[KERNEL] CTS Kernel [Tap2Wake]

[MohammadAG]

Requires unlocked bootloader.

Requires Sony's .681 KitKat ROM or ones based on it.

Minimal features will be added to this kernel. I'm not interested in OC or other tweaks I won't use.

Features:

• Double tap to wake
• Faux123's GPL Sound Control 3
• Philz recovery
• RIC disabled on boot

You may use @Androguide.fr's excellent Pimp my Z1 app to configure sound options.

Download:

Installation:
Either flash the zip in a recovery, or fastboot flash boot boot.img

Thanks to:

• Faux123 for his sound control module
• Androguide.fr for Pimp my Z1
• DooMLoRD for his ramdisk, I couldn't get the stock one working for some reason.

Stock, please don't quote the whole post

 

[Ahki767]

Are there any added governors or just stock ones?

Stock, anything not mentioned in OP doesn't exist.
Fixed the link, sorry. DevDB messes links up.

Thank you!

It became One tap to wake when Z1 boots but after a while DT2W works fine.
Is this CTS kernel's bug?
Here is the bugreport:

Double tap to wake

not seem to work properly

 

[noob_user_]

buggy

touchscreen unresponsive while charging......

plugging the phone when screen off and trying to double tap to unlock produces the issue,,,

Does this support using external recovery on FOTAKernel partition?

1.1 out:

• Raised delay to 700, 400 was a bit too low
• Double tap to wake responds to one finger, previously, one tap with two fingers would wake up the screen
• After boot, tapping the screen would lock the device, fixed
• Timeout is correctly reset when screen is turned off

This should fix all issues with double tap to wake

Charging isn't changed, if you have issues with the touchscreen while charging, I'd say it's a ground issue or a hardware one.
And in any case, I test the kernel with the charger plugged in.

No idea what that is, got any links?
If advanced stock kernel supports it, this does.

Thanks bro :good:
you gave me a reason to unlock the bootloader, like, now! :victory::highfive:

 

[Androguide.fr]

Awesome, thanks for the dt2wake port, all my previous attempts were unsuccessful :good:

 

[Gnubaver]

So, this is exactly the same way Sony would have coded Tap2wake if they included it?

I tried to port the Nexus 5 one a few months ago, and that didn't work either. I had to do it with custom code in the touch up event

I'm trying to add it into Pimp my Z1, I've already opened an issue for you on Github that's either your mistake or my Gradle understanding, or lack thereof.

- The touch sensor runs in LPM doze mode, so it doesn't guzzle battery.
- It's double tap to unlock

Checks out

How can I make it work even when screen has been disabled for a while? For me it only works a few seconds after screen of.
Great work!

Thanks man, I've just finished cherry-picking your tap 2 wake commits in my kernel, I'll add dt2wake control to Pimp My Z1 in a few minutes.

 

[BaCKo85]

I am with 681 and unlock bootloader . I have install the kernel , but don`t work tap to wake for me ? Why ?

 

[blakwhite]

Appreciate the effort Mohammad, it works well so far.

Edit: I spoke too soon. It doesn't work sometimes, especially after some time following the lock. But it's there and obviously will work after some revisions.
