Samsung Galaxy A41 Touchscreen Sensitivity Problem - Recognizes Touches As Swipes

Hello.

https://eu.community.samsung.com/t5/galaxy-a-series/samsung-galaxy-a50-touchscreen-sensitivity-probl...

 

I have got the same problem as he/she above.

 

My phone is too sensitive for my uncoordinated fingers it seems. Is there an option to reduce the sensitivity so that a touch wont be counted as a swipe?

 

::I try to start an app. My touch is not recognized as a point but a line with a dy(diffrence between start/end y-coordinate of touch) of ~+/-28Pixel. My Samsung Galaxy interprets this as a swipe and wont open the app. 

Same is true for hyperlinks, etc..

 

Is there a solution?

thank you

TLDR: Samsung I need a setting that lets me determine which parameters(dx,dy,Xv,Yv) must be met for a drag or a touch.

Good day,

 

so I still got the "problem". I have done some research. Swipe seems to be the wrong word to use.

https://stackoverflow.com/questions/22843671/android-swipe-vs-fling


  • Drag: Fine gesture, slower, more controlled, typically has an on-screen target
  • Swipe: Gross gesture, faster, typically has no on-screen target
  • Fling: Gross gesture, with no on-screen target

I think I have got a Drag problem?

 

Here are some data points. Most of them were experienced in chrome(duolingo) and at the homescreen. 

 

Touch or Drag_Swipe_Fling_.png

 

green dots == touch (start the app, accept my answer, etc.)

red dots == drag (do nothing)

 

In this case: inside the circle is recognized as touch and outside as drag

 

but as you can see(green dot outside the circle) that is not the whole picture.

 

After some researching:

https://developer.android.com/training/gestures/detector

There are two more parameter the speed of the pixel-change in the x and y direction. Four paramters (dx,dy,X-velocity,Y-v) decide if it is a touch/drag/swipe/fling. After that I gave up.

 

SAMSUNG: I need a setting that lets me determine which parameters(dx,dy,Xv,Yv) must be met for a drag or a touch.

 

Please!

Thank you
