Does anyone have any information about how to adjust screen sensitivity under Android, specifricaly Froyo on Nexus One?
I'm trying to research this topic but there seems to be very little information about this. I can't find any tool, script or custom rom that would allow screen sensitivity to be adjusted.
I found a thread talking about doing it for Liqid's touch using script but that's about it. I took a look on the script and I can't move forward with it as the path's script uses do not exists in my Nexus One. If anyone has any experience with this please share. The goal is to make the screen more sensitive then it is as a default.
Thanks.
Thread reference above:
android.modaco.com/content-page/309503/increase-touch-screen-sensitivity-only-tested-on-liquide-1-100-05-based-roms/page/40/
Script:
#!/system/bin/sh
sensitivity=25
noise=25
echo "set sensitivity to $sensitivity"
echo $sensitivity > /sys/devices/platform/i2c-adapter/i2c-0/0-005c/sensitivity
echo "set noise to $noise"
echo $noise > /sys/devices/platform/i2c-adapter/i2c-0/0-005c/noise
echo "done"
Sorry for bringing back something from the dead, but I've been researching about this. Nexus One screen sensitivity is low, compared to other touch screens I've experimented with. I know Nexus One is using a Synaptics board. Digging in the source code of Android, I found that the settings on the device itself are located here:
/system/usr/idc/synaptics-rmi-touchscreen.idc

# Refer to the input device calibration documentation for more details.
#
# Touch Size
touch.touchSize.calibration = pressure
# Tool Size
# Driver reports tool size as a linear width measurement summed over
# all contact points.
#
# Raw width field measures approx. 1 unit per millimeter
# of tool size on the surface where a raw width of 1 corresponds
# to about 17mm of physical size. Given that the display resolution
# is 10px per mm we obtain a scale factor of 10 pixels / unit and
# a bias of 160 pixels. In addition, the raw width represents a
# sum of all contact area so we note this fact in the calibration.
touch.toolSize.calibration = linear
touch.toolSize.linearScale = 10
touch.toolSize.linearBias = 160
touch.toolSize.isSummed = 1
# Pressure
# Driver reports signal strength as pressure.
#
# A normal thumb touch while touching the back of the device
# typically registers about 100 signal strength units although
# this value is highly variable and is sensitive to contact area,
# manner of contact and environmental conditions. We set the
# scale so that a normal touch with good signal strength will be
# reported as having a pressure somewhere in the vicinity of 1.0,
# a featherlight touch will be below 1.0 and a heavy or large touch
# will be above 1.0. We don't expect these values to be accurate.
touch.pressure.calibration = amplitude
touch.pressure.source = default
touch.pressure.scale = 0.01
# Size
touch.size.calibration = normalized
# Orientation
touch.orientation.calibration = none

Also, in the kernel, the synaptics driver can be configured to be more sensitive. It is located here on the kernel source:

Maybe we can tweak only the .icl file, or we'll have to dig deep into the kernel to improve the responsiveness of this touch screen!
Increased the sensitivity by changing the value:
touch.pressure.scale = 0.01 to touch.pressure.scale = 0.001
in /system/usr/idc/synaptics-rmi-touchscreen.idc
Please use the Q&A Forum for questions Thanks

I just tried this on my MyTouch 4G Slide (htc Doubleshot) running CyanogenMod 10 (20130101). It either works beautifully or it's my imagination. Thanks!!!!!
Screen Sensitivity Enhancement
GandalfTW said:
Does anyone have any information about how to adjust screen sensitivity under Android, specifricaly Froyo on Nexus One?
I'm trying to research this topic but there seems to be very little information about this. I can't find any tool, script or custom rom that would allow screen sensitivity to be adjusted.
I found a thread talking about doing it for Liqid's touch using script but that's about it. I took a look on the script and I can't move forward with it as the path's script uses do not exists in my Nexus One. If anyone has any experience with this please share. The goal is to make the screen more sensitive then it is as a default.
Thanks.
Thread reference above:
android.modaco.com/content-page/309503/increase-touch-screen-sensitivity-only-tested-on-liquide-1-100-05-based-roms/page/40/

The easiest way you can change your screen sensitivity is by using Screen Booster apps from Google Play. Its really works dude
So let's say I did this and now my screen doesn't work. How can I get it back?
found new method
worked for my zte v9800
Go to System and find build.prop
Then copy the bellow lines and just paste in bulid.prop
# Touch screen calibration and scroll responsiveness
debug.performance.tuning=1
windowsmgr.max_events_per_sec=200
view.touch_slop=2
view.scroll_friction=1.5
view.minimum_fling_velocity=25
ro.max.fling_velocity=12000
ro.min.fling_velocity=8000

