Question about Motorola Mobility RAZR V3

1 Answer

The phone has its own mind!!!

The keypad and the buttons at the top even keep pushing random buttons, it has gotten to the point that i can push anything else due to the keypad being in use. I have tried opening the back and blowing etc, but it still has the same problem, the button it seems to push the most is keypad number 7 (pqrs-inclueded). If you are unsure of the problem, basically if i don't touch my mobile at all and it is open (razor V3) the phone acts as though it has been pushed and it is usually keypad 7.
Please help

On 2 of the 4 handsets on my Uniden DECT 2080, the large middle button has stopped functioning properly. It's the button with caller ID, phone book, and arrow buttons. One stopped working about 2 months...


After having the same trouble with my DCX200 and not finding a solution online for the problem, I set out to find a solution of my own. The fix I describe below is probably more of a band-aid than permanent fix but it appears to be working great. The problem, I believe, is caused by the metallic compound that the manufacturer used on the push button contacts in this model of phones and more specifically with the large multi-function button. This compound appears to wear off quite easily with repeated use of the keypad. Along with this I think that the design of the multi-function button did not take into consideration the environment in which it would be used. Not everyone washes their hands and face before using a phone (does anyone?) and between grease, make-up and natural oils of the skin building up and eventually making their way down into the components, this may be a contributor to why these buttons are so susceptible to failure.

_889.jpg What you will need:
1) Small Phillips head screw driver.
2) Small flat head screw driver (not shown).
3) Goo-Gone, Isopropyl Alcohol or some other degreaser/cleaner.
4) Hole punch, preferably smaller than a "standard" hole punch. I found the one I used in my wife's craft supplies.
5) Cotton swabs.
6) Metallic or foil tape. Can be found at any home improvement or hardware store.

Step 1. Remove battery and two screws circled in red with your small Phillips head screw driver.
_891.jpg
Step 2. Pry off the dark grey back of the phone case with your flat head screw driver. I found that starting at the base of the phone and working around the sides was easiest.
_892.jpg
Step 3. Being mindful the the wires that attach to speaker take the dark grey back off of the phone. Next remove the screw circled in red below:
_893.jpg
Removing this screw will allow you to remove the circuit board from the front face of the phone to expose the numeric keypad as shown below. There is a thin white plastic keypad component that will either remain affixed to the keypad or the circuit board when you remove the circuit board from the front face of the phone. Be sure not to damage that.
_894.jpg
Take the white plastic sheet and affix it to the circuit board side (if not already on it), with the small black button contact points facing down onto the circuit board as shown below:
_895.jpg
Now soak one side of your cotton swab in your Goo-Gone or Alcohol solution and clean both the four small black push button contacts of the large multi-function button on the back side of the keypad and also the contact points on the circuit board. Then take the dry side of the cotton swab and remove any excess cleaner on the button contacts and the contact points. This step is critical. This cleans the surfaces and makes the push button contacts on the back side of the keypad ready to receive the foil tape.

Pictured below is the cleaning of the push button contacts of the multi-function button on the back side of the keypad:
_896.jpg
Also clean the contact points on the circuit board using the white plastic sheet as a guide to where to clean. Don't forget to use the dry side of the swab to remove any excess cleaner:
_897.jpg
Now the part that requires of bit of dexterity. Using your hole punch punch out four pieces of the foil tape. If you do not have a hole punch or are using a "standard" sized hole punch, you will want to try and use a scissors to cut out a small piece of foil tape that will fit over the black push button contacts of the multi-function key on the back side of the keypad:
_898.jpg
Harvest the small circles of foil tape that the hole punch punched out of the foil tape.
You can see a couple of them on my finger below:
_899.jpg
Now using your finger nail, gently remove the foil tape backing on these small circles. Yes, this can be a bit tricky, but I found it to be easier than I expected. With the backing off of the foil tape, affix your small foil circle onto the push button contacts of the multi-function button on backside of the keypad as shown below. Do not affix these to the circuit board contacts:
_900.jpg
Do this for all four contacts of the multi-function button on the keypad. The picture below shows the finished repair to the push button contacts. I also placed the white plastic film component onto the keypad side to underscore the fact that you place the foil onto the keypad and NOT the circuit board:
_901.jpg
Now place the circuit board back onto the front side of the phone (silver side) and fasten down with the screw you took out in step 3 above.

Affix the dark grey back of the phone onto the front side. There is a small plastic tongue at the top of the dark grey back that fits into a groove on the top of the front silver side of the phone. Get that tongue into place first then the rest of the back will snap into place.

After the back has been snapped back onto the front of the phone, fasten it down with the two screws you took out in step 1 in the battery compartment.

Put the battery back in, wait for the phone to turn on and try the keypad out. Below, you can see that I am checking the caller ID side of the mult-function button:
_902.jpg
This fix appears to work quite well. I don't know how long the repair will last but it would be easy enough to do again if needed.

With the phone ON, remove the battery. Wait at least 25 seconds (Use a watch) and put battery back in place. Then power up the phone.

The screen says F0 and it keep beeping. whats wrong?


One or more push buttons are stuck. Push all buttons at random several times each. Sometimes this will release the stuck button. If that does not work you will have to replace the keypad.

Phone is Randomly Calling People!!!


I had a similar problem where not only was it dialing the contact list randomly but also just entering keystrokes on its own (like it was possessed). Turns out there was a short in the top part of the phone (i.e. LCD screen part) due to water damage. The only thing the tech and I could come up with is that I used my phone when outside/jogging/exercising and sweat could have gotten in there. I had not spilled any liquid or drinks on the phone or dropped it in the washer....
