Question about Sony Ericsson W850i Cellular Phone
When navigating my way through the phone be it the menu or txt messaging the 'Back' Button ( right hand side touch screen button) keeps selecting itself when i push other buttons.
eg: wrighting a txt and i will be typing a word and on selecting a button say 'abc' ro 'jkl' it seems to trigger the back button which navigates me away from my txt and prevents me from continuing.
Problem solved. i had the same problem but i fixed it somehow. one day i just took a iron thick pin and pressed the space between number 5 and left-down button(not in the gap). and then i pressed between left-down key. Instantly it started working fine. i dont know whether it was my luck or i just accidently found a solution.

SOLUTION #9 WORKED FOR ME!!
Thank you prabhjeet128 !! I had the problem and couldn't fix it at all. I tried your technique of poking it around the D-pad and it now works! Thank you so much :)

Hello, I still own this phone more than 3 years, and i have fixed more than 5 K850i with the same problem.
so, if your touchbuttons are not working at all you have to remove the covers and clean the pads from dust, liquids, or what ever. just use alcohol and a soft ribbon
if your touch buttons are clicking around like crazy when your press other buttons (e.g. # 0 *) then your keyboard cover is broken, unlocked, or is not contacting tight the keyboard pad.
in this situation you have to press all the gaps (between the buttons and around the whole keyboard) with a BIC pen (disassemble the BIC pen and remove the writing nose first). if you do it right, you will hear a "click" sound witch means that the cover is again locked to its position.
>>>Firmware update is not fixing this issue

I had the same problem - dead touchpad. I followed the instructions to disassembly the phone in "Solution #4" below. Be careful, many clips to release before you can take the phone apart.
Locate the batteries. In the instructions, photo 3 you can see 2 batteries to the right, one third down in the phone. The battery with the yellow sticker is soldered in one end. Carefully lift the other end up, wait a few seconds then put back. Then assemble the phone. This worked for me, it might work for you. Do it at your own risk.
You can check if the screen is working before you assemble the phone. When assemble make sure all clips are in right positions otherwise the phone covers will be uneven when you are done. Spefically the small clear plastic "tongues" at the bottom of the screen. Should fit into the grooves in the top end of the key pad.

The middle button touch screen key presses it's self.! it's so frustrating, a minute ago i sms'd a friend and i havent bin able to write the next msg. my phone kept freezing, it was ok, then it kept restarting, i couped with that aswell, sometimes my inbox would empty itself, still ok but when this happened i had to do something. i master reset the phone, actually i just got into the master reset menu the phone did the rest and yes..Master resetting doesn't work either.. in trying to fix it i cracked the phone. I've loved all previous sony ericssons but this one's been a hazard since the day i bought it.

I am having the same problem, have had my phone for 10months and was working fine now my left touch screen button keeps selecting itself. So every time i turn on the phone the media menu opens itself and it takes me about 20mins to write a text because the options menu pops up after every letter. Its very frustrating. Will take it back to carphone warehouse today and see if they can fix it or just give me a new phone.
Didnt realise this was uch a common probolem - do y0ou think it is the same with all touch scree phones?

Thats exactly as what happens to mine, if i press number 8 it thinks im pressing the middle touch button, its annoying me now lyk, but its getting worse and it thinks im pressing the middle button no matter what number i press, keeps sending texts to people randomly, and wont let me unlock the keypad, just foned to 02 shop and they said they will send it to get repaired but that cud take up2 a month or longer, am i allowed to ask for a different phone if it dont work? never dropped it or anything, i think i might change to nokia or sumthing but sony erricsson phones always look good lol

My problem isworse than all of yours :(
my phones select button (left touch screen button) is selecting my itself but thats not all...when i bring my finger close to any button the select button clicks automaticly but when i keep my hands away it doesnt click :S Weird ...its like a ghost
Posted on May 20, 2008
This is due to the top face where the buttons are situated.It is because the front face is too close to the touchscreen pad you need to open up your phone using screwdrivers and remove dust etc. Look at this website oin how to disassemble your k850i case:-

I think the back button selecting it self automatically is a java virus... I installed a few games I downloaded and since then the back button clicks it self after I scroll around the menu for a while. I am going to try some flashing and resetting...

I have as well an K850i and suddenly it stopped working while im travelling, so im now stuck without a phone.
that's really annoying, i changed my mind about Sony ericson.

This has happened to my K850i too. Cant do anything with it at all except recieve calls. I took mine back to T-mobile where this bloke said told me it is not a manufacturing defect but a problem with the phones firmwear, whatever that is. He said he could have it sorted within 28 days OR i could have a go at doing it myself. He told me to type in 'K850i firmwear update' and look for a 'sonyericson.com' link finishing with 'K850i'. From there he said i should plug my phone to my pc via a usb and click on 'Download'. I havent managed to find this site yet, unless im being blind. But if any of you's can go for it. If not take it back to your place or purchase and they can sort it in a few weeks. They will probably give you a phone to use whilst yours is being sorted out. At least you know what the problem might be now.
