Develop Bugs

Gesture Control (root)

I'm developing application that allows you to control tablet with gestures. Root access is needed. Currently it allows to execute following gestures: Back, Home, Show/Hide status bar
Try it out and let me know what you think. What other features or actions would be helpful?
All differences from other devices fixed. Please visit main thread.

This sounds quite awesome. Does this potentially work on all HC tablets, or just the A100 and A500?

This does not work properly. It always says "Root failed" even when I grant it Superuser permissions. The only fully working feature is the "hide status bar" option. This app still seems to have potential though.

Potentially it works on all tablets, I just need a little bit of information. It even works on my SGS2 phone when I build it with decreased SDK requirements.
Could anyone test version (updated) from first post and send me logcat?

Tested - It still does not work properly. Logcat attached.

Thanks, that explains the problem. I don't recognize multitouch properly on this device. Could you execute
from shell
su -c "getevent"
or from adb that would be
adb shell su -c "getevent"
make a few multitouch and send me output.

Added single touch option. Multitouch gestures not supported on this device at the moment.
Can anyone confirm that singletouch gestures are working on A100?

You could add a gesture to disable the backlight (turn off screen). You could also add gestures to open certain apps (like browser, etc.) and possibly make them configurable.

[MOD] Collection of do it yourself tweaks

While the development is still in its infancy here,
lets post here a bunch of do it yourself tweaks.
Feel free to post any rom tweaks you know of.
In the file /system/etc/init.qcom.post_boot.sh , find the section
case "$target" in
"msm8960" | jaguar* | M2* | m2* )
Click to expand...
Click to collapse
then modify the following value:
echo 80 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
Click to expand...
Click to collapse
This will improve the touchscreen responsiveness.
Add the following line at the end of the msm8960 section:
echo 1024 > /sys/devices/virtual/bdi/179:0/read_ahead_kb
Click to expand...
Click to collapse
This will speed up loading of apps somewhat.
Reboot for changes to take effect.

In the same file you can have it run every init.d file if you don't have init.d support.

governor tweaks
if on the on-demand governer i recommend you change the sampling rate to 70,000, it improves the devices scaling performance i.e if your device is sitting for a sec. and you touch the screen it should jump to a higher frequency to perform the action faster at the cost of a little bit higher battery consumption but a minuscule amount. And of course please all use the noop i/o scheduler it really does improve responsivness of the phone by alot.
I will aslo be uploading a sys ctl.conf tweak to greatly improve our battery life my og epic increased by 3 hours because of this it is a cwm flashable but for those who dont feel like using it you can always use a root explorer and copy and paste or adb push it. i will post when i know it works
file is migrating to new host this is the link you have to take it apart and either copy and paste or adb push, the install script is giving me trouble will post back when i get around to fixing it unless some brave soul would like to fix it for me idc its all about you guys so if you wanna beat me to it be my guest
and remember always make a nandroid
I would also like to say i did not create this and i have absolutly no idea who did this mod has been circulating around xda's htc forums,android central, and droid forums as far as im concerned the maker of this mod is untraceable.
V6supercharger makes a world of a difference in the memory management section and no ram is waisted it is devoted to the cache for our devices its a pain to set up because we are on odex stock devices ice is a bitc* that way haha.

I found this thread here with several build.prop tweaks... He claims they work on all devices. I am an Android newbie so I can not verify that information.

Another tip to save battery is enable power saving mode. It automatically scales back the cpu governor to a max speed of 1.026 ghz. Unless you're gaming, this should be fine for day to day usage.
I have tested this with cpu spy and no frills cpu control.

Its alot easier if you used an app like setcpu and go to governed setting ans change the up thresh hold to 80 remember the lower the number the higher the performance at the cost of Max battery life but never set it to 100 it freezes really badly. 99 is even a stretch u shudnt need to go over 95

How to switch off your softkey backlight

I see a few people asking about this and I found this app that works on my HTC One X.
Screen Filter:
https://play.google.com/store/apps/details?id=com.haxor&hl=en
If you just want to switch the lights off, set the filter to 100% then un-tick the enable softkey back light. It works great when watching videos or using it as a nightstand clock.
Hope their wasn't a thread about his. I did a few searches and couldn't find anything, hope this helps a few people.

Does it save the preference after reboot? I use Adjbrightness and after rebooting I have to load the app up again.

I will have a look but I think you have to reopen it.

I had a test now and it doesn't start on boot. But when you start the app after a boot it then knows what your last settings were. Hope that helps.

If u put the app (screenfilter) in some autostart program it will work fine, if u dont wanna enable it manually.

Don't worry if you hold down the power button for a couple seconds it simulates a battery pull. Then when you start up, provided you don't have it on a autostart app you can then go in and change the settings. Also if you do set the brightness too low it gives you 10 seconds to approve it or it will just revert your settings. If that makes sense.

Make a new file, call it 99KeyOff.sh and put this in it:
#!/system/bin/sh
# ========================================
# init.d script for key light off. ONE X.
#BACKFROMTHE[/QUOTE]STORM
# ========================================
#disable Key Backlight
echo begin set Key Backlight - KB
echo KB - set permissions rw
chmod 0666 /sys/class/leds/button-backlight/brightness
echo KB - set Key Backlight 0
echo "0" > /sys/class/leds/button-backlight/brightness
echo KB - set permissions ro
chmod 0444 /sys/class/leds/button-backlight/brightness
echo KB - done!
Put it in the init.d folder or run it manually in a terminal emulator or script manager.

