I built this guide for the VW GS3 but I have to assume its extremely close for the Sprint varient as well.

The lockscreen torch will allow you to quickly turn on your flashlight from the lockscreen. Simply hold the home button in for torch, let it go and it will turn off. It is meant to function this way so you dont accidentally turn it on in your pocket or something and forget about it. Not sure who originally wrote the MOD but I have spent some time re-writing it to fit the GS3 based on a dozen or so other tutorials.

After reboot, it will take about 20 seconds before the MOD will engage. Then it will work at will as long as you are on the lockscreen.

I will include the three files that are being modified in the zip below so you can use them in your compare tool.

DEVs if you want to use this in your ROM feel free, just shoot me some credit and some thanks!

Here is the guide.....



First you will need to download the torch file below and drop it in /system/app. This will be in the zip file with the smali files.

We will be working with three smali files inside of android.policy.jar.

Navigate to smali/com/android/internal/policy/impl/KeyguardViewMediator$2.smali

Find the following code and add the part in RED
Code: 
    packed-switch v2, :pswitch_data_0

    .line 1172
    :goto_0
   [COLOR="Red"][B] :pswitch_0
[/B][/COLOR]    return-void

Find the 13 : pswitch_ lines and increase them by 1. For example
Code: 
:pswitch_0 becomes :pswitch_1
:pswitch_1 becomes :pswitch_2
:pswitch_2 becomes :pswitch_3
:pswitch_3 becomes :pswitch_4
:pswitch_4 becomes :pswitch_5
:pswitch_5 becomes :pswitch_6
:pswitch_6 becomes :pswitch_7
:pswitch_7 becomes :pswitch_8
:pswitch_8 becomes :pswitch_9
:pswitch_9 becomes :pswitch_a
:pswitch_a becomes :pswitch_b
:pswitch_b becomes :pswitch_c
:pswitch_c becomes :pswitch_d

Find the following code
Code: 
invoke-static {v0}, Lcom/android/internal/policy/impl/KeyguardViewMediator;->access$300(Lcom/android/internal/policy/impl/KeyguardViewMediator;)V

    .line 1169
    monitor-exit v1

    goto :goto_0

Add the following directly after
Code: 
.line 974
    :pswitch_e
    iget-object v2, p0, Lcom/android/internal/policy/impl/KeyguardViewMediator$2;->this$0:Lcom/android/internal/policy/impl/KeyguardViewMediator;

    iget v3, p1, Landroid/os/Message;->arg1:I

    if-eqz v3, :cond_2

    move v3, v0

    :goto_3
    #calls: Lcom/android/internal/policy/impl/KeyguardViewMediator;->handleSetTorch(Z)V
    invoke-static {v2, v3}, Lcom/android/internal/policy/impl/KeyguardViewMediator;->access$1900(Lcom/android/internal/policy/impl/KeyguardViewMediator;Z)V

    goto :goto_0

    :cond_2
    move v3, v1

    goto :goto_3

Find the "nop' at the end and add another one right below it
Code: 
throw v0

    .line 1129
    nop

    nop

Find the stack of : pswitch_ lines at the end of the smali and delete : pswitch_0
Then add the following so the entire stack will end up looking like this
Code: 
.packed-switch 0x1

        :pswitch_1
        :pswitch_2
        :pswitch_3
        :pswitch_4
        :pswitch_5
        :pswitch_6
        :pswitch_7
        :pswitch_8
        :pswitch_9
        :pswitch_a
        :pswitch_b
        :pswitch_c
        :pswitch_d
        :pswitch_0
        :pswitch_0
        :pswitch_0
        :pswitch_0
        :pswitch_0
        :pswitch_0
        :pswitch_e
    .end packed-switch
.end method

Thats it for KeyguardViewMediator$2.smali. Save and close the file.

Thats it for KeyguardViewMediator.smali. Save the file and close.

Navigate to smali/com/android/internal/policy/impl/PhoneWindowManager.smali

Find the following code
Code: 
const/16 v41, 0x3

    move/from16 v0, v22

    move/from16 v1, v41

Change the next line to the following
Code: 
if-ne v0, v1, :cond_2b

Find the following code
Code: 
invoke-static/range {v41 .. v42}, Landroid/util/safelog/Log;->i(Ljava/lang/String;Ljava/lang/String;)I

    goto :goto_a

    :cond_20

Change the next line to the following
Code: 
if-eqz v4, :cond_26

Find the following code
Code: 
const/16 v41, 0x7d9

    move/from16 v0, v38

    move/from16 v1, v41

Change the next line to the following
Code: 
if-ne v0, v1, :cond_23

Directly after that last change in code, add the following
Code: 
:cond_21
    move-object/from16 v0, p0

    iget-object v0, v0, Lcom/android/internal/policy/impl/PhoneWindowManager;->mKeyguardMediator:Lcom/android/internal/policy/impl/KeyguardViewMediator;

    move-object/from16 v41, v0

    invoke-virtual/range {v41 .. v41}, Lcom/android/internal/policy/impl/KeyguardViewMediator;->isShowingAndNotHidden()Z

    move-result v41

    if-eqz v41, :cond_22

    .line 1275
    move-object/from16 v0, p0

    iget-object v0, v0, Lcom/android/internal/policy/impl/PhoneWindowManager;->mKeyguardMediator:Lcom/android/internal/policy/impl/KeyguardViewMediator;

    move-object/from16 v41, v0

    move-object/from16 v0, v41

    move v1, v8

    invoke-virtual {v0, v1}, Lcom/android/internal/policy/impl/KeyguardViewMediator;->setTorch(Z)V

    .line 1276
    rem-int/lit8 v41, v31, 0xf

    if-nez v41, :cond_22

    .line 1277
    move-object/from16 v0, p0

    iget-object v0, v0, Lcom/android/internal/policy/impl/PhoneWindowManager;->mKeyguardMediator:Lcom/android/internal/policy/impl/KeyguardViewMediator;

    move-object/from16 v41, v0

    invoke-virtual/range {v41 .. v41}, Lcom/android/internal/policy/impl/KeyguardViewMediator;->pokeWakelock()V

    :cond_22

Here is a sort of tricky part. Starting right after the above code change you need to comb the rest of this entire method for all references to ":cond_X" and increment them by one. THERE ARE A LOT! Take your time and find them all. For example

Code: 
:cond_23 becomes :cond_24
:cond_29 becomes :cond_2a
:cond_3f becomes :cond_40
....etc.  MAKE SURE YOU FIND THEM ALL!  The last one you change should be :cond_47.

[/hide]

Thats it. Save all fines, recompile and push to /system/framework.

Enjoy and hit the Thanks Button!

Turn off the code in your settings or just know that the smilies are semicolons followed by a lower case P.

This is not a flashable zip. It's just the files needed to compare and build the mod. It will work with JB and modifying the code I have attached a little.

Hope to see this on all roms soon... I love this feature on MIUI and would love to see it on TW
Maybe we could even get it like MIUI to where as if you press the power button with the light on it will stay on

This is probably a noob question, but I am trying to use your guide for the Samsung Note II and the android.policy.jar does not contain the smali files. I cannot find the smali files anywhere as a matter of fact. Also to push them back to framework, do I just copy them via recovery using the updater-script or do they get injected into the jar file?

PS: I opened the android.policy.jar with winrar

OK, so I got the smali files extracted. When I merge them with the android.policy.jar from note II, i get the optimizing apps screen followed by a reboot. I suspect the smali files in your ZIP may be specific to GS3.

Question: If I follow the guide to make the changes to the smali files directly from the Note II's android.policy.jar instead of using your files to merge, should that work or are these changes specific to the GS3?

Thanks!

You can not just make the changes as is directly to the Note or merge it. You can follow the guide to port it to your device but the registers are not the same e.g. iput-boolean v10, p0, could be iput-boolean v7, p0, on your device. Assuming you already know that and how to fix it and are on TW Jellybean this guide should help you port. :good:

After getting into this a little it's way above my head. There are too many differences between Verizon and Sprint. I get a little lost. Lol

Thanks CNexus. Hey Didact74, do you think you can hook me up with the changes for MD4? I'd like to diff what I have so I can learn a little more about what I'm doing. Thanks.

    Here is the guide.....



    First you will need to download the torch file below and drop it in /system/app. This will be in the zip file with the smali files.

    We will be working with three smali files inside of android.policy.jar.

    Navigate to smali/com/android/internal/policy/impl/KeyguardViewMediator$2.smali

    Find the following code and add the part in RED
    Code: 
        packed-switch v2, :pswitch_data_0

    Find the 13 : pswitch_ lines and increase them by 1. For example
    Code: 
    :pswitch_0 becomes :pswitch_1
:pswitch_1 becomes :pswitch_2
:pswitch_2 becomes :pswitch_3
:pswitch_3 becomes :pswitch_4
:pswitch_4 becomes :pswitch_5
:pswitch_5 becomes :pswitch_6
:pswitch_6 becomes :pswitch_7
:pswitch_7 becomes :pswitch_8
:pswitch_8 becomes :pswitch_9
:pswitch_9 becomes :pswitch_a
:pswitch_a becomes :pswitch_b
:pswitch_b becomes :pswitch_c
:pswitch_c becomes :pswitch_d

    Find the following code
    Code:

    goto :goto_0

    Add the following directly after
    Code:

    goto :goto_0

    :cond_2
    move v3, v1

    goto :goto_3

    Find the "nop' at the end and add another one right below it
    Code: 
    throw v0

    .line 1129
    nop

    nop

    Find the stack of : pswitch_ lines at the end of the smali and delete : pswitch_0
    Then add the following so the entire stack will end up looking like this
    Code: 
    .packed-switch 0x1

        :pswitch_1
        :pswitch_2
        :pswitch_3

    :cond_22

    Here is a sort of tricky part. Starting right after the above code change you need to comb the rest of this entire method for all references to ":cond_X" and increment them by one. THERE ARE A LOT! Take your time and find them all. For example

    Code: 
    :cond_23 becomes :cond_24
:cond_29 becomes :cond_2a
:cond_3f becomes :cond_40
....etc.  MAKE SURE YOU FIND THEM ALL!  The last one you change should be :cond_47.

    [/hide]

    Thats it. Save all fines, recompile and push to /system/framework.

    Enjoy and hit the Thanks Button!

    The new torch mod incorporates the already existing logic and settings built into the rom. There are a few missing pieces on md4 but me7 is ready to go out of the box. Im out of town for a long weekend. I will post up some help when I get back.

    OK, so I got the smali files extracted. When I merge them with the android.policy.jar from note II, i get the optimizing apps screen followed by a reboot. I suspect the smali files in your ZIP may be specific to GS3.

    Question: If I follow the guide to make the changes to the smali files directly from the Note II's android.policy.jar instead of using your files to merge, should that work or are these changes specific to the GS3?

    Thanks!

    You can not just make the changes as is directly to the Note or merge it. You can follow the guide to port it to your device but the registers are not the same e.g. iput-boolean v10, p0, could be iput-boolean v7, p0, on your device. Assuming you already know that and how to fix it and are on TW Jellybean this guide should help you port. :good:

    I just started this mod and on the sprint gs3 the first step is in KeyguardViewMediator$4. I will keep working on this, but I wont have much time today, just thought some people would like to know.
