Guest Morris Lee Posted October 16, 2010 Report Posted October 16, 2010 So there is something I think everyone might want to look into, well, at least I think there is enough problems for this to get its own thread. Once the touchscreen sensitivity is increased significantly to values such as 25/75, things goes pretty wild where some people has random touches. I myself has been experiencing the same problem, and this is what it came down to: 1. someone reported that using a screen protector allowed them to have like below 10 without random touches 2. it only happens when the phone is used for a while, this lead me to think, 3. that it is the screen getting dirty, cleaning it seems to have positive results What are your workaround to this issue? Please share :) Morris Lee
Guest Rufy93 Posted October 16, 2010 Report Posted October 16, 2010 Before screen protector, I could use 8 or 9 before the screen scruwed up. Now i think i can use 7. Use ADB and run the script, (if not installed on the rom, just browse to the directory on the memorycard, and write, 'sh sens.sh' sens.sh being the script name. )
Guest dennerjw Posted October 19, 2010 Report Posted October 19, 2010 Set the sensitivity and noise to both 1 and become frustrated when your screen becomes useless. Yes, I was curious. Also not near a pc so i could use adb. Ended up having to reflash LCR-F to get a working phone again. Restoring 70 apps with Titanium is tedious.

How do you get a total number for apps you installed and the total number of apps?
Guest dennerjw Posted October 19, 2010 Report Posted October 19, 2010 Whoh! 70 apps? How do you get a total number for apps you installed and the total number of apps? When you do a batch restore in titanium backup it tells you how many apps there are, but you still have to click install for all of em
Guest Morris Lee Posted October 20, 2010 Report Posted October 20, 2010 When you do a batch restore in titanium backup it tells you how many apps there are, but you still have to click install for all of em Is there an app counter in the os? Pretty useless but nice to know : D
Guest cbtendo Posted October 23, 2010 Report Posted October 23, 2010 hi.. :P currently, im experiencing this very annoying random touch problem... my current setting is 20/50.... however, in my case, this only happened when my phone temp reached 37.5 and above.... and, strangely, this problem stops when my phone temp reached 39.7 and above... in short, this problem only occured if my phone temp is around 37.5-39.7 C... so i'm thinking that this might be some kind of hardware problem... does the same thing happened to you?

I smart guess is due to thermionic emission from the internals of the phone. I realized this at first, but I don't think it's affected due to it.

Guest Delnar_Ersike Posted October 23, 2010 Report Posted October 23, 2010 errr.... what?? :P would you explain that in idiot's term? i still doesn't get it after reading wikipedia.... AFAIK, thermionic emissions are the movements of charged particles caused by temperature. Basically, after reaching a certain temperature, charged particles are able to move off the conductor because the energy caused by the temperature becomes greater than the energy that restrains the particle to its conductor. I'm no electrical engineer, however, so feel free to correct me if I'm wrong.

I'm no electrical engineer, however, so feel free to correct me if I'm wrong. Partially it is :P Thermionic emission is the emission of electrons from a metal surface after a certain temperature due to gaining of kinetic energy from heat Since capacitive touch screens are doped semiconductors, I think that the internals of the phone actually emitted electrons to the inside of the capacitive touch screen Screen protectors didn't help me at all, it still moves. Another guess would be the background radiation (noise), which is weird because it happens even when I'm on my bed, in the cafe, etc. Edited October 24, 2010 by Koki1337
Guest Morris Lee Posted October 26, 2010 Report Posted October 26, 2010 So I am thinking is the a type of material that cancels/blocks the electrons? Put a layer in the back of the lcd and block them!!

Crazy idea to put something there though. What/how do you wanna put in? Might interfere with the heat distribution
Guest Morris Lee Posted October 27, 2010 Report Posted October 27, 2010 Crazy idea to put something there though. What/how do you wanna put in? Might interfere with the heat distribution I don't think it will be too bad
Guest Koki1337 Posted October 27, 2010 Report Posted October 27, 2010 I don't think it will be too bad Might harm the device... I found out that one the LCR-F (on the Liquid E with the bin file that LCR-F is based on) while I'm dragging down the scroll bar on contacts, somehow the notification bar jumps. By the way another theory is did you guys try setting sensitivity to about 50 and noise to 10? Since low/small numbers means higher sensitivity, does high noise sensitivity means it detects more noise to be cancelled out??? Just my guess, correct me if there's a misconception.
Guest Morris Lee Posted November 1, 2010 Report Posted November 1, 2010 So I was looking for a material that might beable to block the static from the internal components, I thought of ati static bag. It does block the sensitivity when it was above the screen at 75/75, but at 20/50, it is actually creating a negative effect
Guest Koki1337 Posted November 1, 2010 Report Posted November 1, 2010 Set the noise to 25 and sensitivity at 50?? 50/25
