Optical joystick, trackpad - issues / low sensitivity - Desire General

Hi All,
Two weeks ago I became a quite lucky Desire user, but recently I've noticed decreasing sensitivity for optical joystick.
I have a feeling that at the begining it worked better, but right now from time to time it just stuck, non respond or just have a weird behaviour.
What I obsereved that if you will use piece of cloth (t-shirt, case - whatever with "structure" material) it works perfectly. In that case it response quickly, really nice.
Made research using diffrent "sides" of finger - and slightly better when you use side not a finger tip. Also trial on my colleguage proved that something is wrong.
Have you faced with such issues?
shall I wear gloves ? any other workaround?
is there any application to calibrate this optical pad?

Same issues =(

Got the same issues since the beginning. Actually the pad is nearly unusable for me. Strangely in the text box it works much better than other places. It's a bit annoying and there are times I wish I had a mechanic trackball like the N1...

I too have the same problems and it's been like that since I had the phone.
I just thought it was normal and never use it as it's pretty much useless!
I just tried using the edge of the t-shirt and it works PERFECT!
Miss the trackball I had on my G1... that was uber sensitive and worked perfectly.
Might bob into the three shop and see what they say.

hmm dont notice any different with shirt / edge finger or normal use o.o where are you guys testing this on test or the menu? usually one vertical swype up on the menu makes the cursor go 1 page or sometimes 1 page +1

It really works perfect with the shirt.
For example right here to switch between posts. With my finger I often need to slide multiple times over the pad til it reacts.

It's really annoying.
Just tested on switching between homescreens and scrolling through texts and I have to do it multiple times with my finger and then it doesn't always work but then work absolutely fine using my t-shirt.
Surely HTC must be aware of this problem. I have seen quite a few comments on this now.
Phil

Yeah he's right just tried with my T-shirt and it actually amazed me how useful the trackball became.
Shame my hands are not made of cloth.

I have just emailed HTC to see what they have to say about it.
Perhaps if i wore gloves all the time just in case I needed to use the trackpad... oh but then my fingers wouldn't work on the screen

Hmmm on this thread I can scroll the while page in 1-2 swipes try putting more pressure on it

Nope! Pressure makes absolutely no difference!
When I use my t-shirt I barely have to touch it to get it to go exactly where I want it to!
Definately a problem with it. Perhaps they had a dodgy batch of optical sensors!?

Hm... Maybe a guess. I know, certain people have papillary lines on their finger tips, which are rather noticeable and are really easy to identify. The others don't.
Could this be that the trackpad sensor too much relies on identification of those papillary lines, and in case they're less visible, is unable to "decipher" the moving finger?
And yes, I also can confirms that:
1) Trackpad is more sensitive in Messages app
2) Trackpad is more sensitive when flipping left-right than up-down.

The optical trackpad is like a mouse, it detects image changes, the cloth (normal t-shirt cloth) has it wires parallel both vertically and horizontally, and it's really simple for the sensor to read it (the lines going from left to right or from down to up).
Now if you move the sensor on a completely blank surface for it's resolution it won't read any movement, no matter you move it half a mile. By blank for it's resolution I mean if it is 600dpi and the material has no difference larger than 1/600 of an inch. I imagine the Desire's optical sensor is no gaming Logitech laser mouse with 1200dpi 50-100dpi at most.
Back to the finger, everybodys fingerprints are different, (CSI people thanking the nature), so the lines on your finger can help or give a hard time to the sensor, I've also had problems using it, in the browser, on a hundreds of links page like a forum, I gently move the finger, the selected link stays the same than just jumps 3 links down, over the link I want, I go back and it goes back by two, again over my link, and the third time I get it right, or use the doubletap and the touchscreen ...
Maybe somebody can find the calibration/sensitivity file for us to edit.
PS: Sorry for my English, I did my best...

