Improve touch sensitivity - Xiaomi Mi A1 Questions & Answers

Hi, is there any way to increase display touch sensitivity? Im asking because I use a screen protector and its really unsensitive.

Maybe is there a way we can change/modify/downgrade/upgrade our touch screen firmware.
Does anybody know which touchscreen firmware we have?

Switch to a better screen protector. The 'full glue' ones have better sensitivity than the ones with 'dot matrix' especially in the corners.

I think I have the glued ones, its not bad, but it just slightly less sensitive. Typing on keyboard is a bit tricky, but I got used to that.

Screen question

Hi,
I've watched numerous videos of this phone, and it looks as though the screen on the HD2 is quite reflective, has anyone had an issue with this?
Cheers
When using it in sunlight, you can see yourself. If you don't mind seeing yourself or what's behind you, then it doesn't cause a problem. Just think "any other mobile phone screen". Nearly all phone screens are glossy when off, it just dpeends on how bright you set the backlight. Set your current phone's backlight down a tad and you'll probably get the same effect. Then you can decide if it worries you.
You can also get screen protectors that are polarizing and reduce glare ......

Touch Sensitivity?

How is the touch sensitivity on the Nexus One? I ask because my myTouch 3G has serious sensitivity issues towards the edges of the screen. It either won't register a touch or it will only register after pressing harder than normal.
Also, how is the sensitivity compared to an iPhone?
I would say its equal to the iphone if not a little bit better.
Supposed to be a capasitive display, so no need to press at all, touching is enouh.
some time is good, some time is not very responsive, my friend say the weather is too cold, it need to warm up to working. just kidding

Well, the myTouch 3g also has a capacitive touch screen, but mine definitely has sensitivity issues. For instance, when viewing a video, it is extremely hard to jump to different spots using the slider at the bottom of the screen. It just won't respond most of the time.
i knwo what you mean. i had a mytouch 3g and switched to nexus one. I can confirm sensitivity on nexus one is MUCH better, on par with an iphone.

That could easily be the processor not responding, not the screen...
How does the screen feel?(is it glass like as on ipodtouch/phone)
I have the g1 and I hate the plastic feel of the screen. Makes swiping feel odd
In didn't expect to be this impressed to be fair. Only thing so far is I keep missing the spacebar when entering text
the nexus one screen is glass.
I haven't had a single problem hitting menus/keys and I can safely say I love the touchscreen and response from the N1 more than my iPhone & iPhone 3G.
Screen sensitivity doesn't seem to be as good as the 3GS, but it's really so close that you would have to have used an iPhone for 3 years, like me, to really be able to tell the difference. The difference is so small that most likely won't notice it, but you call tell the difference when trying to select links in the browser, without the trackball, for example.

Touch Screen Doesnt Always Respond

Hi
Anyone else having problems with the touchscreen taking maybe 5 presses for you to be able to select for example a menu option? This is really starting to bug me now. So much so I'm thinking of sending it back to t-mobile and cancelling the contract.
Any help/suggestions would be appreciated.
Cheers

Try an Calibration in the settings menu.
There isn't a screen calibration setting on this handset. I wasn't aware we had to do this on these capacitive screens.
My X10 doesn't work like that at all. How hard do you press? Does it work in one press if you press harder?
Press harder on as capacitive display?
You'll have to place your second hand on the metal frame and it'll work perfect.
Dry hands are also not good.

Yeah. If you press harder a larger area of your finger touches the display. I.E. more for the digitizer to sense.

I'm definitely noticing this. I'm not exactly the type of guy to regularly moisturize my hands. I work in construction, and this capacitive screen absolutely sucks for me. I've been using resistive screens beautifully up to this point. I find I often have to lick my thumb regularly to get the screen to work properly. I have a ton of trouble unlocking the phone, since the screen thinks I've lifted my thumb halfway through the pattern. Using swype is a nightmare for this reason as well.
There are resistive multitouch screens on laptops and desktops now. I hope we see a swing back to resistive screens on smartphones.
I'm experiencing this problem aswell an i'm pretty much sure this is all software related, you can actually see the interface reacting to the press but it seems like the device never executes the action forcing you to press multiple times, annoying as hell yes! I sincerely hope SE fixes this in the next update.
Has anyone had any problems with accuracy? In some apps the touch registers like 5mm below where I actually touch.
I think the stock screen protector hinders the touch sensitivity quite a bit. Try getting a thinner screen protector. There is a thread talking about how sensitivity and accuracy improved when they took theirs off.