Unfortunately that doesn't work on the Maximus ROM. I think it's because the rootfs mounts read only. I tried adding a remount line to the top but nothing happened.

[RESOLVED][IDEA/REQUEST] Backlight button light up notification

See first post, page 3 for an solution
-------------------------------
Dear XDA,
I've searched for this kinda app but couldn't find it so i decided to make a thread about it.
Anyway, i was wondering if it's possible to make the backlight of the buttons light up when there is some kind of notification as the led in the One X is kinda useless imo.(dirt gets into the tiny holes)
If it IS possible, does someone want to take the effort to try and make such an application/mod?
I'll be eager and happy to test it and my thanks will be beyond eternity
Thanks in advance,
Joran

Good idea, but I do think there could be any hardware limitations to make this work....
anyways, sounds great if it could be possible! :good:

I wrote an app called "Capacitive Button Brightness" which lets you control the brightness of the capacitive buttons backlight on the HTC One X: http://forum.xda-developers.com/showthread.php?t=2033973. Someone pointed this thread out to me so I thought I'd chime in with an idea.
I have not tested this (in fact I don't have a device to test it on!) but you might be able to flash the backlight of the capacitive buttons by running the following command from a root terminal:
Code:
echo 1 > /sys/class/leds/button-backlight/blink
If that doesn't work, take a look at the list of files in /sys/class/leds/button-backlight and see if perhaps I got the name of the file wrong. There should be one in there with "blink" in its name.
If this does indeed flash the capacitive button backlight then you could write a simple script in "Tasker" to blink the capacitive button backlight every time that a message is received.
User Vcek reported doing something very similar with Tasker, and I'd recommend to contact him if you have further questions. See http://forum.xda-developers.com/showthread.php?p=35266420#post35266420 and http://forum.xda-developers.com/showthread.php?p=35276999#post35276999

You're right, my app won't address the feature you are looking for.
If you want a terminal, you can install "Android Terminal Emulator" from the Play store: https://play.google.com/store/apps/details?id=jackpal.androidterm. You will need to be rooted though.
If you want to test out the "echo" command in the previous post, you will need to run "su" in the terminal before running the "echo" command.

[GUIDE] S4 Proximity Sensor Fix (Blank Screen During Calls)

Please note the same information used to develop the app is in the guide for free... the app just makes it easier
You can find the app here
CALIBRATION REQUIRES ROOT... PLEASE GO GET ROOT ON YOUR PHONE AND THEN COME BACK.
Oh and BTW... I cannot be held responsible for anything that happens to your phone.... EVER!
use "adb shell" or a terminal emulator to get a terminal prompt and run the following commands
Step 1. - Save old calibration value (Optional)
Code:
su
mkdir /sdcard/S4data/
cat /efs/prox_cal >> /sdcard/S4data/prox_cal
Step 2. - Edit calibration value and update permissions
Grab the current value with everything clear of the proximity sensor.
Code:
cat /sys/devices/virtual/sensors/proximity_sensor/state
The value on mine was between 45 and 55. If you a lot higher then there might be something wrong with your phone. I used 150 for my value. You can use whatever you want but 150 is working great for me.
Convert your calibration value to hex (The windows calculator works great for this... use programmer mode). Put your calibration value in place of the 96 in the command below.
Code:
su
echo -en $'\x96' > /efs/prox_cal
chown system:system /efs/prox_cal
chmod 644 /efs/prox_cal
sync
Now reboot and your proximity sensor should be working.
Big thanks to greaty for his post here

Does this app remove dirt/lint from your proximity sensor?

Sent from my Touchwiz device that never forgets gapps and everything works the way its supposed to.

I took my phone all the way apart and cleaned the sensor and it still had the issue. It seems that the sensor reads about 50 all the time and that is where they have the trip point set. This guide and the app just move that trip point.

because you dont know how to clean... i had 46 all the time and now i have 11-12 for month or two and it is not increasing anymore because i shielded it with silicone/rubber and no more dust come inside - thats the only permanent way to fix this.

I dont think its for CM11 also

I believe it's only in TouchWiz roms.
Cleaning the dirt out of the sensor is the only long term solution to fix it. But even then it's not permanent. It will eventually get dirty again.

This guide solve my problem.
I noticed about the problem when flashed AOSP based Rom. So, thinked it was a rom bug.
Then, flashed stock again and find the issue was still there.
After trying whit compressed air, and nothing changes, rooted my phone (again) and follow this guide, and proximity sensor is working again.

I'm using an AOSP ROM (http://forum.xda-developers.com/showthread.php?t=2643031) and worked for me.
But the point of my post (and I have the Verizon edition BTW) is to say THANK YOU! I got to the point where every time I made a phone call I knew almost certainly my screen wouldn't turn on and even half the time hitting the home button wouldn't do the trick. I know the issue is my otter box defender series, which never caused this problem until about a month or two ago. But I need the otter box and this fixed my problem... Thank you thank you! No more random voice mails from me because my screen won't turn on haha
Edit: For those on AOSP, if you type the value in the calculator, swipe left and hit HEX, it will give you the hexadecimal value you need

Ever since I flashed any custom ROM on my tmo S4, the proximity sensor hasn't worked right. Screen would never wake after a call ended, even the app I use to keep the screen off in my pocket (Gravity Screen, pretty cool app) wasn't working. I used the little app referenced in the OP, and it all works again! Thanks! :good: :highfive: :victory:
