Back button doesn't work. - GT540 Optimus General

Hello everyone! I have few problems with my phone.
First one is that sometime the back button doesn't work. In the recovery in the option which alllows to test button all buttons works fine.
And also when the back button doesn't work it's like the screen calibration is not good. For example in the dialer if i press the number 1 button it doesn't work but if i press the number 3 button it works but it's recognized as the button number 1 by the phone.
I'm actually on stock 2.1 rom before my last rom was SDSL 2.0
If somebody can help me thanks!

try to wipe data/factory reset. after this you go to settings and calibrate it (2.1 can do it, can't it ? )

Ok I'll try this. And yes stock version have screen calibrration but already tried this few time but it doesn't work.
Thanks for helping!
Edit: Tried this but still not working.

Could be hardware issue like mine. Screen calibration is very off and back button is not working when I press it it does not respond then when I press any part of the bottom half of my screen it opens the menu option? ??!?!?!?!?

Our problem is quiet similar. If it's a hardware issue I think we can't do anything

yeah lg??

lg?

Send to LG service

No I don't think I'll send it to LG Service because I think it will take a month to get it back. Otherwise I'll change my phone in few month so I'll do with it.
Thanks for helping!

Yep just like me hold on a few more weeks ..then change phone

Similar issue with BRAND NEW P-880
Back button works, but no LED behind it. Never lights up. Home and Menu light up, but not the back. Had the exact same problem with one I bought in Taiwan, also brand new. I think there's a batch of these that are bad and being sold. This one I just got off Amazon.
One obscure thread I found says it's a bad USB port/cable for the light issue.

help with the "talk" / "call" / "phone" button

hello everyone, i have the cingular 8525 and i noticed that when i press the green button with the phone logo to open the "phone" application (or to makes calls), it does not work...i dont think its the button itself but an issue with the software. i figured this out because I went to settings and and tried the "buttons" application to try to remap the button to the "phone" application however, i can only (re)configure button 1 (which is messaging) button 2 (which is internet explorer) button 3 (which is comm manager) and button 4 (which is the camera).....and there are no more buttons to reconfigure after that....i know i am suppose to have button 5 and 6 but they dont show anymore... any help would be deeply appreciated...thank you
I have the same prob, but my keyboard have a Italian setting. I think that this prob it's very annoying! Anyone could help us?
ive had that problem
Ive had the same problem, and my front buttons doesnt work, and it was hardware problem, send it to warranty.
hope usefull.
I have HTC TyTN and the same problem with call(green Button) it doesnt work at all.
When I want to enter the phone I press video call button , but could not make cals with green talk button , I should use talk button on screen.
Is there any help with this prob ?
Just fixed that problem.
The button didnt respond to normal presure , pushed it hard and it worked.
Pushed it hard 50 times or more and now it is working.
Probably the button needed some action to start working.
So what happened to "i know i am suppose to have button 5 and 6 but they dont show anymore" ? Oh, you just realized there was NEVER an option to change those buttons ? Ah, okay.

Have you tried restarting the phone? Press and hold the powerbutten (if it works), and answer Yes to the question about shutting down. Take out your battery for 10 seconds, put it back in and fire up your phone... It might help

Hehe, can't answer that. I've had the problem only like twice in three months, so for me it's not a problem... I guess it's a software problem. Remember, it's not a Nokia The inside so much more complicated, so I guess we just have to live with some bugs...
Are you guys sure that this is a hardware related problem? I have the same prob and i was quite sure that i f**ked up the capacitative panel by playing kevtris manickly for quite a long time.
The capacitative screen is comprised by two parts folded.
I have opened the diamond and i found out that there is a lietle piece of metal that binds them together. This was bent(from kevtris probably) so istraightened it out with my bear hands. But it did not fix the problem. Do not try it anyway. Too messy if you have two left hands like me.
Have you ever seen a calibrator for the capacitative screen?
had the same problem only the power button would work , hard reset fixed it.
Have u installed S2U2..try uninstalling it...or install latest version 1.68 of S2U2

Menu and back button.

