little bug in Nexus 4 with TalkBack 3.4.0 need investigate #294

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Phone: LG Nexus 4
OS: Android 4.2.2
TB: 3.4.0

Note1: This bug does not happen in the 3.2.1 version of TalkBack which is the 
default built for my phone.

Note2: This bug also does not happen to my Galaxy Grand with Android 4.2.2 on 
board.

Note3: This problem does not happen when I disable TalkBack.

Starting from TalkBack with the screen lock tone, eatch time I press the power 
key to lock/unlock the phone, sometimes it will perform a double press. e.g. 
when my phone is lock, I press the power key to unlock, it will unlock and 
quickly it will re-lock again. Same goes to the time when I finish using the 
phone, I press the power key to lock, it will first lock and very quick un-lock 
again and shown the slide to un-lock screen.

Other time, I try to press the power key to un-lock the phone, it has no 
respond and I have to press it twice only the phone wake up.

As I wrote above, this problem does not happen when I un-install the TalkBack 
update and revert to the ROM version which is v3.2.1.

I am currenly using v3.2.1 because I don't want to damage my phone hardware 
power key.

Please investigate this issue.

Thank you.

TalkBack does not take control over the keyguard/lockscreen in any way.  This 
sounds to me like either a ROM/device manufacturer bug in a custom lockscreen 
or a debounce hardware issue in the physical power button.