I think you got it in one there!
I just tried with my finger side-ways (so the lines on my finger are going the other way) and it works perfectly. I think that must be why it works better going sideways than up and down.
Bit dissapointing really... what was wrong with having a trackball?!
P.s. Your english is very good...nothing wrong with it!

Is it just me or does this seem like a totally irrelivent solution. Surely doing a hard reset will do absolutely sweet FA to resolve an issue with a hardware related issue?!

I mean have you tried playing replica island with the trackpad!? It's impossible..

Screen locking application

Very simple and very very light application.
Does exactly what it says on the TIN.
The reason I compiled this application is purely to avoid using power button as I don’t want it to worn out. To turn the screen on or off we have to use power button which might stop working if we use the button too much. This application will cut the use of the power button by 50% at least
Rather than using the power button to turn the screen on and off, tap on this application to turn the screen off. Very small application V1.0
I might release another one when I get feedback from the users.
If you want just exe file then copy it in to your phonewindows->start menu-> program folder
Or use cab file which will install it on the above location for you
Enjoy !!!!
Trying to be contructive, the way this application could be more useful (to me) would be if it triggered the standard screen lock at the same time as switching off the screen. This would save me tapping 'start' then 'lock' and then pressing the power button.

hiya,
much appreciate for your comments. do you mean turning screen off as well as locking the screen..? so that when you touch the screen it won't come back on...?
I'm working on to prepare better version i.e. it would be on the home screen so that no clicking on start menu and then this app.
cheers

I think he means that you program should not only turn off the devise, but also lock it with the standard WM lock at the same time. That would be good for me, at least.

screen off + lock at same time only pressing Powerbutton.
It work perfectly for me so as it is. I changed the left soft-key so that it will start "turn off the light.exe" .When the screen is off S2U2 will lock the screen. So I can turn off and lock the screen with only one click.
To change the soft key do this:
with a registry editor go to HKLM/Software/HTC/manila/ . in HomeLSKPath (left softkey) or HomeRSKPath (right softkey) write the address to "turn off the light.exe". HomeLSKText and HomeRSKText are the text for the softkeys.
That´s it!
update for touch diamond
hi everyone,
massive thanks to all those who provided replies. I have tried on my blackstone (Touch HD) and it does seems to turn off the screen plus all keys as well.
I can confirm that it doesnt lock all the keys i.e. doesnt lock the device on touch diamond model. I'll modify the program and upload the newer version with the feature of locking the keys plus turning off the screen.
once agian special thanks to everyone.
Certainly reading the comments above, people seemed to understand what I was getting at. With the screen off, the buttons on a HD will indeed be non-responsive, however if an event (SMS or similar) woke the screen, the device would be in an unlocked state. What I would be interested in is a program that turned off the screen and invoked the standard WM lock program (gwes.exe?).
Hope that makes sense.
i like this application but i think the icon is really ugly..
Hi,
is there a possibility to do a screen unlock application which can be activated by voice commander? the situation is this...
I used voice commander to launch google maps while my hand is busy when the screen is lock. however, i will need a program which can be initiated by the voice commander to unlock the screen so that i can navigate the maps. Right now i will have to unlock the screen the normal way which i find voice commander redundant since i'll have to use my finger during lunching anyway.
Can you help me on this? Many thanks in advance. =)

Thanks for the link!
Been using this app so i dont have to fumble with the power button to turn the screen off. Seems this app only turns off the screen and doesnt actualy put the phone in sleep. I would like an app like this that acts as the power button does. So when i put the phone to sleep with the icon, i cant accidently slide the keyboard out a touch and have the phone wake up.
The whole deal has to do with tilt 2's keyboard sensor and magnet cases. With this app, the keyboard sensor still activates when sliding into a magnet flap case, while having slie to wake disabled

