SE K850i menu touch screen button not working properly

My K850i is crazy now, the menu button (touchscreen) is not working, if you press 8 or 5 buttons they activate the menu button and at times you can't unlock the phone because the menu button presses itself, Can you help?

    SE K850i menu touch screen button not working properly problem

  • Manix1 Jun 25, 2008

    Taking the phone in seems to be righ step, a good help would be to know why this happens, I mean, is it a software problem? Hardware? why this happens to many SE K850i? is it a design issue? if so, the advice would be to throw it away. The SE people has it now, I'll let you know what they find out, if they are able to find something... Thx anyway!

Do you all have auto keylock on?

I had this problem it drove me nearly insane for 3 weeks, I took it back to the shop I brought the phone from to have it sent off for repair BUT they had no loan phone.

As a tempory soloution so I could still use the phone to make outgoing calls I turned off autokeylock. and have so far i've had 1 week trouble free it hasn't locked up once! I can still lock the keypad it appears in my phones case to be a software glitch keeping the keypad autolocked.

None of my touch screen buttons work..but they do sometimes so I'm guessing its a software issue. It's incredibly annoying.

The touch screen wont function with touch of the fingers.


Touchscreen not working
-----------------------------------------------------------------------------
Clean the screen with a microfiber polishing cloth.
Do not wear gloves while using the touchscreen.
Do not use the touchscreen with wet hands or immediately after applying hand
lotion.
Moisture affects touchscreen behavior in the same manner as it affects a
trackpad.
If you have a protective plastic sheet or film on the touchscreen, try
removing it, because it may be preventing the touchscreen from working properly.
The current application may be unresponsive; press and hold the Sleep/Wake button
on top of iPod touch for a few seconds until a red slider appears.
Then press and hold the Home button until the application quits.
If that doesn't work, turn the device off and turn it on again. Press and
hold the Sleep/Wake button on the top of the device for few seconds until a
red slider appears, and then slide the slider.
Then press and hold the Sleep/Wake button until the Apple logo appears.
If the device did not turn off, reset it. Press and hold the Sleep/Wake button
and the Home button at the same time for a least ten seconds, until the Apple
logo appears.

Sir, try reinstalling your phone. This will make the phone to be back to its original settings and maybe can bring the phone's touch screen capability back.

This was just suggested for the exact same problem with my StreetPilot 2620 and worked like a charm: (1) Disconnect any external GPS antenna. (2) Do not turn on auto engine. (3) Turn off any other peripheral devices. (4) Simultaneusly hold down the PAGE and MENU buttons while turning on the 2620. A prompt box will appear asking if you really want to delete all user data. Touch the NO selection. Then turn off the 2620. (5) Simultaneously hold down MENU & ROUTE buttons while turning on the 2620. (6) A self-running diagnostic program will appear. Allow it to run for a couple of minutes; check to see that all parameters indicate "PASS" or other indication of being OK. If any parameter is not OK, make a note of it for potential communication to Garmin, then proceed with the following steps (7) Turn off the 2620. (8) Simultaneously hold down the PAGE, MENU & ROUTE buttons while turning on the 2620. A SCREEN CALIBRATION adjustment screen will apear. Quickly touch the points indicated as the calibration program runs. At the end of this procedure, the screen will display a window indicating that the calibration either "PASSED" or "FAILED." If it "PASSED," continue to steps (8)-(9). If it "FAILED," turn off the 2620 and repeat this step. If, after three calibrations attempts, each one is "FAILED," then also turn off the 2620 and proceed to steps (8)-(9). (8) Turn on the 2620. Press the "OK" button each time prompted to do so. Wait for maps to load and for the 2620 to initialize, acquire satellites, and display your position. (9) Press FIND button, then touch the right-hand vertical screen position adjustment to scroll screen display down to reveal WAYPOINT selection box. If unable to select WAYPOINT, or if attempting to do so only selects an adjacent box, then repeat step (7), and return to this step. (10) When various waypoint selections appear, attempt to scroll down to a selection not visible when the list of waypoints first appears, and select one of them. If still unable to select WAYPOINT box, unable to scroll screen down (or if trying to do so selects a stored waypoint instead), once again repeat step (7). If successful,then proceed to step (11). Also proceed to step (11) if you have repeat step (7) but then still can't select WAYPOINT, can't scroll down after selecting WAYPOINT, or can't select a particular stored WAYPOINT. (11) Press the upper-right hand "X" to close out the FIND screen or sub-screen within that function. If unable to close the screen, press the PAGE button. (12) Press FIND button, and when selection screen appears, touch ADDRESS. On next screen, touch the STATE line and touch the ENTER A CITY in (name of state). When keyboard appears on screen, use it to enter your city, then touch OK. Continue this procedure to enter your house number and street name, then press "OK." If all screen keyboard keys not responding, repeat step (7), turn the 2620 off and on again, wait for it to initialize, and then attempt this step again. (13) Repeat this procedure several times if not initially successful. By the second or third run-through, the touch screen should respond fully and accurately. If, after many runs through this procedure, the touch screen still will not respond, the screen sensor probably will need to be replaced ($255). The foregoing procedure brought my touch screen back to life last evening, much to my delight. Do not be too concerned if the SCREEN CALIBRATION step does nto produce a "PASS;" on my third calibration attempt it produced a PASS but all of the touch screen points still had not returned to functionality. I was unable to get a PASS during the screen calibration step after that, but the many repetitions apparently nonetheless made the difference, as by patiently following the above prcoess for five cycles, full screen functionality was restored. Thank you for rating this solution. Good luck and save you $250 for something else!
