[Abandoned]Home Button Lagfix & Haptic fix for Hellraised ROMs

---

After all this framework hack does not work well under too many ROMs and causes lots of confusion about version. I accidentally found a universal solution to Home Button vibration that works with JKay theme and won't break anything. So this method is abandoned.Hi everyone. I have been Hellraising i9100 ROMs since Entropy's release, however was puzzled by the Home button which lags and won't give any feeling of touch when pressed.

After some research I finally figured out how to fix this. I made 2 versions, one for XXKI3 and another for XXKI4

Currently ROMs incorporates JKay theme mods (Sensation) are not working.
(Sorry I was too excited to notice I compiled both file from custom ROMs that were containning extended power menu, the fix is not universal and try at your own risk!).

Installtion Instructions:
1. Place the zip file into your Internal SD
2. Reboot into Recovery and select "install zip from sdcard"
3. Select "install from SD card", choose YES
4. hit return and reboot

You should have haptic feedback on Home now, also the Home button should respond instantly.

Caution:
Only apply to ROMs that are based on supported Samsung builds.
android.policy.jar varies from build to build so can not hybrid with different versions.

DesignGears - home button haptic fix code reference

Ande definitely Entropy512, for the awesomeness of Hellraiser!

Please let me know if anything happens.

Currently not working with JKay themes.

For i9100XXKI3 based ROMs:

For i9100XXKI4 based ROMs:
This file is modified from an i9100 ROM with extended power menu and header, might not work if the menu had the header removed!

Thanks.... can you please post what code is changed within it (FOR HOME HAPTIC FEEDBACK) so I can mod the one for the rom I'm using. I don't want to use a generic one.
Thanks!

EDIT: Its rom specific.....you can't do generic addons.... It broke my rom which is why posting the actual change would be best. It booted but broke JKAY mods

I think KI4 version works for checkROM. However just forget I modified both from custom ROMs so does not work universally...

There are multiple places in smali that needs to edit. So you might want to compare your original file with the attachment.
It's <decompiled dex folder>\com\android\internal\policy\impl\PhoneWind owManager.smali
PhoneWindowManager.zip

I've been doing that but there are so many differences that I can't tell which is which.
Can't you just say which lines were changed....?

Line 3841 to 4568... actually works just override all differences.

Like what kind of error you are encountering? During recompile or during testing?

I don't have time to poke at this (busy sobering up after a party...) but: I suggest providing the modded version,a nd the original, and diffing them.

Note that according to Mikey, designgears' patch accidentally caught a bunch of changes that weren't related to home-button.

And yes, just copying the smali will cause an epicfail most likely, ESPECIALLY if targeting a JKay theme, as JKay did dome significant mods to that smali file.

FYI, shoman94, you've gotten as far as I ever did - I never got a working mod, but I've been pretty busy this week.

Thanks for pointing out, I recalled many other other modifications to the android.policy.jar after I posted but I cannot edit the title of thread now...

When comparing the 2 smali files (Original and DesignGear modified), except the lines for home button I only saw difference in conditions, which I don't really understand. It was a experiment that I just copyed the whole PhoneWindowManager.smali then compiled. The compiled file worked.

The file I posted is from a KI4 ROM with extended power menu with header, however since header modification is in GlobalActions.smali I think this should not affect compiling.

Tell me if I got anything wrong, first time looking into the bytecodes

Will be very thankful if you have time to look at this