Hiya,
I'm working on the program so that you can have configuration option to simulate power button to put phone in sleep mode or jus to turn the screen off. This utility was just for people who want to save power whilst listening to the music, etc.
Please keep any ideas/suggestion coming. Much appreciated guys.
Watch the space guys....
That is great inítiative. I use the screen off function actually for the purpose to save power when navigation. screen off when there is a long straíght way to drive.
Put device to sleep mode will cause gps signal lost, which is not so nice.
I can image that there will be a lot of person who wnat to have different adds-on on this small application, it might be a solution to provide command argument.
Thank you.
I will try to see whether this one works for my purpose. Actually in my situation, I even don't want any key be locked as these keys are mapped for navigation.
How about screen toggle thus it is possible to map this application to a key?
awesome, i mapped the exe to a hardware key next to standby. now i can easily save power while wardr listening to music. ^_^
it combines very well with s2u2 locking function too.
big thanks!

Tom, may be it was to late to find your toggle light off switch, but it was very important for me to find it, thank you man, you solved a terrible issue for me, which is that programs stop updating (eg: twitter) when the device is in standby mode.
I heard that you can release another one, so my feedback is:
it takes about 2 seconds to turn off the light, isn't there any faster??? ))
This application is great. Combined with the S2U2 and HD Tweak i don't even have to use the power button at all. Device locked by S2U2 as soon as i turn off the light, waking up device by pulling out the stylus and rebooting with the help of HD Soft reset. Thanks
P.S. You should really add a decent icon, even though people can change it if they want to.

S Pen Question

Hey guys,
Is there a way to completely disable the S Pen to not write/do anything when it is in the air? It drives me nuts cause i can't control it and just scribbles or clicks on things when i don't want it to. I really just want it to click and do things when it is on screen..
Cheers in advance
simple, return it for a warranty
S-Pen
Hi
Go to ‘Setting’ - ‘S-Pen’ and turn off ‘Air view’.
A question to you: Do you have the problem that I have? If the phone goes into sleep whilst I'm reading something (this only happens at night when the ‘stay awake’ camera doesn't see me) and I wake the phone with the home button I go to the home screen and not to the last viewed p-ge. The only way I get to the last viewed page is if I wake the phone with the power putton.
Pressing the home button, just wakes the phone does not take me to the home screen. May its the app you are using, I am reading a PDF using Polaris.

This problem occurs if you freeze S-voice or disable the "Open via home key" in S-voice settings. You can unfreeze s-voice or re-enable the open via home button to get rid of the problem.
It's annoying, I know. Happens to me as well, since I disabled the double click to open s-voice because it induces a lag in the home button.

I've turned that off already. It still doing it though
The tip of your spen is stuck in, most likely. I saw a video of a guy tapping the end of his spen to unstick it, kind of swinging it. Best to get it replaced though.

Possible solution
This is a solution to the infamous S-Pen hover/pressing problem (where it will register a press when it's not touching the screen!)
I tried turning off air view, tried tapping and moving the pressure sensor tip... nothing seemed to fix it properly .. nothing except adjusting the potentiometers in the s-pen
The rough guide:
1. Remove the button from the s-pen (a sharp blade in the middle and levering up should do remove it but be careful it doesn't fly off somewhere unknown!.
2. Adjust the potentiometer (variable resistor) closest to the stylus tip (the writing bit). Turn it clockwise to make it less sensitive and CCW to increase it. A few degrees should be enough.
3. Replace the button - put the tongue side in towards the stylus tip and then rest the button on the stylus. Press the raised end towards the tip and down.
Test (actually you might want to test it before you do step 3!)
A big thanks to kevie88 on YouTube for suggesting it in a comment - a quick web search seemed to confirm it. I made a how to video that might help someone.
I called Samsung support and they are sending me a new s-pen anyway so I thought the above method was worth a go

Disable button on stylus

I forget the name of the button on the stylus that launches the wheel thingy, but it would be great it it could be disable completely. I use Lecturenotes and it's great that I can disable the wheel pop up, but I can't disable the button completely it seems. So if I am writing and I accidentally press it ( which happens all the time) at least the wheel pop up doesn't appear, but the word I am currently writing does disappear and I have to constantly write it again. I have the Bamboo Feel as well and it's awesome ergonomically speaking, but again it's the same thing. I tend to squeeze tightly when I write and I don't know that I can train myself to not accidentally push the button on the stylus. Would be nice if it could just be completely disabled.
I'm actually interested in this too, drives me nuts sometimes
Same here, I think it was put in a very bad location on the stylus.

