[APP][ROOT] OnePlusTouchFix - Configurable vibration

ejacsve · Jul 8, 2015

This app has been heavily inspired by SabrWolfs [APP][ROOT] Touch screen fixer.

The app is supposed to at least temporarily improve the touch on the Oneplus one, making the device usable. I can't guarantee that it works for you, but it makes a big difference for me.

The app requires root, and executes the shell command cat /sys/class/input/input0/baseline_test every time the screen is turned on. It is not based on Tasker, but implemented as an ordinary app. The difference compared to Touch screen fixer, and the reason I made this app, is that the vibration is configurable. I initially implemented this app to be able to deactivate the vibration entirely, but since it actually takes a second or two to run the command and get touch working again, I found that I actually prefer a very brief vibration as feedback that the device is ready for use.

As usual with root apps, don’t forget to grant the app root access the first time it is started, otherwise it won’t work.

And as always, I can't take any responsibility if this app makes your house to burn down, your car to explode or your phone to overheat

Here is the complete code:

It was not really intended to be shared, so be gentle

Allot of users have been helped by flashing a different ROM, so it's kind of ROM related I guess.

Therefor it might be best to tell people which ROM you are using.

I'm using stock 12.0-YNG1TAS2I3, the latest offical CyanogenMod release. But, the same problem existed before as well, so it is not directly related to a specific ROM.

102 downloads and not a single reply or thank you..
I can't give any feedback,i never had any problems with my touchscreen.
But Thanx for posting your work and apparently your app works as intended or there would have been a S...storm.

Yes, this must be the first bug free app ever

Could anybody explain why cat-ting a file (i.e. just read a file content) can fix some issue?
May I see the source code of this apk?

Though i had some problem in cyanogenmod nightlies so reverted back to stock oxygenated n os

The relevant part really just looks like this

Code:

    public static int runTouchFixCommand()
    {
        int result = -1;
        try {
            Process p = Runtime.getRuntime().exec(new String[]{"su","-c","cat /sys/class/input/input0/baseline_test"});
            result = p.waitFor();
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
        return result;
    }

The key here is that it is the /sys folder. It is not an ordinary filesystem but a virtual one used to communicate with different attached devices, in this case the synaptic touch driver.
See wikipedia for some further details: https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard#FHS_compliance

If I understand things correctly, reading baseline_test will run this code:
https://github.com/CyanogenMod/andr...s/input/touchscreen/synaptics_dsx_i2c.c#L1780
Which near the end does this "//step 5:reset touchpanel and reconfig the device".

Or it may just be magic

Definitely works very well. I was using SabrWolf fix before this, thanks for the additional vibration duration option.

Unfortunately this app seems to be needed for CM12.1 as well. Fortunately it still works

I haven't tested any CAF build (perhaps I should), but in the sultanxda case, I would guess this line in the description is to blame "Rewrote half of the Synaptics touchscreen driver (over 2500 lines of code modified; your touchscreen might work better)". The function my small app relies on (synaptics_rmi4_baseline_data in synaptics_dsx_i2c.c) is removed. So I'm afraid I can't get it to work there.

I have worked a bit with xposed, but I don't really see any gain to use it for this purpose..?

I have tried Sultans CM12 version, with the CAF kernel now, and my phone is working better then it ever have. No problem with the touch, so no need for this app, at least not for me.
