[Q] About multi-touch BUG on CM7 - G2 and Desire Z Q&A, Help & Troubleshooting

I use CM7.2 on my Desire Z, yesterday I found a multi-touch bug:
when I locked screen then unlocked screen, multi-touch will not work properly short term. I have used Multitouch Test (or other apps like this ) to find out that the app cannot display 4 circles at the same time, only slide smoothly with two or three fingers, if I use 4 fingers to slide on the screen ,It will be out of control. I click on the screen use 4 fingers, try several times ,then it will work well.
CM7.2 stable, several the lastest nightlies will appear this problem. but Sense 2.1 and 3.5 can't like this, so I don't think it's a hardware problem.
PS: My English is not good, Can you understand what I mean Please help me to analyze this problem. Thank you very much!!!:laugh:

[Q] Touch delay

Hi,
is there anything you can do to fix the touch "delay" and make it more like the ipod/iphone/WM7 touch experience? I would love it but with my DHD Revolution the action is ca. 0.25 sec delayed and that sucks a bit. Will Android 2.3 fix it or is the problem just HTC Sense?

1. you can try "spare parts" from the market.
2. change kernel

what touch delay lol
i dont know if its only on my DHD (but i dont think so).
There is a little delay for me so its not like the experience on an iphone
(the only thing that i think is better on iphones) but i cant really believe that its impossible to fix it.
@Tomrec
1. Spare parts doesnt seem to work
2. as i said im using DHD revolution and i think it has one of the best kernels
but thanks for your answer
same as this problem after install RDHD touch screen less than sensitivity, and to day
i try to touch galaxy tab it smooth and fast more than htc desire hd ...Why?
do no what to say...i have not experienced any touch delay (except maybe few seconds after reboot and after i just flash it something ) and i am also using Android revolution...but i didn't have any delay when i was on stock Rom either....but i read on some post that some guys experienced some lag with revolution rom and switched to Leedroid and everything was fine.
in my (very humble) opinion...try to reflash Revolution rom (ofcourse, first, CWM backup, Titanium back up), wipe data and Delvik cache, and see how "how smooth is after that"...if not ...switch to Leedroid
Thanks for your answer i'll try it
still got the delay after wiping and flashing leedroid ...
@teerapong have you ever used WM7 or iphone?
There isnt any delay.
You can recognize the delay when you are in the menu and are sliding fast
with your finger over the screen. Then you see that it takes
a bit that the point where you started to slide with reaches your
finger again(delay).
Buggy digitizer perhaps.. never had any delay though.. The only delay that i had was at the first boot up, after that, buttery smooth, in Cm7 as well as miui.. never tried leedroid or ar hd..

Trackpad sensitivity

Hello there!
I've been using my Desire Z for a long time but found the trackpad pretty useless. This is because i found the sensitivity for it pretty low so if i want to scroll down on a page it's taking forever. I also noticed if i scroll using a piece of cloth (like my shirt) the scrolling is alot faster and usable. But it's not that nice using cloth all the time.
My girlfriend has just got an new phone the Samsung Galaxy Y Pro. It also has an optical trackpad which is alot faster and usable. Also in the settings there is an option to make the trackpad faster more sensitive.
Is there any kind of application or modification to make the trackpad faster sensitiver or so?
Please let me now .
Regards
Edit: whoops i forgot to add [Q] in the topics name and i have no idea how to edit this.
Finally a topic regarding this issue!
I noticed that using certain (mostly newer, modded - CM7 for example) ROMs, the trackpad responsivess is great.
However, recently I flashed to modded stock ROM (Virtuous G-Lite) and I also find the trackpad quite useless :/
Been searching the internet for reason or solution, but found nothing
Hope to find the answer!
So if the sensitivity differs in different ROMS it's editable in a file or so. So i think it would be possible for an smart developer to create an app that edit's the values in the file to change the sensitivity with a nice slider as GUI.
Hopes it will be there someday .
I could not agree more about the trackpad, it makes me want the responsiveness of my old G1 with the trackball (but that design is prone to fail because moisture/foreign objects can easily get underneath the ball).
Would love to see some sort of customization for trackpad sensitivity become mainstream for custom roms.
I've experienced the same problem with the following ROMs:
CM 7.1.0 Stable
Virtuous v2.0.0
Virtuous G-Lite 1.6
So it's happening on AOSP and Sense based ROMs.
Just flashed G2-Slim 1.2 (see my sig for link), which seems to be the same AOSP ROM as Virtuous G-lite, but the sensitivity responsiviness seems much better.
I have no idea how the hell can it be different..
Maybe different kernels affect this?
I'm also using the G-slim ROM for a couple of days now and besides I really like the ROM the trackpad is indeed faster. But still not as fast as I would like. Let's hope some dev. Check this thread out an can help us what makes the difference in sensitivity for the trackpad!
I remember before back on android 2.2 when using the trackpad through texts depending on how fast I swiped would determine how many letters or words it would move. But now especially with roms like cm7 no matter what it'll only move over 1 letter =/ a setting to adjust sensitivity in future roms would be amazing

