[Q] Volume buttons and trackball issues - Nexus One Q&A, Help & Troubleshooting

I was using my phone a few hours ago, and the volume screen was on and wouldn't go away. My volume was also changing itself. That, and the unlock screen was really buggy.
I figured maybe this was an app gone awry, so I decided to reboot. Now when I reboot, it goes right to the fastboot screen, but I can't use the volume keys to move, they don't respond at all.
So can anyone provide any insights? Is this likely a hardware or software problem?
Also, if I have an unlocked bootloader (which I do) does that void the warranty?

Eventually it will stop working all together like mine has.
If you're not bootloader unlocked, then just call htc.
If you are, go ahead and either download an app of the market that will let you skip/disable the lockscreen or use a ROM with trackball wake/unlock built into it.
Also, if you power button stops working altogether, you will probably want to set your screen time out really low.
Finally, if your phone cuts off, the only way I have found to cut it back on is to plug the phone up to a USB cable and let the charging light come on, then remove the battery and as soon as the light cuts off put the battery back in and the phone will cut on.
I can't remember which on it is, either holding the volume down key or the trackball but one holding of those two will allow you boot straight into fastboot instead of hboot, because if you boot into hboot you have no way of accessing any of the other options since your power button is broke, but when you boot straight into fastboot you can at least apply a nandroid. Once I had a rom that broke adb usage and got stuck on the flash screen and I thought I was screwed until I happened to boot into fastboot, so these are just a few tips for you if it quits working altogether on you.

[Q] Hero Magically Bricked?

Well today for some reason, my hero isn't working anymore. I had not changed any settings nor flashed anything or even charged it wrong. The symptoms are that everything appears to be working except the screen. A battery pull makes it so the phone vibrates when its turned on, and the buttons at the bottom even light up when used. I think its a screen problem because if not for that, the phone would work fine. What would cause this and is there any way I can get this fixed?
I can possibly help.
Are you rooted? Do you have a custom recovery and if so what version? Is your bootloader s-off?
If your answer is no to all the above
Try holding the volume down and press the power button. Does it boot into the bootloader?
Are you stock?
If so there should be an option for recovery. Press it.
Let me know any results. I'll post more info as needed.
Yeah sorry, I am rooted with the latest amon_ra (3.5 i think) however, even if i boot up with the volume button down, the screen doesnt show anything. I am fairly certtain this is a hardware issue... I might as well just break down and pay sprint the $35
Yea its bricked then. If you can get to the bootloader we couldve fixed it.

[Q] Volume down button "stuck" /Hardware button is not stuck itself/

Hey guys, I got my Incredible S a while ago. It's a splendid phone. My dad gave it tome as a gift, he bought it from Singapore. I rooted and installed many roms over the course of having it. Up until today I was using the Revolutionary 2.3.0 rom. I was browsing a Diablo 3 app on the phone when suddenly my volume down button (without me pressing it) began to function on its own. I was like "Ok, just restart the phone, probably something bugged." After the restart nothing happened for a while until after 3 minutes its started vibrating in Vibrate mode (Displaying the volume rocker on-screen) I decided to change roms since I have some .zips laying around. I installed MIUI 2.1.16 (a fairly old version I know for certain is working) Still, the issue persisted and after another restart I cannot get past Hboot. My phone is stuck in Hboot cycling the options on its own (without entering them). All my other keys function perfectly except the media button. If anyone has experienced similar issues I'd love to hear some feedback. I've also searched other threads on here, NOTHING found so far.
Cheers,

Take the back cover off and examine the actual hardware button that sits under the rocker switch. Perhaps it is stuck in the down position. See it you can get it to pop back up.
That was the first thing I did, the key is not stuck and I can freely press it. As a last resort I can send it to a local service shop but I'd like to see if I can manage this at home first. =)
Ok, fast update: by pressing the Volume UP button while pressing the Power button I managed to boot my phone into the rom itself. Now the Volume Down button does not function at all. I'll just run it through a local service shop and see if they can fix it. I was looking to buy a new phone anyways. Might keep this one as for my other carrier's sim card. =)

Samsung Captivate Power Button Not Working . FIXED :)

If your phone's power button is in a 'pressed' state, like mine, (turns on automatically when battery is inserted), it is a hardware issue.
Here is a hassle free alternative to turn on the phone when it is in sleep mode, without relying on the power key!! Takes a minute or two only!!
1. Get 'Go launcher' from the app market (play)
2. Get 'Go Locker'
3. Now Enable Go Locker on your device. And you are done!!
When the screen goes black again, Just press the volume button, The screen wakes up!!
Using this method you don't lose the normal functionality of the volume rocker!!
I recalled that I used to have Go Locker on my phone, and that when I pressed the Volume key the screen turned on!!
At that time I found it a little annoying, But now it has turned out to be such a gift!!
* For this method to work, your phone has to be rooted.
The power button is not going to work until the hardware is repaired, I prefer to use this method, because it is a safe and quick method!!
Believe me I looked around the internet and this forum for a fix, The usual method: editing the system files on the phone, and after which the volume button cannot be used to control the volume.
For those looking for a quick fix, just follow my method!
Cheers!
There are also several roms out there that have the volume rocker wake built into the rom without making it completely useless for it intended purpose. As well as several that offer a go to sleep toggle in the notification window so you can lock your phone again.
so this is a hardware issue ? i had been using the go locker i been using but the power button is annoying cus it keep showing the power button options . and killing my battery.
only fix is samsung?
Pretty much every version of cm for cappy has volume rocker wake as an option, because of this common problem. I use app called turn off screen as well.

I had the exact same problem with my Epic Touch 4G. Thought it was the ROM, the overclock, etc. I flashed back to (almost) stock, went back to original clock speeds. I couldn't figure out what it the world was causing the issue, until it got worse. Then, I noticed that even brushing past the power button would wake the screen, and about 10 seconds later the phone would reboot.
Long story short, I bought a replacement power switch, soldered it in place, and have had zero problems since!
Several eBay sellers offer the proper replacement switch you'll need.
(They don't include the required skills to properly desolder/solder it, however. It's a tiny switch - about 4mm x 2mm x 1.5mm, and you'll need a good quality fine-tipped soldering iron.)

(Q) Screen stops responding?

So across all roms including stock and cm based my touch screen will randomly stop working and i am forced to reboot the phone via the little pin hole method unless i am missing a hardware key reset combo? Anyway the screen turns on and everything looks like it works except the fact that none of my touches register at all? How do i fix this issue? Its not a big deal when i am at home with a pin or pencil but sometimes i am away from home and cant reset it...

Well, just hold down on/off button and power up button for few seconds. You will feel a vibration. It will restart
Hold it a bit more and it will switch off with three vibrations.
I guess you should get your phone checked. It seems to me hardware problem. it could be a bug too but chances are slim!
Secondly, try clearing dalvik and cache but I am afraid it wouldnt be of help!

Volume up and power button does nothing for me at all... Also would sony even look at it if im running a custom rom with an unlocked bootloader? Doesnt that null the warranty>?

Just go on stock rom n relock your bootloader. Sony might ask and make sure you say nothing about rooting, custom rom or anything. Just it's not working well should be the answer.
Secondly, try volume down +power for few seconds when phone is on. Even try volume up+down +power for few seconds.
Make sure you hold these buttons simultaneously.
