so i just upgraded from an old lg optimus 4x hd phone (android 4.0.3) to a new xiaomi redmi 4 prime (android 6.0.1) and what is annoying me most is a strange software effect filtering all input motion from the touchscreen.
for example when im trying to scroll in settings menu, but moving the finger slightly up and down, the motion is getting filtered completely. when trying to scroll slowly the lag/filter is most annoying. with android 4.0.3 this doesnt happen, all motion input from the touchscreen is getting directly forwarded without any delay/lag/filter.
this touchscreen input filter behavior also occurs in apps like for example realvnc viewer, with android 4.0.3 its pretty easy to accurately control the cursor, with android 6.0.1 its almost impossible to control the cursor because all touchscreen input motion is getting filtered/delayed.
is there any way to disable the touchscreen motion filter behavior and make the touchscreen input to be direct like it was in previous android versions like android 4.0.3?
I have now uploaded 2 Videos of the Xiaomi Redmi 4 Prime and LG Optimus 4X HD which in comparison should show clearly what i mean with "touchscreen input motion filter":

youtube.com/watch?v=_ac1RgK2Xhw
At 0:00-0:37 (and especially at VNC Viewer test 1:21-1:53) you can clearly see how the Xiaomi Redmi 4 Prime creates some kind of a "smooth-scroll-effect", it continues scrolling very slowly, even though the finger has already stopped moving. This clearly must be a software effect, i cant imagine a hardware problem.
At 0:37-1:21 and 1:53-2:36 you can see, how much the touchscreen has got an input travel almost like the steering wheel of a car, smaller up/down/left/right movements are just being ignored and filtered out. Also here i can only very hardly imagine that this is a hardware issue, for me it clearly looks like a software effect.
I also tested 2 other Android 6/7 phones (Cubot Note Plus and Homtom HT17 pro), both show exactly the same behavior as seen in the video of the Xiaomi Redmi 4 Prime.
The questions that im now asking myself are: Where does this touchscreen software effect come from? What is it called? And how do i remove it? (If necessary, i also agree to root/unlock or install a custom rom on my Xiaomi phone)

Try SGS touch screen booster app.
It let's you adjust the motion filter amongst other touch latency Android touch settings and you don't need root.
I'm aiming for as close as I can get to iPhone iOS touch response...
Still playing with it but this is where my Honor 8 is currently set.
Couldn't be happier with the results
Hi, I take photographs with my mate 20 Pro remotely, using Bluetooth headphones to take the shot (wildlife snaps). Thing is, Emui camera app doesn't seem to have an adjustable screen on time for the camera app. The screen turns off after around 40 seconds, which is no good to me. I want it on much longer, preferably all the time.
Is there any way to adjust this you folks?!
I have my screen on time set to 10 minutes on settings and no battery saving set manually.
I was wondering if there is any app that could emulate the Smart Stay feature found in Galaxy devices, for Poco F1. I was an Honor Play user and it has that feature as well. Basically what it does is it uses the front camera to detect if someone is looking at the screen, and then prevents the screen from timeout.
I've been on Android for years and only when I upgraded from Android 11 to Android 12 has my Auto-Rotate constantly been turned on, even as I turn it off every single day whenever the darn thing rotates on me.
I NEVER want my phone screen to rotate.
Yet, it does.
Why?
I googled and found out that Android 12 did add to the "intelligence" of the auto-rotate functionality; but I don't see others with the same problem that I have that it keeps turning itself on even after I have turned it off.
How to use Android 12’s clever new auto-rotate system
With Android 12, Google has introduced a smarter way to control when your screen switches between its vertical and horizontal orientations. Instead of relying solely on your phone’s accelerometer to figure out which way you’re holding the device and then rotate your screen accordingly, Android 12 allows your device to use its front-facing camera as a guide. That way, the software can sense how that striking face of yours is positioned at any given moment and make sure the screen is always positioned to match. The advantage is that you then avoid those awkward situations where you’re lying down — and thus holding your phone at an angle — and the screen then flips into its landscape orientation when you’re actually looking at it in its portrait mode. Since the system pays attention to the position of your face, it makes the screen match the way you’re actually using the device, no matter how you might be holding it.

I do NOT know if that Android 12 "intelligence" is the REASON my phone keeps auto rotating, which is why I'm asking here if the rest of you are also having to turn OFF the auto-rotate time and again, day in and day out, all day every day, on Android 12?
And yes, I searched first:
Search results for query: rotate
Search results for query: automatic rotate
Search results for query: auto-rotate android 12
It doesn't seem to be a problem for others - so why is it a problem for me?
Anyone have any debugging ideas to figure out WHAT is turning on the automatic rotation feature of Android?
Hi, apparently the Activity Launcher doesn't work for MIUI 13/ Android 12. At the same time, the phone use PWM and has terrible flickering, has anyone found a working solution to the problem?
Thanks!
Hey nova launcher work perfect

Activity Launcher, despite the name, is not an Android launcher. It is a tool that allows you to launch and create shortcuts for hidden apps/services. It's popular because it allows modifying the "Anti-Flicker Mode" setting available in some ROMs but hidden from the Settings App.
Nova Launcher, as an Android launcher, cannot enable DC dimming. I don't think DC dimming is possible with this phone at the moment.

Thank you very much for the clarification.
It's a shame that there are no solutions to the screen flickering problem for this lovely phone. Interestingly, the Xiaomi Redmi Note 11s uses the same display, but there the flicker is much less and appears below 54% brightness only, while here it is even at 100% brightness, which is terrible for the eyes...
I haven't actually observed a flickering problem. I'm on MIUI 13.0.9 (Android 11) and can't even observe it at low brightnesses. I keep my display refresh rate at 60Hz to improve battery life, I don't know if that makes a difference? It's not a hardware issue with your device is it?
Use a camera on another phone, set it to pro mode, and choose a shutter speed of about 1/500s. Now point the camera at your phone's display and start dimming it. You will see black bars running all over the display. They are not visible to the naked eye, but at the same time your brain indexes them and if you stare for a long time they will give you a headache and damage your eyes...
This is called PWM and is characteristic of AMOLED screens, which is why they put so much strain on the eyes, unlike IPS screens, where the image does not flicker at all, regardless of the brightness of the screen.
btw my phone updated to android 12, is it possible to downgrade it back to android 11 or is there no such function in the menu?
You could probably flash the old firmware through adb, you could open a new thread and see if anyone has done it?
