So i bought the a50 cause i wanted a bigger phone like the note at a cheap price. Loving the phone, so i decided to spring for an active stylus, the stylus actually works very well on my g6 and dell touchscreen but for some reason the upper half of my a50 isnt very responsive, and where it does respond is only on the edges. If i start a stroke from the bottom of the scren it will follow through to the top, most of the time. But if i start at the top and move down, it only appear towards the bottom off the screen. Tapping is even worse, almost no response on upper half.
I have no magnetic cases, ive tried two a50s, with and without screen protectors. Always the same result. Heres some pictures to help visualize, does anyone have a fix for this?

You could try increasing the touch sensitivity.

Thank you for your response. I should have mentioned, the problem is identicle, with or without touch sensitivity increased. The stylus work on a note 9 perfect as well. Starting to suspect its a software problem with the a50.

every review i've read online before i bought the unit was boasting about how "finger-friendly" the TP2 was, and that you could lightly swipe your finger across it to navigate the menu and that the touchscreen was very sensitive and whatnot
however after 2 weeks of use i find that to be relatively untrue. i've got to apply a fair amount of pressure on the screen to get it to register my input. of course, i'm posting this because i'm afraid that i might be damaging the screen in the process
i have no basis for comparison actually, my only 2 other touchscreen devices at home are an iphone and a cowon s9, both use capacitive screens. i always knew there was a big difference between capacitive screens and resistive screens, i just didn't know it was THIS huge. i can actually slide my finger lightly over the iphone's surface and its registered properly. the sliding probably feels smoother as its glass, but i can live with the TP2's plastic. what do you guys think ? should i get it checked out at the HTC store ?? its on the other side of town, don't wanna waste a trip as if its not a problem
oh yeah and just to get this out of the way, the screen is a membrane and not a hard surface right ?? everytime i press on the screen using my finger or the stylus, i can feel the screen slightly moving down, can also see the surface getting slightly dented at the point my finger pushes it if looking at it from a certain angle.
ps before somebody asks: i only got to test the keyboard at the telco store, some punk had cracked the screen of the display set, so i didn't know about this screen issue until i actually purchased the set
sorry for the long post, but i'd really appreciate any comments
TIA
Well, I don't have an Iphone so i can't tell you about how it compares with the TP2, however, i found the display to be much better than the one on my old XDA. It will probably never as good as a capacitive device like the touchpad on my laptop, but I found it to work very well. You have to apply a certain amount of pressue to the display, because it reacts on pressure, so I guess there is nothing wrong with that. I also see a small dent when I use the stylus and press the display. I cannot confirm the screen slightly going down when pressing it.
To summarize it, i use the Stylus 90% of the time. It glides much better on the display than my finger does so the overall experience is slightly better when using a stylus. Plus i don't get any greasy fingerprints on my display.
However the 10% I use my fingers to work on it (and 25% of that 10% is spent on polishing I found it to work pretty well, so in general I don't think that the reviews were off when it comes to finger usability.
What you are describing is probably normal. Resistive screens do require pressure. The TP2 tends to require less pressure than others, but nonetheless it does require it. There's no comparison if you compare it to a capacitive screen device because those don't require pressure at all.
The flexing of the screen that you described is something all resistive screens have. Again, if you compare the screen flex of the TP2 to earlier HTC devices, it's greatly improved.
To be on the safe side, go to a store and try out other resistive screen devices and see if you experience the same thing as your own. Then you'll know what is considered "normal".
thanks for the replies, i'll probably head down to my telco's store and see if they've replaced the display set then.
any other comments ??
You know I thought the same, waiting for a cab to increase the sensitivity because at the moment its quite annoying pressing buttons more than once...
From a few years to nowadays i´ve always used QTEK/HTC devices, my latest one is, ofcourse, HTC RHODIUM, the rom it has installed is RUU_Rhodium_HTC_PTG_1.19.410.0_Radio_Rhodium_3.44.25.27_Signed_Ship, and the screen is very sensitive and responsive, i´m just very pleased with it overall, it´s the best.
Cheers.

you don't need .cab
just change in registry...
HKLM/drivers/Touch Driver/pressurethreshold, (default=10000)
(I might not remember perfectly, but it's something like that)
try this?

this might help just re align your screen again using little pressure then your screen will not need some much pressure to work.
I have found the this not only aligns the screen but the pressure as well.
mine I just have to lightly touch it and dont have to press very much at all.
Cheers
Hey Guys,
I know that most of the questions I read were about the S Pen being too sensitive. But in my case, I feel the S Pen is not as sensitive as it should be!
When I put the pen in the slightest contact with the screen and try to scribble, nothing comes up. I feel I have to push the pen a bit more strongly to get some writing on the screen - and that takes away from the sensitivity of the S pen which Samsung brags about.
Is anybody else facing this problem, where you feel the S pen has to be pushed too hard for it to start writing on the screen? In my opinion, as soon as the pen comes in contact with the screen (even the slightest contact), it should start writing.
Thanks guys.

