago. Suddenly, it started scrolling all by itself. I'll be using the trackpad then the next thing I know it's not even on what I want! It's scrolling itself and typing all by itself. Its not water damaged, it's never seen water in itself. What do I do!! Its driving me crazy trying to use my phone like this!! Thanks

Is there a chance it was exposed to dampness? It doesn't take much sometimes to cause button and keyboard problems. Sweaty pocket? Very humid shower room? ...

Please update your profile with the exact model number of the BB that you have. There are many 3g models so it is useful to know exactly which one you have.

I'll resurrect this thread, because my wife is having the same issue. It is not a moisture issue as far as I can tell.

Any ideas? I'd take it a VZ store and ask, but you know how that goes.

My wife uses the very same model as mine.

Sounds like it got wet. Even a very humid day can sometimes effect a BlackBerry.

Interesting. Well that's a pain, but thanks for the information.

The idea that a humid day or some time in a bathroom that is steamy from a shower could permanently affect the operation of a smartphone just seems very, very wrong to me. To think there would never be the possibility that a user might get caught in a rainshower or their pants might get splashed with a phone in the pocket and not have built a device to be able to withstand the occasional accident just makes me scratch my head.

I certainly do not expect that a device could withstand a dunking, no matter how slight as water and electronics don't mix.

But a humid day causing keyboard or trackpad malfunction just seems to be a bit of a stretch and an easy excuse. If true it seems to me the manufacturer should be responsible for using inferior parts or for a design failure.

We are having the worst humidity/dewpoint we have all year here in NY yesterday and today. Will there be thousands of smartphones failing by tomorrow? I would have to doubt that.

There has to be more to keypad failure than humid weather.

Here is my experience: I live and work in a humid climate. See my profile. And I have stood in the rain in a hat and coat with my BlackBerry in a stock holster on my belt under my coat, more than once. Never a problem.

Reading the forum, when someone is asking about button and keyboard malfunctions and they haven't outright dunked the device, often through questioning you'll find out there was some exposure to moisture, such as a sweaty pocket or something. I remember one lady was carrying her BlackBerry down her top while dancing. Humid shower room is common. One guy believed condensation occurring when he left his car for the hot humid outside was causing symptoms of moisture exposure.

Again, I live a climate that is hot and humid. And I get in and out of my air conditioned car when it is hot and humid outside, and I do it all the time. No problem. Maybe it is because my BlackBerry is in a holster? I don't know.

At any rate, if you are having button or keyboard or trackball/trackpad issues and you can point to a plausible moisture exposure scenario, even if you didn't realize it at the time, then that is the most likely explanation. It doesn't make it the only possible explanation; just the first possibility to suspect.

In my opinion, given the symptoms described in the thread, THE first step is to remove the battery and give the BlackBerry sufficient time to dry, and then test. Maybe it is a hardware problem and not moisture, but if you don't treat it like moisture to begin with you risk ruining the device when it may be recoverable.