Just go to Settings and in the tab Controls look for the S pen menu.
There you can disable the air command
Sent from my Samsung Galaxy Tab 10.1 Edition 2014
yeah, that stops the pen from bringing up the menu when you press the button but what we are looking for is what disables the pen button completely. So like, when you are writing the pen doesn't automatically switch into a select mode because you hit the button with your finger.
@arcadiua, JarkMackson & FLGibsonJr: This Samsung-specific functionality is provided by the system, no app can interfere here, as these touch events are not send to the app. I know of LectureNotes' users that have broken the S-pen button to circumvent the problem (either of the original or a second S-pen), but there are less destructive options, for instance to use a different stylus or to place the S-pen inside a `holder´ (which has the pleasant side-effect of increasing the S-pen size to that of a normal pencil).
if you don't mind a permanent solution. just pop off the button - it's pretty easy if you use a razor, just have something to catch the button when you pop it off. you should be able to then modify the button to not push the clicky thing.
while you're in there, you see to pots that you can turn to modify the sensitivity and offset of the pen if you're having any problems with them. i had posted a tutorial in the OG note 10 forum.

It worked!!! Just popped the button off with a razor, and then used that same razor to saw off the little nub at the end of the button that apparently would signal the button press, and then popped the button back on.
No more brief loss of the ability to write when I am in the middle of teaching.
Thank you!
jesus, thats super annoying. I need an eraser button for drawing. Looks like i need to buy a damn 3rd party stylus. Would be nice if the 10.1 at least supported tilt, then it would be worth dropping some money on an intuos pro pen...
I also use Lecture Notes as a student however I love using the stylus button. Lecture notes has the capability of using a single click as an eraser and a double click as undo.
BUT the most recent update has prevented me from using this feature any longer..
Now, every time you click the button it brings up the Air Command wheel and there is no option to turn it off.
Doesn't look like there is a workaround for this.. is there any way I could bring this up somewhere to raise awareness to the devs so they can enable an option to turn it off?
@mojo_jodroid: If you cannot disable `AirView´, the stylus button click is processed by Android/`AirView´ and does not reach LectureNotes.

i'm not sure what you mean by "the stylus button click is processed by android/android..."
@mojo_jodroid: It means that the input event `user presses stylus button´ is intercepted by Android/`AirView´ and removed from input processing (as if it never happened).

So I suppose my phone has the most weird hardware problem ever.

Please don't move my thread to Q&A as I already made a thread there but no one replied.
So what happens is that a touch is randomly registered on the screen of my phone sometimes when I press the power button. This isn't an HTC lockscreen specific bug as I have established it happens with PowerAmp lockscreen as well. I have done a full factory reset and it is still happening.
I don't use lockscreen security so the obvious problem with this is that so many times upon pressing the power button a notification is clicked and immediately opened as a result. This problem can be avoided by using double tap to wake but it's far too easy to activate by mistake so I can't stand it.
Repeatedly pressing the power button will not reproduce this result, it seems to only happen when the power button had not been pressed for a few minutes. But this cannot be a bug related to sleep mode since this happens when playing music as well.
So what I would really like to know is if there is anyone else with this problem? My M9 had been so perfect all this time but this has just ruined the experience. I don't exactly remember when this problem started but I do know it wasn't there from day one.

Seems like a hardware problem. Something presses your digitizer (touch screen).
If u have any screen protector , remove it.
If not, take it to warranty.
Good luck!

