Default Hot blackberry glitches

Please Login to Remove!

i was at a club last night and it was goddamn hot (not to mention I was hot and sweaty from being on the dance floor- great image, I know).

But anyway, my 8700 was in my front pocket and when I took it out to sms a friend of mine who had disapeared, I noticed I couldn't type anything because the mapping of the keys was totally messed up. Half the time when I pressed a key, it would type two totally random characters or even backspace. Even the return key was messed up. pressing return would give me "jk" every time- which made it a challenge typing in my passowrd- type, TW worked however.

So it seems that the blackberry doesn't like being in warm pockets. I didn't realize the operating range would preclude working in this circumstance. I would figure it would have to be WAY hotter for it to fail like this.

THis is the second time this has happened. THe first time I took out the battery for a minute and put it back in, and it worked. But I think it just had enough time out of my pocket to cool off just enough. However last night the club was so hot that I took out the battery several times to no avail. Good thing I wasn't trying to pick up at the bar because I don't think standing in a corner taking out my blackberry battery was going to get me any.

Could heating up like this cause long term issues? Or once the heat is removed, will things go back to normal without any future derogatory effects?

I dont see how heat can be such an issue to begin with when there are threads here of people that have dropped theirs in puddles only to take the battery out, take the unit apart, and then bake it in the oven at 150 degrees for a while to dry it out. I am sure that no matter how hot that club and all the dancing was that you had reached a temperature higher than 150 degrees, so I would look for other answers.

THe problem was only present when the blackberry was only recently removed from my pocket. Once it had a chance to cool, it returned to normal.

I would assume that had someone put their blackbery in the over, turned iton and starteed typing, it would be outside of the operating temperature range.

I realize what you are saying but there is no reason for it to behave the way it is just because it was a bit hot, no matter what temperature got in there I sincerely doubt that it could have gotten to more than 105 to 110 degrees and it should not have caused it to react this way.

yeah. i figured the temerature would have to be greater. hmm.
It is the only thing that makes sense however. THe ONLY two times this has ever happened was when it was in my pocket in a hot environment. And the problem rectified itself immediately once it had the time to cool down a litte.

There is a strong correlative relationship- there might be another variable or two. Who knows. I smell an experiment. haha.

Come to think of it.. 105 F is only 40 degrees C. Body temperature is 37.4 C typically. In an excited state basic body temperature can raise well above that. So in a hot crowded club, dancing and sweating, reaching 40 degrees is quite possible.

Here's the solution. In your Safety and Product Information Booklet, it says your BlackBerry battery operating range is 32 to 122 F(0 to 50 C).

Wel have you thought of this, Hot environment, close to your body, PERSPIRATION, moisture. I would say moisture might be more of a reason than temperatures of 105-110 when it is rated to as stated above to go to 122.

Besides what about all the men in the armed forces out in the hot desert using theirs?

I firmly believe that, while there is a slim chance, Blackberrys can function improperly when exposed to high or low temps. Think about your blackberry. Put it in the freezer for 5 mins or a little longer. Let it get nice and cold. The blackberry is slow an sluggish right? I dont know why this happens, but it leaves room for the possibility that High heat and perspiration can cause specific issues

KonTiki: Very possible. Just investigating possible options, hence the post.

Moisure could certainly be a possibility as well. However I can infer from the length of time it takes for the blackebrry to resume normal operation, that it is more likely heat.

Moisture seems as good an explanation as heat. In any event, MY blackeberry+my pocket+likely a combination of moisture and heat=funny behaviour.

It's funny because this was never an issue with my 7290.

Remember the dust issues with the 8700.

Have you ever taken your 7290 apart and put it back together, have you done the same with the 8700?

With my 7250 there is a clear snap as it goes into its place, and when you tighten the screws there is short of a solid seal on this thing, nothing will get through short of dunking it in a bucket of water.

I strongly believe that the buld on the 8700c (maybe the R as well since both of these were the first rushed out) is less than desireable. I think RIM has learned from it and possibly newer models are better built. I still do not like the feeling of even holding one in my hand. I would love to have one, the screen clarity is superior, and if Verizon were to issue one with EVDO I would be hard pressed to turn it down, but as I have stated over and over in these pages unless Verizon wises up and demands it be built on the 7250 format, I will stay with my work horse 7250, it is trustworthy, reliable, solid and just the best construction I have ever seen from RIM. Unfortunately they started to listen to too many people who did not like the feeling of putting a "calculator" to their ears to speak into. Well guess what there is bluetooth, give me a calculator then.

I've left my 8700c in the car, in Fort Lauderdale, on a 90 degree day for a few hours (I know, not a smart idea, but it was an accident) and it did not experience any issues like the ones you described. It easily had to be 110 degrees in the car when I got back in and the bberry was fine (hot to the touch, but fine nonetheless).

Sure they weren't her fingers you were pressing.

Could it be possible that the random keypresses from moving around with the device your pocket were the culprit? I've not experienced this with my 8700, but have had similar problems when carrying phones in my jeans pocket.

Static electricity can also create problems. Depending on the material of your shirt and shoes...its very easy to generate a damaging level of static energy.