I am having this issue a little now. At first the s-pen was fine and performed as expected but now it seems like it needs more pressure to register scren taps etc although the pointer shows as normal whent he pen is close to the screen
This is normal in S note and some other apps where pressure sensitivity is needed. Samsung has designed it in that way.
Same here, first day the pressure needed was very low, now I need a lot of more and the traces of the pen have like 2 options, little press (more than before) and a lot of pressure for thick lines, nothing in the middle.
And I can corroborate this because with my other wacom pens of tablet pcs doesn't have the problem of the samsung now.

read this thread http://forum.xda-developers.com/showthread.php?t=1925212 Apparently there are two adjustable potentiometers beneath the S pen switch which can be adjusted for increasing or decreasing sensitivity of the pen . most people including me are suffering from greater sensitivity . I adjusted the potentiometer to get rid of this problem.

The thing is that my pen can write with slight pressure but a little more than before, but the real problem seems that the middle one levels are lost and were working the first day.
Maybe I'm just retarded, but I can't seem to find the setting to recalibrate my screen.
It's been slightly annoying me because I bought one of those fancy adonit styluses, (The ones witht he plastic disc, supposed to be more precise), and it works great, however when I turn on the "show touches" function, the touch from the stylus ALWAYS registers slightly towards the edge of the screen.
If I touch in the center of my screen the touch registers dead on, but the closer I get to the edge screen, the further off it gets.
I've noticed something similar on my tablet. But in my case, the best alignment when showing touches is in the upper left corner of the screen. As I move farther down, the touches start to come up slightly down and right of where the stylus is touching the screen.
So It's been a couple of weeks and Ive still yet to find a way to fix this slightly annoying accuracy issue. Does anyone know a way of doing so?

Try flashing ts-20 from sfnub's thread, works better for me
So far my new zenwatch has been great. However, I have noticed in a couple apps such as Multi Calculator for wear, that buttons at the bottom like . and at the top like ac/c don't respond very well. Then I noticed that throughout the entire watch interface, the top and bottom 1/4 of the screen (not the bezel) are entirely unresponsive to touch. I wanted to see if this was a defect or possibly a byproduct of that curved glass not allowing the capacitive sensor to extend beyond that middle portion of the screen. Does anyone else notice this?
I've mostly been marking it up to bad aim on my part but it seems to me that I often miss touches in the upper right corner. Too soon to tell if it's the watch or just my shakiness.
Yeah I thought my aim was off too. Try dragging from the top on the watch face screen. You'll notice it actually starts to pull it down a few millimeters from the top. I was hoping it was a defect so I could just exchange it but my fear is that they all do it and it is not fixable via software.
I agree that the first couple of millimeters of the actual screen don't respond but nowhere near 1/4 of it.
I notice this on my zenwatch after using an lg g watch, g watch r and moto 360 all side by side. The zenwatch also seams less accurate on thing nlike minuum keyboard and generally with scrolling. I suspect a cheaper less accurate digitizer has been used?
On mine I can hit the topmost part of the screen, the bottom, and all corners. I turned on "Show touches" in the developer options to make sure it registers where im touching. If you test it that way, you can see if its a defective screen or just accuracy issues.
The lower left of my screen is not as sensitive as the rest. Clicks take a few tries and scrolling is missed. The only one?

Is there a specific app you notice this on or just everything in general?
Obvious one, but do you have a screen protector on?
It’s in all apps and the fingerprint reader scroll is also not as sensitive. I have a thin film protector on the front but I have the same on the Pixel 2 XL and can barely touch it and it responds. LG vs Samsung?

Could be a quality control issue. Just because it's the same brand doesn't mean it will behave exactly the same. Could be thicker in that portion and cause touch issues
Sent from my Pixel 3 XL using Tapatalk
Maybe the material makeup changes in different areas if quality control is really bad I guess. But I don't think the material is interfering with the touch sensitivity I think you would have to visually be able to see it's thicker in certain areas for to make a difference. I've got another one on the way and hopefully it changes things.
Top left of screen not sensitive anymore?
Something similar happened to my Google Pixel 3XL too. Top left corner not as sensitive as compared to when I first got it, not sure why?
Initially, I thought it's due to my new screen case, but after removing and putting it back, it did no difference.
Hello everyone.. i just bought pixel3Xl and i realised that
I miss Touch Screen Sensitivity....
Not every time but it happends and is so noisy..
I have a Good screen protector thow!!!
Any news if its a software bug or the screen protector?
Are you choose option hide notch on Developer option ?
Nop!
I'm having issues with touch. Last night when I was browsing as usual, my device started abnormal behavior and got stucked for unknown reason. After rebooting manually I found that touch response is so slow and have touch with force. Any kind of help on this is highly appreciated.