That's exactly my problem! I don't want to move one letter if i like to i want to move 5 letters or scroll (fast) to the beginning with the trackpad. Just like it is on blackberry's or on the Samsung Galaxy Y PRO. My girlfriend get's the galaxy y pro on her birthday (27th of December) it runs gingerbread stock and has got an sensitivity option in the settings. Maybe i can break that functionality and put it in our phones. I don't know if it will work tho because the trackpad maybe differs. Still hoping a developer will look at this thread and help us out!

MIUI.us 2.8.31

Does anybody use MIUI.us 2.8.31 ROM?
The ROM IS working To your phone good?
I flashed (MIUI.us 2.8.31.) to my phone yesterday. Earlier I used a MIUI.us 2.8.10
I’ve found some bugs:
• Usually I’ve got a black screen after unlock,
• The soft keys (home, menu, back, search) doesn’t light,
• I use a HTC headset. The headsets bottoms don’t function. I can’t pick up the phone.
Earlier ROM (2.8.10) doesn’t was these bugs.
Other: How can I use the FM radio. It’s doesn’t work any MIUI ROM for me?
Please help me!
Thanks:
Lacika888
Sorry for my English.
I've been using this ROM since 3 days. It looks great and it's been working well. Very smooth too. I haven't had the black screen on unlock bug at all yet, though I keep hearing about it. I do have an issue of backlight not going off after screen is locked, but that's a bug in the CM10 nightlies that this ROM uses as base. Soft keys not lighting up I confirm. They don't light up at all. I haven't tried the headset issue because my dog chewed up my headset lol.
I started with 2.8.31, so I don't know about 2.8.10. But from what I vaguely remember reading in the OP, is 2.8.10 ICS or JB? If it's ICS, then it is based on aospX by existz, which doesn't have any of these problems.

DHD proximity sensor - Summary

This topic is meant to summarize all that was written about that diabolic DHD proximity sensor.
Let's gather everything you find, and try to solve this once for all, and please let's not spam dev forum section with such talks.
Scenarios:
1) The screen doesn't dim/shuts off when making a call.
Solution: First try a great app Proximity recalibrator, which can be found here (thank the guy, he did great job):
http://forum.xda-developers.com/showthread.php?p=11312762
Also, READ the whole thread before saying it doesn't work.
2) The screen dims fine (or eith some help of above app), but DOESN'T LOCK, or it turns ON when the call is answered/randomly during the call.
Solution: NONE found.
Let's assume that you've eliminated the "faulty sensor" option by:
- cleaning the sendor with cotton wab and alcohol
- trying some really different rom, like Sense.
As far as I know, sensor works with Sense roms, and problem happens with:
- aosp cfx 4.x.x (no matter the SR version)
- jellytime
So it might be something in cm10.
Or?
Write below what you know!

