One of the common complaints about the new Nexus 4 is that its touch sensitivity just doesn’t measure up to that of other phones. Users experience delays in getting the phone to recognize motion, and those used to working with more responsive phones may have to forcibly concentrate on slowing down in order to have their inputs properly recognized. As we mentioned when discussing some of the handset’s failings, it’s not necessarily a deal-breaker, but it can be quite annoying. Luckily, it looks like a software-based fix should be able to greatly improve the situation, and while it’s not perfect, this early effort is nonetheless a big improvement.
You’re going to need root, an unlocked bootloader, and BusyBox in order to install the fix, so you might want to check out our guide to the Nexus 4 Toolkit to help you get things started. Then just follow the installation instructions in the source thread, flashing the files through your custom recovery, to complete the mod.
This process directs Android to use an alternate touchscreen driver upon boot-up. Reports from users confirm a noticeable increase in sensitivity, but there do seem to be a few issues: sometimes touches are registered for longer than they should be, and you could see some lag with SwiftKey.
If you do want to try it out, there’s also a file to easily revert the changes if you decide to go back to the stock touchscreen driver. Now that we see this fix is possible, we’re hoping Google makes a similar change in a future official Nexus 4 update.
