• Added method to reverse the changes, plus change reversal procedure (credit to Lars for the idea in this http://androidforums.com/bionic-all-things-root/416537-redraw-fix-bionic.html#post3230897 post

The same tried and tested and true redraw fix works on our phones as well. Kudos to Tehsusenoh for testing this.

Prerequisites:

You must be rooted

• Apply Redraw fix
• Remove Redraw fix

Apply Redraw fix

Android Terminal Procedure:

Spoiler

• Open terminal
• type the following commands
  
  

  su
  cp /data/local.prop /data/local.prop.bak
  echo "ro.HOME_APP_ADJ=1" >> /data/local.prop
  exit

• reboot

ADB Procedure:

Spoiler

• Connect your device to your USB cable, make sure that Charge only mode is set for USB Connection:
  
  Notifications --> USB Notification --> Select Charge only
  
  
  
• From a command prompt on your computer go to the {path}/Android/android-sdk/platform-tools/ folder, where {path} is the location of the Android SDK - it may be Program Files / Program Files (x86) is you downloaded the installer, or it may just be C: / D: / etc if you downloaded the .ZIP only
  
  
  
• Run
  
  

  adb shell
  su
  cp /data/local.prop /data/local.prop.bak

NOTE: Some people will tell you that this is not a true fix, and it can have a deleterious or detrimental effect on your phone. YMMV. As always,

I am not responsible to what you do to your phone. This guide is provide as is, without any implicit nor any implied warranties or guarantees.

I confirm that this works, to an extent. All of my widgets, even Elixir, started up almost instantly on the stock launcher, versus waiting a minute for everything to engage.

I'll give it a shot. Though I really can't say I was experiencing any redraw issues to speak of.

Question: How does one undo this? I don't want to assume.

What's redraw?

 

[thatguy188]

I did it (Terminal Method) and like tehsusenoh said, things like elixir seems to load quicker but not really by a lot. I don't see really any difference after doing this.

Redraw however was never really a big thing of mine anyways, I never noticed, lol.

I suppose I should put that in as well lol...

Simple - open /data/local.prop and using a text editor, simply remove the line that was added by the guide. Again, you'll need root to be able to do it, and the methodology can be accomplished in a variety of ways - direct editing, or copy file to another device, edit, copy back, etc.

What's redraw?

Basically, it is a setting that was undocumented (I believe) in the Android OS that sets a specific value on how fast the system tries to draw out UI elements on the homescreen, if I understand it correctly. In layman's terms, it's a 'fix' for memory intensive launchers like LPP and ADW that allowed for more than 3 screens, which people would load u with widgets.

it may or may not be helpful to you. So, use at your own risk.

Yeah, it depends a lot on how many widgets you have, etc. on your homescreen. And, as always, YMMV.

I'd recommend a command right after su:
cat /data/local.prop > /data/local.prop.bak

OR

cp /data/local.prop /data/local.prop.bak

That way people can restore the prop file if need be by reversing the command:
cp /data/local.prop.bak /data/local.prop

John, after the first command I got
"No such file or directory exists". I ended up finishing the commands and rebooted. Things don't seem to have changed. But, honestly redraw isn't much of an issue with my Bionic

If you're doing Terminal John has 1 slight error in his commands.

su
cp /data/local/prop /data/local.prop.bak (Should be cp /data/local.prop /data/local.prop.bak)
echo "ro.HOME_APP_ADJ=1" >> /data/local.prop
exit

Looks like it's the same in the ADB procedure

Just realized that Lars had it correct in his post hehe

Fixed - 4 occurrences of data/local/prop changed to data/local.prop

Sorry I wasn't around recently to fix this - I had 2 tests this week an a presentation today.
