[Q] The back button under the screen not showing up! - Defy Q&A, Help & Troubleshooting

Hello,
I am a Moto DEFY owner and my back button at the button of the screen is much much dimmer than the rest..
It was OK until a few days ago. Don't know why, but, ONLY the back button is not lighting up, it seems a little bright(may be light from other buttons), but it is not working.. The key is fine to use and it responds.
I haven't rooted or done anything to the phone yet..
I would appreciate this deeply if anyone could help me..
Thank you

RW6828 - Any button turns it back on

Hey,
On my JAMin I have the option in settings to stop any button from bringing it back when I've turned the screen off by tapping the power button (or whatever actually happens when you do that). Among the many things that annoy me about the HP firmware, I've found that the RW6828s also don't have this option in settings. Is there anything I can do?
Thanks,
James
I'm really sorry to bump, but this is a huge pain.
Does anyone have any idea on this?
press and hold red buton... the other buton will be locked

[Q] -sigh- g1 'rainbow screen' - EXPERIENCED USER(S) please.

i'm sure this has been done to death, but, through my searching, i haven't found an actual concrete solution.
i purchased a g1, knowing that it was stuck at the rainbow screen. i thought it'd be an easy fix, but, in my case, it seems not. i'm a uk user, so have flashed the rc7 update, and NOT the 29 one. yes, i pressed the camera button, and THEN the power button, whilst the g1 was turned off. once successfully flashed/completed, i press the 'action'/trackball key, take the battery out, and turn the phone on, only to see that the rainbow screen is STILL there.
what you might need to know:
DREA110 PVT 32B
HBOOT-0.95.0000
CPLD-4
RADIO-1.22.12.29
Sep 2 2008
Serial0
so, if anyone has a full-proof solution that will get my g1 working again, i'll be extremely grateful. if not, i'll put it on e-bay. is it possible that my g1 is permanently bricked?
How about NOT pressing the trackball?
However note that pressing the trackball during bootup SHOULD put the thing into BLUELIGHT mode (debug console).
Typically, if it turns on straight into the bootloader, it means that your CAMERA or BACK button is stuck. Try pressing each of those buttons a few times and then turning it on again. If not, you may need to disassemble.
but, i mean, once the phone says Update Complete
UPDATE SUCCESS,press action (trackball) key,that's when i press the trackball key, as it tells me to. the camera and back buttons certainly don't feel stuck, ...

He is right, if it boots into bootloader (rainbow screen) that means your camera button is stuck, even if it doesn't feel like it.
i just took apart my htc dream... im experience a similar problem.... i measure the ohms on the switch for the camera button, open, it shows about half contiunity on my multimeter(analog), and when the button is pressed, it registers a full short, as it should, on both sides of the switch. I will try unsoldering the camera button at some point tomorrow, and will try to post my results.
does anyone know if those switches are meant to be completely open when not pressed??
EDIT: will be heading out to my job in the next hour to use the hot air station to remove the camera button, and clean up the contacts on the board... if this doesnt work, does anyone else have any other ideas??

ok, so i just unsoldered the camera button off the main board, and it still comes up to the bootloader.... what next?? ive flashed the dreaimg.nbh file, and wiped the phone. i can press the home and pwr button and get the recovery menu, but even there, flashing anything *.zip doesnt make a difference... ideas now??
EDIT:So i just got another g1 with a cracked screen... i switched out the mainboard. with a different mainboard that worked from a different phone, it still came up to the bootloader screen... i then switched the buttons, not the camera button, ironically, the other buttons.. i switched the whole front plate(send, home, back, end, menu buttons/trackball panel). now the original mainboard works fine... just no camera button cuz my hot air station at work killed the button. try that and let us know here. see if that works for you....
EDIT2: Heres a thread that i just opened with that last explaination, as well as a story to how my day preceded with this phone... http://forum.xda-developers.com/showthread.php?t=781143 enjoy!

display wake up

Hi all,
i sometimes notice this problem on my omnia 7..
when the screen is turned off and i press the middle button the screen is not turning on.. i have to press it again or press the power button.. anyone experienced this problem?? any idea what can it caused?? I do not have any apps installed..
Thanks..
I have the same, sometimes the middle windows button will not wake the phone up.
When the middle button refuses to wake up the phone the camera button also refuses to wake up the phone and go straight to the camera app. I need to press the power button and then the camera button.
Annoying.
Do you guys know the term "it is a feature" when something in reality is a flaw - well in this case it really is a feature
If the sensors notice that the phone is in a complete dark surrounding it assumes the phone is in a pocket. Therefore it not wakes your screen up and also the camera button will not work. You can test this if you hold your thumb over the sensors next to the speaker strip.
Should your camerabutton not function in a bright setting, it is of course a different situation.
What an easy and clever answer..
Thank you very much.. next time i will think more.. OMNIA 7 rulezzz
Aaaah clever stuff!
Superb thanks

Home button not working correctly

Hello everybody,
I've bought my titanium silver S7E a week ago and have been satisfied so far.
Last couple of days, I've noticed that the home button is only responsive if I click on its center and a bit to the left.
The edges of the button and the whole right side will produce a "click" sound, but won't really press the button.
The fingerprint sensor integrated within the button works just fine.
Anyone else has this issue?
Thanks in advance for your answers.
no issue
There is already a thread about this home button's issue here: http://forum.xda-developers.com/s7-edge/help/flaky-home-button-t3337431
I had also the same problem and i went to Samsung Greece. They told me that the home button is manufactured to working properly only at the centre and they have no information about this issue.
But they seen the button's problem and they change my screen (button and screen are together).
Now the problem is not gone but its better than before....Im not happy about...