HTC doesn't provide warranty in my country so I am outta luck. I don't have a screen protector so I guess I am screwed.
I guess I won't be buying HTC again. I already tolerated the crack on my bezel but it seems every HTC phone has some hardware issues. It's too bad though because I loved HTC software and performance, the M9 had been nothing short of a spectacular phone for me.
It happened to me too when I used a stupid Samsung charger. Try another charger, I don't know why but sometimes the current of power is somehow overflowing the chassis of the phone that the digitizer thinks the difference is actually a touch on the screen.
I want to update this thread. As it turns out it's 100% a software issue. How I figured this out is that when I turn on "double tap to wake" this problem completely disappears even if I still use the power button for unlocking. So basically the bug comes into play when you turn off double tap to wake as it is turned on by default.
So is anyone not using double tap to wake? Are you experiencing this problem? Unfortunately I find double tap to wake extremely annoying as it is so easy to wake up the screen.

That's quite a unique software issue then. At the risk of sounding like an obnoxious tech support guy, I would absolutely backup everything and then just factory reset (or wipe and reflash your custom ROM) when you get the chance and quickly check if the problem is still there.
I've been using double-tap and it has actually been the opposite for me - I find it annoying how hard it is to wake up the screen because you need to hold up the phone vertically before double-tapping, rather than just tapping while it's lying on the table or in your pocket.

That's quite a unique software issue then. At the risk of sounding like an obnoxious tech support guy, I would absolutely backup everything and then just factory reset (or wipe and reflash your custom ROM) when you get the chance and quickly check if the problem is still there.

I have already done a factory reset to no avail.
That's strange because I can activate double tap to wake from any orientation.

Oh my bad re-read OP and saw you already mentioned it.
Hunh, I stand corrected I guess, since now I'm able to wake from having it flat on the desk. Could have sworn that didn't use to work. But still, I'm not by any means accidentally waking it (if I pick my phone up, it pretty much means I want to use it).
I can't replicate the digitizer anomaly, so not much else I can say other than good luck. Have you tried custom ROMs?

It might take a day or 2 of usage to replicate the problem, it doesn't happen most of the time.
I wake up my screen accidently sometimes when putting it into my pocket after locking it which is hugely annoying as the lockscreen is kinda easy to unlock once it's woken up.
I really can't be bothered with custom ROM as I am done with all of that. I'll just live with double tap to wake.

That's the design. When lying flat, you can wake the phone with a triple-tap.

Power Button worn out? Accidentally starting Camera despite clicking it only once.

EDIT: Fixed it (for now). Copied from my post on site 2.
What's up guys, I'm sorry for the late followup. It turned out, that I was too lazy to send it back. Now, almost a year later, I'd gotten into fixing phones and got the courage to open up the device and see what's up with the power button. It felt like the issue has been a bit less noticeable recently but I checked the replacement parts prices and how to open our phone up.
I think I've fixed the issue by adding one layer of electrical tape over the button-contact. I believe the issue is that the pin a just a little bit too short to reliably properly click the button.
Short tutorial:
Turn the device off and remove the simcard bracket.
It's actually super easy and you don't need to screw or remove anything. Google "Xiaomi MI A2 LITE disassembly screen battery smontaggio" you'll find a video, in the beginning the guy shows how to remove the backcover. I've used a hard, plectrom-looking "opening-pick" at the bottom, then carefully but firmly around the sites. You don't even need to remove the flex cable from the back, just make sure you don't rip it off. Cut off a short bit from the electrical tape, tape it from the battery to the contact, so it doesn't fall off. Close the case again, turn it on and check whether the powerbutton still clicks (doesn't stick) and test the screen lock. Post back if this has worked or if you've tried it.

