Getting Volume Keys to Wake the Screen

[Jonathan Goldman]

I bought a Cobalt SP300 on eBay and one of its faults is that the power button on top is a little shallow and hard to push...unfortunately it's the only way to wake the screen. I really want to use the volume keys to wake up the screen. I've tried a button remapper app (didn't work correctly) and tried an app called No Lock which disables the lock screen and allows you to wake the screen with the volume keys. The problem with it is that it only works like 10% of the time and I like the lock screen as well.

I think my only other option at this point is to manually try to edit the files. I found out how to root my phone and then through root explorer went to system/usr/keylayout and there is a file I think maps the buttons: mt6575-kpd.kl

I find

key 115 VOLUME_UP WAKE_DROPPED
key 114 VOLUME_DOWN WAKE_DROPPED
key 113 MUTE WAKE_DROPPED
key 112 POWER WAKE

So I see the volume keys say WAKE_DROPPED instead of just wake. According to a search I did by what the dropped part means, it should still wake the screen but it doesn't. Would it be sensible to edit these to only wake? Do I chance bricking my phone doing this? I tried to backup my phone using MTKDroidTools but I can't get the backup function to work...

If you mess up the button remapping you could make this issue worse, so I wouldn't suggest that. If you can root you can install a custom ROM that allows you to use the volume rockers to wake the device. I'm not sure that there is any other way to do it.

Magnus has a much better idea than remapping. I have come across a couple threads where remapping messes the phone up.

You could try this app, which doesn't seem to require root.