Hi..
This is my first post & thread in XDA-Dev, pardon me if i break any rules...
Just tell what i could do to mend the situation and I'll gladly comply.
Intro
Here's what's been bugging me for the past few days.
I'm trying to recompile Sony Ericsson source code archived as x10_x10mini_X10minipro_x8_eclair_2.1.A.0.435.tar.gz to enable a few features :
Swap support
Ad-Hoc wifi
I followed the tutorial on Android Central (http://forum.androidcentral.com/htc-hero-rooting-roms-hacks/8072-how-build-your-own-kernel-package-source.html) except that I'm using SE's kernel codes rather than HTC's.
My Environment
Ubuntu 10.10 over VirtualBox over Windows 7
Using compiler in the Android Toolchain (gcc-4.4.0)
Folders Structure
~/android/source/ : Contain SE Kernel Sources
~/myandroid/ : Contain everything that you should get when you repo git://android.git.kernel.org/platform/manifest.git
Settings
hit export ARCH=arm
hit export CROSS_COMPILE=arm-eabi-
hit export PATH=$PATH:~/myandroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin
for .config, i used the one from 1.6 as latter version of SE phones does not have /proc/config.gz
What I did
First, i compiled the kernel using the default settings, it completes successfully.
I make clean
When i run make menuconfig I changed
General Setup --> [*] Support for paging of anonymous memory (swap)
System Type --> MSM Board Selection --> [ ] MSM7x27 Mimmi (deselect)
System Type --> MSM Board Selection --> [*] MSM7x27 Shakira (select)
I run make
I was thrown error below.

I did some regex on all files in the SE directory and sub-directory, looking for any mentioning of semc_gpio_event_matrix_func, there are 5 files that has it, namely...

/home/android/android/sources/kernel/include/linux/semc/gpio_event.h
Files with silver color is irrelevant, as I'm building the X8. I assume it's safe to ignore them.
my username on the ubuntu is also android, hence the .../android/android/....
Please help me troubleshoot this...
So nice to see someone dev the kernel and I`'m sorry to say I can't help but i'm interested how you wan't to flash the kernel. Isn't it locked by SE to flash a custom kerneL?
I think they give you something so you can use it.

There should be some way because SE gives us kexec tool even in retail firmware...

well if i can't load the whole kernel into the phone, at least i could push custom patched wpa_supplicant.
if it's really impossible, at this date, to use custom ROM on X8 why would then people are toying with the Floyo port?
For now, I'd be happy to just solve patching wpa_supplicant. But since I'm already into this, why not get it done with.
So now there's 3 files that are involved.
herein, are those 3 files, underneath each of which are the files that it #includes and their respective location in the filesystem.
to be honest, i was only looking to play with the config files when i started this.
i've never compiled project this big (i did, but that was looong time ago, and it went without a hitch).
for the past 2 years i only programmed Arduino on C, and occasionally PHPs. So i rarely have to deal much with header files. Also some recreational cracking utilising assembly.
there was a few other errors before this one actually. But it was easily solved by changing <xxxxxx.x> to "xxxxxx.x"
so guys please, please help me.

see anything?
I would assume any files with the word keypad are referring to the mini10 pro's slide out keyboard. Your x8 doesn't have one so try and remove from the build process.
Either way the bootloader is locked so I'm not really sure how you will push this onto the phone in the first place.
If you do succeed let us know.
Edit: gpio and wakelock events are probably directed to the hardware switch when the keyboard is opened or closed.

in board-shakira-keypad.c, the keys that it governs are the volume up/down, cameray, back, menu and home keys. nothing more, nothing less.
so i'm pretty sure it is for x8.
I'll post the content of the file later.
undefined reference to `semc_gpio_event_matrix_func'

can you just look in semc_gpio_matrix.c and add a prototype for that function into board-shakira-keypad.c if it's not provided in any of the other headers.

can you just look in semc_gpio_matrix.c and add a prototype for that function into board-shakira-keypad.c if it's not provided in any of the other headers.
Click to expand...
Click to collapse
Seems like linux/semc/gpio_event.h already declared the prototype. That's all that it does.
i think i know the culprit....
board-shakira-keypad.c calls semc/gpio_event.h to declare the prototype.
but nowhere in those two files have the function actually defined.
The only file that have the function defined, semc_gpio_matrix.c, is not called by any other file.
How come SonyEricsson release such source files? is this not the final set that they use to compile the binaries on our phones?
My question now :
is it okay if i edit board-shakira-keypad.c into something like this :
Code:
#include <linux/platform_device.h>
#include <linux/gpio_event.h>
#include <linux/semc/gpio_event.h>
[COLOR="Red"][B]#include "../../../drivers/misc/semc/gpio_matrix/semc_gpio_matrix.c"[/B][/COLOR]
#include "board-delta-keypad.h"
#include <mach/semc_rpc_server_handset.h>
#include <asm/mach-types.h>
#include <linux/gpio.h>
compilation success this way.
however should i tell the compiler/makefile to find the symbol in the object file of semc_gpio_matrix.c instead?
there's no object file in the folder that contains semc_gpio_matrix.c, except for built-in.o. What should i do?
how about putting a line on top:
extern int semc_gpio_event_matrix_func(struct gpio_event_input_devs *input_dev,
struct gpio_event_info *info, void **data, int func);
And modify the makefile to compile and link the semc_gpio_matrix.c and it object file.

if it's really impossible, at this date, to use custom ROM on X8 why would then people are toying with the Floyo port?
Click to expand...
Click to collapse
Rom <> kernel. What they're doing is all BUT the kernel. Making drivers and libraries run on SEMC supplied kernel. I don't know much about low-level on the phone, but it's not like the google dev phones. The bootloader is very different. My guess is it's more like old SEMC phones. The google dev phones boot more like a pc. This is why there's no tether support on these ROMs.
There's tools for flashing files to the device, so I guess if you're able to make compatible files you'll get the kernel in there. Maybe have a word with the creators of the x10flash tool.
Simple!!!!