I just bought a used hd2 yesterday, and it came with magldr with ultimate droid rom 3.3. I found out that none of the physical button acts as a Menu and Back button which makes navigation and menu access very hard. I even changed roms but still same thingn
My question is, is hd2 don't map physical keys as menu and back? Or is my unit actually defective? All the buttons work though, only that the Window and Home button does the same thing while Back and End button turns off the screen.
Thanks in advance!
Update: I have manage to get the menu (window) button working, but the back button is more trickier.. it seems thatt the physical button is actually pressing other keys.. in this case when I pressed the Window button for menu.. it will actually press the Home button which will bring me back to home screen. And for the back button, its actually pressing the End button, although I did manage to get it to press its back button, but its quite difficult. Does anyone knows how to fix this?
reply back button
I think that u may have a faulty back button or that dirt got under it thefe are guides on here xda that show u how to fix back button etc but it requires you taking phone apart and you need to read guides totally and follow steps there are also guides on youtube as well. It also sounds that the buttons might have been remapped there is an app called button remapper that allows you to change what the physical buttons do like the phone button back button etc do in other words you can change what every physical button on your hd2 does like for example the volume keys you would be able to change to back button etc. Read about button remapper on google before attempting to use app hope this helps you.
That's a common issue in the HD2, probably your device is defective.
Don't bother with the warranty, replacement and all that stuff since the back and menu aren't required for flashing or entering bootloader mode.
Just download "zMooth" app from market. (Pro version will give you End & Search)
I would prefer fixing the physical keys as they are important functions that is required in order to navigate around. Any links to how to fix the buttons? I think they are just misaligned because of prolong usage. Because multiple tries proves that it can still work.
Update: I have seen the official tutorial video for disassmbling the HD2, to just replace the keypad flex ribbon requires one to go very deep inside the phone before you can actually access the flex ribbon for the keypad. Now i am thinking twice to repair the physical button, let alone give an unofficial service guy to replace it.
@Marvlesz
I have installed zMooth, nice app.. but take some time getting used to. thanks!
or you can try a cm7 rom and use the tablet tweak soft keys in the options.
u can use button savior to replace all buttons .. it's a must have for me ..
Does anyone know if physical button problem such as mine are caused by the wear and tear of the flex cable or is it because of the plastic buttons itself?

[Q] touchscreen stops working after pressing power button

since yesterday, i have this nasty problem with my touchscreen. when i press the power button to wake the phone, or to get into the power-menu, the touchscreen stops working. this does no happen if i press any other button.
sometimes, i can use the phone again if i wait until the screen turns off and then wake it up by pressing any other button, but most of the time i need to pull out the battery and restart the phone. even when i pull out the battery, the screen won't work sometimes, and i have to restart the phone again.
when i first experienced this problem, i was using the nexushd2 v2.0 rom, i then updated to the v2.1, which didn't help. i tried reinstalling the rom, wiping the /data/ , the cache and the dalvik cache (multiple times) and eventually changed to the typhoon cm7 rom (with repartitioning and reinstalling the magldr), the problem is still there.
the phone did never get wet, fall down, or anything the like. pulling out the sd card makes no difference.
i hope someone can help me there
May be it´s a hardware problem, some HD2 have it.
You can test it, if you go back to windows.
its the good old digitizer its right under the power button press the end button hard and it should work again but if you press it again it will corrupt use softkey or remap your hardware buttons

Lol, I was about to do that
@OP, in future please use the search button before posting. There are far too many threads in this forum with exactly the same issue as Kamerius has just proved, so why couldn't you save both us and yourself some time and search first? Anyway, what you have is a digitizer issue, but a quick temporary solution is to simply press as hard as you physically can on the end call/power button. The screen should work after that. Use a button remapper or some sort of widget to enable you to use the phone without ever touching the end call button, and make sure to use other buttons to wake the screen.

i have the same problem with the endkey but with the rom in my sig
it actually has a softkey button that can be setup with a power softkey ..longpress on the softkey and it pulls up the power menu
just like it would do if you used the hardware power button
Yeah I thought there were softkey power buttons but I wasn't sure and I'm on my phone so couldn't be arsed to search

I am facing the same issue except no matter how hard I press the red button....LCD doesn't works. I have even replaced the thin metal strip which rests under hardware buttons.
Anyone?
Exactly, the same issue started to happen yesterday!!!

NEED HELP. Power button stuck.

My power button gets stuck and as you know when you long press it it reboots the phone. So basically my phone is just constantly rebooting and rebooting, its practically unusable. I need help if anyone knows a way to disable the function of power button, I mean so the power button wont do any function anymore, or swap it with another button.
I had the same problem. Got the button replaced, it worked for a month or so and I started getting the random reboots again. A search on the internet reveals that this is a common problem with the S3, and I doubt they fixed the issue for the S3 neo.
1.5 years of use and my power button is broken, my volume buttons are mushy and my camera doesn't focus at all. The build quality on this phone is a joke.
You'll probably have to have your power key replaced as well. Or do what I did and remove it from the motherboard. You won't believe how flimsy the solder is. I now use the accessibility shortcut button to lock / unlock my phone. It's a hassle and it takes up screen real estate, but at least it works.

Mine stopped doing it now but I'm sure it will start again. You are right, build quality of this phone is really lame. That part on the sides that looks like metal is mostly worned off from my phone. Camera focus is crap and volume is lower than before, I can barely hear notifications. Maybe I'll remove the button too, but I'm concerned about how to boot the phone if it turns off.
You can turn on the phone by connecting the charger, immediately booting into download mode (before the battery icon comes up) and restarting from there. It's not the best solution, but at least I have a functional phone until my oneplus x arrives sometime this week
try to do this

That's actually a fantastic idea. I thought about flashing cm that has no offline charging and booting that way, but this is better solution lol.

You can try nova launcher since it has a gesture for double tap to lock screen, or maybe a 3rd party app.
use soft lock to lock screen without pressing power button
