The Google Nexus 4 is in many ways the best Android device we’ve seen. The new flavor of Jelly Bean (Android 4.2), hardware specs, performance, and other outstanding features proves that. However, there are few complaints about this device. A most common complaint is less responsive touchscreen. If you feel a slow responsive touchscreen on your device, then there is a workaround to solve this issue.
An XDA developer Trter10 has provided a simple solution to enhance the touch responsiveness of Nexus 4. By downgrading the touch driver that senses touch better, you can improve the touch responsiveness of Nexus 4. However, you can always revert this.
The procedure to downgrade the touch driver is rather simple; however, it only works on rooted Android devices.
Important: As always, do at your own risk. We can’t take responsibility for anything that goes wrong.
– Now, download the old touchscreen driver file (get it from the source link below) and copy it to the root of your Nexus 4. Then flash it in custom recovery.
[To flash in custom recovery, Restart Nexus 4 in recovery mode – Select choose zip from SD card – select the .zip touchscreen driver – Select install]
[Rooting and flashing is really a quite straightforward process. If you don’t know how to root and flash in custom recovery, you can find a good tutorial at “forum.xda-developers.com”, for example read this]
– Once the driver installation completes, restart your device, then test its touch responsiveness. You should notice an improvement.
Now, if for some reason you want to undo the above steps, just download RevertE015 file (download available at source link), copy it to your device, and then flash in custom recovery. [Via]
