Hey guys,

The Android 4.3 update for the Nexus 4, in my opinion, has majorly improved the touch screen sensitivity of the Nexus 4, therefore I believe this mod is irrelevant. For those who still want to use it, its still here.

Hey guys,

First of all, I would like to say thanks to trter10 who made the original thread for this. Unfortunately, that thread has been abandoned by the OP and forgotten about. Therefore, I have decided to make this thread. In fact, the mod that I made, in my opinion, is much better than the one in that thread.

As many of us, Nexus 4 users, have come to realize, the device's touch screen sensitivity is way below par when it comes to today's day and age. It has been pointed out that this is due to some changes in the latest touch screen driver from Synaptics, E027. An earlier driver, E015, had much better sensitivity and therefore downgrading to it improves touch screen sensitivity significantly.

There are two ways to downgrade the driver. The first way is the easiest but it doesn't work for everybody, such as people (like me) who use custom kernels like Franco Kernel. I don't know why it doesn't work, but that's the way it is.

First Method:

What You Need:
What This Does:
  1. Puts an init.d script in the init.d folder. This script will install the E015 driver on boot.
  2. Places the driver in /system for the script to use.

Instructions:
  1. Extract Method 1.zip.
  2. Boot in to your custom recovery.
  3. Install E015-TouchDriver-Mako.zip
  4. Reboot.

Instructions to Revert:
  1. Boot in to your custom recovery.
  2. Install E015-TouchDriver-Mako-Revert.zip
  3. Reboot.

Notes:
  • After boot, your touchscreen will be unresponsive for around 30 seconds.
  • After flashing a ROM, you will need to install this zip again.
  • I am not responsible for any damage this modification may cause.
Second Method:
What You Need:
Instructions:
  1. Extract Method 2.zip.
  2. Using any android file explorer, place SynaImage.E015.bin in /sdcard.
  3. Using any android file explorer, place the E015TouchDriverDowngrade script in any location you want on your internal SD card (I placed it in /sdcard/Scripts).
  4. Go into Smanager, navigate to the E015TouchDriverDowngrade script and press on it.
  5. Select the following options: Fav, Su.
  6. Press Run.
  7. The touch screen will be disabled for the next 15-30 seconds.
  8. From now on, on every reboot you need to perform the following steps in order to downgrade the touchscreen driver:
  9. Go into Smanager, click on options -> Scripts -> E015TouchDriverDowngrade -> Run.
  10. Enjoy!


Notes:
  • After a reboot, your touchscreen will be unresponsive for around 20 seconds because the kernel is reflashing the new touch screen driver (E027).
  • After selecting Run your touch screen won't work for 15-30 seconds if it does work, the old touch driver is not being flashed.
  • I am not responsible for any damage this modification may cause.
Enjoy!

Re: [MOD] Improve Touch Screen Sensitivity
@OP what is different about your zip than the original one in the thread below. Does yours work with 4.2.2 and the original does not? Is that the main difference? If so please state that in your OP. Thanks

Re: [MOD] Improve Touch Screen Sensitivity
I noticed this after a few hours with my n4 I actually have a replacement device shipping out to me soon. Ive only have the phone for 2 days. I guess this will be fixed in Android update?