Does anybody have a similar issue?
I've ordered the device from gearbest to Europe. Everything worked nicely.
However, recently when I hit the power button it sometimes triggers the double click interaction and opens my camera. I've tested a few ways to press it slightly from the side, with more force or less. However it will 1/3 times vibrate and start the camera like I had double clicked it, it's more likely when I hit it a bit too lightly though. Could it already be worn out after 2 months? This never happened when the device was new as far as I ran remember.
Yes I'm aware that I could change the camera shortcut but this doesn't stop me from worrying about whether my powerbutton will give out soon.
I was using the phone happily in the case Xiaomi has provided. Dropped the phone once and got a little scratch on the VOL Button but other than that, nothing crazy has happened. Does anyone have a clue whether they will still replace it? I'd gotten it in mid-August.

Buttons are usually the main gate to "planned obsolescence". I bought this device after my nexus 5 power button started working funny (I physically removed it and worked only with gestures). So, now I try not to press the button unless necessary. I unlock with fingerprint, and lock with Greenify.
In other words. Make sure of it, if the button starts working funny, I'd file a warranty claim. Or it won't last long and warranty will expire eventually. It can happen with this device and with any other piece of tech.
My opinion.
If you do place a warranty claim, let us know how xiaomi's customer service works in Europe.

when you dropped it
the power button may have got stuck
this is possible and I've seen it on some other devices
you can open it yourself if you don't care for warranty like i do
but the safest option is to claim warranty and yes they would replace it

I have the exact same issue. It started when I installed the Oreo update, but it could be a coincidence. I'm still looking for a fix.
It also happens to me, and I didn't drop the phone... Is there a way to change the shortcut to, maybe, press the power button 3 times instead of 2?

It happens to me too, I disabled the shortcut and just not using it right now. I don't think there is a way to change the shortcut
It happens to me....
It happened for me as well.
And i think it's a software bug, not hardware..

Same here, never crashed on the floor, it's software issue

It obviously is not a software issue. This means that they've used cheap contact points on the button if this happens to many of us. This is a hardware issue.

I'm having this issue since day one. It is obviously software, otherwise the same contact problem would occur when turning the screen ON, but it never happens. Solution is to disable the feature under System -> Gestures -> Jump to camera.
i also dissabled the camera gesture because of this issue.
im sure this is reasoned by a more or less loose power button and not an software issue

How can that be a software issue? Same issue happens to me whenever I use the power button, either to lock the screen or unlock the screen. Also if it was a software issue, it could be fixed via installing a GSI. That doesn't fix it either.

Let me break it down and you can tell me if I'm missing something.
1. Many users are reporting that the camera app starts when pushing the power button to turn the screen off.
2. They are not reporting any other issue with the power button, like the camera app starting when they try to turn the screen on, the button being irresponsive, or the camera app NOT starting when they deliberately push the button twice.
3. The problem reportedly goes away if the double-push gesture is turned off in settings.
Do you still think this is a hardware issue?

When I disable double press gesture from Gestures, still when I sometimes hit the power button, the phone locks and closes the screen and then turns the screen on again which means that it still registers one presses sometimes as double presses. Also if you've ever used a keyboard or a mouse or anything electrical with buttons on it, these appliances do the same sometimes even though you tap one button they sometimes register it twice. Which is a hardware issue. I still can't see any software issue here. When you disable the double press gesture, it doesn't launch the camera anymore but it turns on the screen after locking it (sometimes as usual)

Not for me, so it's possible that these are actually two different problems with this phone. I wouldn't be surprised. :laugh:

Yeah me neither. They don't look like they're going to fix anything or listen to users either. I'm happy with stock Android though.
Hi guys, for me, the problem has fixed disabling the option "Power button lock the phone", and set the option "Lock automatically": immediately.
The fix

I changed the power/volume button assembly outright just the other day, and so far I'm not getting this issue anymore.
I recorded myself doing it here, so you can see how easy (or hard) it is: https://youtu.be/q8kaY-v0q_Q