Thanks for the tip but I already have an uberthin protector. That brand has worked very well on all other capacitive displays I've had. I'm suspecting a software bug rather than a hardware issue.

I jammed my X10 in a sports armband for Ipod touch, it has a very thick plastic window and it did not affect the sensetivity a bit so i dont think the thin stock protector will do any difference. Just my opinion

I've noticed that on the dialer application.
Sometimes, while I am on Recent Calls section, I press the green telephone next to a contact and it calls the one right below it!
Haven't ever noticed any sort of oddness like that... and I have a thick screen protector on top of the stock one.
Occasionally I'll type a letter wrong, but that seems to have improved with the update from two weeks ago.

Low screen sensitivity

Just bought a new Nexus one to use while I'm overseas (used an EVO 4G back in the states) and one of the first things I noticed was the touch screen seems considerally less sensitive than the one on my EVO. I find myself having to hit the screen multiple times because the first touch didn't register often. This applies to the capacitive buttons on the bottom of the screen as well.
Has anyway used a Nexus One vs. another phone and noticed its screen being slightly less sensitive. I have the SLCD version by the way but I think it uses the same sensor as the AMOLED so I'm not sure that makes a difference.
The N1 has a crap digitizer. It's one of it's weak points sadly.
Hit the capacitive buttons slightly above where you think they are. Works every time...

+1 especially its alignment is really inaccurate when using the multi touch function
It is kinda rough. But not too bad. Maybe just a bit worse then my HD2.

dots on screen ?

i was looking on one device on the bestbuy store and when i was
deflecting the device i could notice the a matrix of spots/dots on screen
that never disappear only if i hold the device in some angle it would be not noticeable...
so i wanted to ask:
1. Am I the only one that saw that?!
2. if i will put a protect cover on screen it will make this dots/spots not seen?
Perfectly normal. The glass is supposed to be Gorilla, so I wouldn't even bother with a protector.
Sent from my Kindle Fire using xda premium
why is that normal ?
i haven't saw that on a PlayBook or a iPad or a Samsubg tab...
so why is this normal ?!
That's the grid for the capacitive touch sensor. On some devices it's more visible than others. I guess Amazon is using one of the more visible ones on the Fire.
Since this is bothering me very much, do you think if i would apply over it a protector it would be non-visible ?
Eh I can't see it on mine at all. Maybe It's just the display.

I doubt it, but you can try. FWIW, I can see the dots, but they only appear at an angle with certain glare on the screen. Doesn't bother me.
It's normal. You most likely noticed it due to light reflecting on it at a certain angle. My ipad had those, and my touchpad has them. I don't notice it unless the screen is off and its held at an off angle with a good amount of light reflecting off the surface. You don't notice it while it's on.
This was VERY visible on my Nexus One, but isn't on my Sensation. It's back on the Kindle, but you only notice it when.the screen is off. It depends on the display, and I think the more reflective the screen, the less you see.

It has both dots and also a grid matrix. You can see it on every one, just have to turn the unit *just so* to see it.
My understanding from a post on Amazon about the device is that its not a capacitve or resistive touch screen but an infrared touch screen.
Confirmed myself that it is not capacitive as you can touch it with anything and it responds, where my iphone and Captivate do not.
Food for thought. Has anyone else heard of an IR touchscreen before?
Ive always been able to see the dots on every touch device I've owned. Just requires the right angle and light.

Yeah, they're just rarely used, because the technology has only been reasonably cheap/simple for a few years (iirc), whereas capacitative and resistant touchscreens have been around for much, much longer.
Also, touching the screen with a pen lid doesn't do anything for me. You sure it works with *anything*? I got it to work with a piece of moleskin, though, so... maybe it's just certain things?

Was just able to unlock using a paper napkin folded three times to make sure it wasn't skin touching anywhere. Tried with my leather wallet and it didn't react. Very strange. Also tried a microfiber cleaning cloth, didn't react on my iphone or captivate but worked on my fire. Wheird.

The Kindle with the IR touch screen is the Kindle Touch, which uses the IR touch screen because capacitive touch screens aren't available for the E-Ink screen yet. IR touch screens work by shooting IR lasers across the screen in a grid format, so a touch would trip IR lasers, and which lasers are tripped can be used to calculate where the touch is in. That's what they use on the Nook Simple Touch, too. I remember my old car built-in GPS was an IR touch screen. You could trick it by blocking the IR receivers.
Nowadays, most LED touch screens are capacitive, which is what's on the Kindle Fire (the reason why there's dots on the screen - I think they're the sensors that measure the capacitance to calculate the location of the touch).