Ok
Also, I think the country you bought it from (and whether it is a inspire/desire), the radio in use (and RUU) could be important factotrs.
Using a British Desire HD,
July 2012: Radio 12.69.60.29_26.17.14.11_M - AT&T Inspire 4G 3.20.502.52 (Latest)
Running CFX 4.2.2 SR15+banks gapps with no work arounds.
I have used Ice Cold sandwich, jellytime 4.1/4.2 trainwreck, CodefireX 4.1/4.2 and multiple sense Roms (2.3/4.0) in the past.
I am having NO issues (although on older release of CFX, SR8 I had some random reboots)
IDK what all the complaining is about
(I have had other issues on Alpha releases (and occasionally betas)of ROMs, but Alphas are expected to have issues.)
Great, detailed info to start from.
For me, only sense (stock gb, sabsa ICS, Viper ICS) worked fine. All JB cm10 failed, and screen just doesn't lock.
Didn't realize that radio has anything to do with sensor.
What do you mean by "country matters"?

I have also had NO issues with the proximity sensor or the screen lock during calls, no fixes or calibrations made.
I've been using only JellyTime R6.1 for about a month now as my daily driver.
My DHD was bought from England. Using it now in Israel. All other info is in my signature.
broken hardware
Is there anyone that knows where the proximity sensor is actually located in the phone?
My guess would be the motherboard flex cable... :/
So my problem is, that i've dropped my DHD, and ever since then the proximity sensor/light sensor doesn't work (it is the same sensor), and I'm pretty sure that the hardware is broken.
Lately, I have been looking into the possibility of disassembling the phone, and replacing the broken part...
But as of now, i have no idea which part the proximity sensor is actually integrated onto.
Any ideas? I watched about a dozen disassembly videos on Youtube, but not one of them mention the proximity sensor.
Thanks in advance
This seems like HTC official dissassemble video:

The model sold in different countries (if it differs, I don't know) and the radio provided in different countries will make a difference.
(Sorry for late reply)
edit: The radio controls many of the phone's functions like the wireless and the cellular. It might control or affect the proximity sensor too.

[Q] Android 4.2 and multi-touch gaming issues

Hey everyone, I just had a question, with most Jellybean 4.2 roms I've tried multi-touch has been kind of non-responsive with gaming. I've tried multiple games (Dead Space, Sandbox, Pinball, various SNES Emulators) where whenever I would put more than on finger on it and remove it, both touch points would still act as if I had my fingers on it. It seems as if it doesn't register the two touches as seperate. For example, I was playing Chrono Trigger using an emulator (Snes9ex+ and Snesoid) and in order to run you have to hold down a button and navigate with the directional pad. Whenever I would do this and remove my fingers the chracter would keep moving.
This only seems to happen on 4.2 roms (Evervolv, Mazwoz, Xenon) with any kernel (I used stock, mazwoz, and blackdome). However, Jellybean 4.1 roms seem to work just fine for the most part (Solar Flare, Dirty Unicorn/Diablo) where multi-touch was just fine no issues. There is an app to check multi-touch on the market and when I used that it registered up to 5 points for 4.2 roms and anything else such as pinch-to-zoom in the browser was alright, just seemed to be gaming.
So I was wondering, is this due to the roms or the kernels? Also, is this merely just a downside with porting 4.2 roms to the EVO or just something that hasn't been reported yet?
Thanks everyone, I really appreciate all the work you developers have done.

Well this is a question that is probably asked about twice a week,but the reason for the lag is JB is not and i stress,is not made for the EVO,just not enough memory,also ICS,so you are lucky enough to get good devs that know what their doing with touch response tweaks and such,with ICS,unfortuneately we havent had such luck with JB yet,there are a few tweaks that might help with your lag since you are a gammer.... 4cyl Turbo engine v0.2.2 w/ 150 shot NOS / RTMixManager™2

Thanks a lot for this, honestly I didn't account it to lag, I just thought it was a bug since everything else was so smooth. Also sorry if this is a common question, I searched around but didn't find anything, thanks a lot for answering though!
