211372 2004-01-30 23:06:00 Apparently there's a chip that says it attaches to your nokia 8250 phones and causing the keypad to flash when u receive a call.is this chip that attaches to the phone relaible?meaning it works and doesn't cause my fone to malfunction.
I saw it at trademe preparing to buy it but im not so sure

there are also chips that attaches to your battery that causes the keypad to flash.

211373 2004-01-30 23:55:00 Its not a "chip" as such as far as I know.
To replace/fit a "chip" to your cellphone is akin to brain surgery.
Not a DIY job.
Give the TradeMe link?

Its a relacement keyboard, with a strap connector that (hopefully) piggy-backs onto the battery connections.

Will it impair the reliability of the phone?
Yes.
It has to impair the reliability, as its being added and the maker did not design it.
Anything added increases the failure rate, thats a law of physics.

Looks kinda like a chip that attaches itself to the battery.
what Do u fink.looks suspicious.I heard from my sister a long time ago that u can do these things to a cellphone that makes the flash of the cellphone different.She didn't quite say how.I thought that it was the design of the maker to change the flash of the cellphone .I didn't expect there was an addon kinda thing like that !!

Looks nothing like a chip.

Its a whole replacement keypad that attaches to the battery. See my post above re reliability.

Anything that piggybacks onto the battery connections has to degrade reliability of those connections.

211376 2004-01-31 04:01:00 Would you happen to know how that the thing fits in?
Im not really sure how everything fits together and how it works.
The 8250 itself has a blue led.So the thing that is showing is a new keypad that plugs into the battery but wouldn't that affect the led of the phone?Huh?
Im not seeing a picture of how it fits in!

211377 2004-01-31 04:05:00 I've just increase the monitor brightness.Looks like a keypad now.But i was wondering how does the keypad reach the battery.Doesn't seem to fit.Do u have a explanation of how to fit that keypad into the phone? yingxuan (3330)
211378 2004-01-31 05:55:00 No

I dont have that model. And if I did I wouldn't fit it. I know when my phone rings, as the display lights and the phone rings and vibrates. I don't need the keys to flash as well.

Its very plain from the picture however that the flexible mylar printed circuit strap wraps around the innards of the phone to reach the battery terminals.

You will need to completely gut the phone to fit it inside the case, I have no idea how it replaces the existing keyboard, but it will probably replace the existing LEDs as well, as they will likely be part of the keyboard.

Pull your phone to bits to find out.
One assumes you have a working knowledge of basic electronics to install this device?
