Question about Sprint PCS Vision A640 by Samsung(r) Cellular Phone

1 Answer

Keypad won't function

Same exact problem. when flip is opened, camera comes on. No keypad buttons function except for END to turn on and off.

told by tech support that I could not fix. they will send me a replacement phone for $100.00 because I don't have a protection plan.

since I have fulfilled 2 year contract, I'm better off getting new phone for free (or less than $100), but renewing contract.

debating on going with another carrier. not too crazy about sprint.

Doro PhoneEasy 410 some buttons won't work on keypad


It maybe a flex problem or keyboard problem. The reason why I said it maybe a flex problem is because flip phones are fond of having flex problems because of the constant open and close of the flip. It makes the flex wear/worn out.
And it maybe a mere disconnection.
Which ever the case maybe, the phone needs to be disassembled in order to check/know what's wrong.
Regards.

How to lock a Samsung Intensity cell phone


Unlike flip phones, cell phones like the Samsung Intensity are subject to accidental keypad-pressing and dialing when they are in your pocket, purse, or even a holster. To avoid unintentionally using up voice or data minutes, you can lock your phone and temporarily disable the keypad.

There are two ways to lock a Samsung Intensity - the standard keypad lock and the security lock.

- To use the standard lock:

You can lock your phone at any time from the main screen by holding down the "0" key for about two seconds. The keypad will immediately lock, and you won't be able to use any functions or make any calls (except for calling the local emergency number). To unlock the phone, press the right option button (in the upper right corner of the keypad, next to the End button) followed by the Menu or OK button.

You can also set up Auto Key Lock, which will automatically lock your keypad after the backlight turns off. The Auto Key Lock setting can be found in the menu under Settings & Tools > Phone Settings > Auto Key Lock.

- To use the security lock:

The security lock also prevents your keypad from being used, but it requires a code to be entered in order to unlock the phone. To enable the security lock, go into the main menu and select Settings & Tools > Phone Settings > Security > Lock Phone Now. (You'll need to know your phone's security code in order to access this setting -- by default it is typically the last four digits of your phone number.)

To unlock the phone, press the right option button and then enter your phone's security code, followed by the OK button.

You can set your phone to go into security lock mode as soon as you turn it on by enabling Phone Lock Setting under the Security menu. Every time you turn your phone on, you'll need to enter the security code in order to unlock it. However, once you unlock it, it will remain unlocked until you either manually lock it or turn it off and then back on.

I have a 3/4 hp model 139.53990D from sears. My reomtes have quit opening the door. they will close it. The light on the control console blinks very lightly, not like when the lock is set. Door works...


The symptoms you give are exactly the way it is when the lock function is used. The wall control and the keypad will work but not the hand remotes. If holding the lock button for 3 seconds doesn't change it you should hold in the smart/learn button for 6 seconds. This will erase all remotes from memory and only the wall control will work. Now program it for the remotes and the keypad.

How do I change the code on our liftmaster 1/3 H.P. gargage opener


To program the keyless entry, first locate the smart/learn button. On the chain drive models, this button is on the end farthest from the door. On the belt and screw drive models, it is on the right side as you face the door from the opener. You simply press and release the smart/learn button. You now have 30 seconds to enter your four digit PIN number into the keypad and hold the enter button for five seconds. Wait one minute and test the keyless entry by entering your four-digit PIN number and pressing enter.

With some Security+ models, you can also program your Model 940CB Wireless Keyless Entry without climbing a ladder, right from your Multi-Function Control Panel. Simply enter your pre-selected code and press and hold the enter button on your Keyless Entry. Then press and hold the light button and the pushbutton on your Multi-Function Control Panel. The garage door opener lights will flash to confirm that the Keyless Entry has been successfully programmed.

To program the keypad, first unplug the garage door opener from the electrical outlet. Next, remove the nameplate from the console that the keypad plugs into and locate the program/operate switch. Flip the switch to program. Next, enter your desired four-digit PIN number into the keypad. Slide the switch back to operate, and plug the garage door opener back in. The keypad should be programmed.

Camera


Its designed so that the camera only works with the phone shut. There are no camera functions controlled by the keypad. For instance if your camera shield is closed and your phone is open if you then open the camera shield the phone will tell you to close the phone.

Frozen buttons except red end call button


This is a common problem, it has to do with the keypad flex. either the connector on the top part of your phone is unpluged or your flex is damaged. Open the top of the phone where the screen is at (4 torx screws) genlty remove the cover. you will see two connectors, one that goes to the camera, the other is the one you want. genlty pry it off upwards, I would also clean it with some IPA (rubbing alcohol) and a brush, re-connect it pushing down firmly, you will fill it when it connects. if it doesnt work, you can purchase a new flex, if you need repair help, let me know I can try to repair

Motorola ROKR e1 keypad problem


It's the problem with the keypad board, the hardware problem not software, clean the connector carefully and replace the keypad board with the new one. This will solve the problem. Regards.