So nice to see someone dev the kernel and I`'m sorry to say I can't help but i'm interested how you wan't to flash the kernel. Isn't it locked by SE to flash a custom kerneL?
Click to expand...
Click to collapse
The answer is so simple...convert the kernel to .sin, then flash it with bin4ry's flasher
Nobody has try this.
Rename sin to img make changes img to sin flash
Sent from my X8
If that was so simple then multitouch would be the first thing done to the phone... Sin files are signed and hashed, if you change them signature becomes invalid and phone won't accept the file...
Sent from my X8, so sorry for gramatical inaccuracy
i think i took the wrong approach in learning system development for android....
i think i should have started via the kitchen section to better and easier understand the low level inner working of the system..
plus, for someone that comes from the Windows world still got much to learn about how things work in Linux world.

From the error, I can tell that .val isn't declared, or something similar, but I need help from an expert to fix it.
Faced with same problem for Alcatel OT Fire E 6015X. My solution:
- Install Android NDK (ArchLinux):
Code:
pacman -S android-ndk
- Add path:
Code:
export PATH=/opt/android-ndk/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64/bin:${PATH}
- Run build:
Code:
make CROSS_COMPILE=arm-linux-androideabi- ARCH=arm zImage
need to replace every .val for .cur.val, the problem is that the val variable is declared within a union named cur inside the v4l2_ctrl structure. So in order for the Compiler to recognize it should be addressed thru the union var
Hello
I have problem with my sony xperia z2 i lost cell radio because radio is off... I don't now why but it is...
I try reinstal system many times reset all values and it don't work.. to time when i flash android 4.4..2 (or 4.4.4) and flash this i edit this flashable zip and this working but when i update to lolipop(5.1..1) radio is still off... i realize binary( radiooptions) for kitkat is difrent than lolipop. At this website is source code but i can't find compile binary to lolipop.. I be very happy if someone can compile radiooptions for lolipop or know how to repair this "bug" because after many attempt i don't now how
PS: All application to turn on cell radio don't work...
PS2: Sorry for my English...
code in case of...

First of all, hello my name is Clement I'm trying to overclock a kernel for Realme 3 pro (SDM 710)
A little background story Realme has the 3 pro and 5 pro version, although both has a gpu of Adreno 616, in realme 3 pro, the clock speed is limited too 504 Mhz while in the 5 pro version its at 610Mhz
I've tried to change the clock speed in the sdm670-gpu.dtsi but it ends up in white screen.
I changed the values under
Code:
"qcom,gpu-pwrlevels-4
/* NOM */
qcom,[email protected] {
reg = <0>;
qcom,gpu-freq = <504000000>;
qcom,bus-freq = <11>;
qcom,bus-min = <9>;
qcom,bus-max = <11>;
};
/* SVS_L1 */
qcom,[email protected] {
reg = <1>;
qcom,gpu-freq = <430000000>;
qcom,bus-freq = <11>;
qcom,bus-min = <8>;
qcom,bus-max = <11>;
};
/* SVS */
qcom,[email protected] {
reg = <2>;
qcom,gpu-freq = <355000000>;
qcom,bus-freq = <8>;
qcom,bus-min = <5>;
qcom,bus-max = <9>;
};
/* LOW SVS */
qcom,[email protected] {
reg = <3>;
qcom,gpu-freq = <267000000>;
qcom,bus-freq = <6>;
qcom,bus-min = <4>;
qcom,bus-max = <8>;
};
/* MIN SVS */
qcom,[email protected] {
reg = <4>;
qcom,gpu-freq = <180000000>;
qcom,bus-freq = <4>;
qcom,bus-min = <3>;
qcom,bus-max = <4>;
};
/* XO */
qcom,[email protected] {
reg = <5>;
qcom,gpu-freq = <0>;
qcom,bus-freq = <0>;
qcom,bus-min = <0>;
qcom,bus-max = <0>;
};
}; "
and adjusted the clock and the power levels.
even changing 1 Mhz will end up in white screen. By the way , the white screen occurs whenever I change the clock speed in the kernel manager to the overclocked clock. If its in the normal clock 504 Mhz, the phone works fine.
I've also noticed that both phones(3p and 5p) have the same exact regulator values so I think it's not a regulator issue.
Values in the driver are also changed.
Can anybody help or point out where i did wrong?
Dmesg log here:
This is the kernel source for the Realme 3 Pro and Realme 5 pro
