Touchscreen is not always responsive: bug or feature? - Samsung Galaxy A20 Questions & Answers

My Samsung S7 touchscreen has always been very responsive.
My Samsung A20 touchscreen is not always responsive, and sometimes I need to touch the same icon twice.
Is it just because the CPU is slow and busy to process touchscreen requests?
Or is it the intended behavior of the user interface?
What can I do to make A20 more responsive?
I do not use screen protector. I have the latest stock firmware, security patch Feb.1, 2021 and just a few apps installed. Android 10. One UI version 2.0
Samsung Members app hardware test does not detect any problem. Wiping cache does make any difference.

Very strange.
Is it rooted?

No, not rooted

On my phone, I only use my Google account and do not have a Samsung account. Could that be a problem? Likewise, could it be, for example, due to Google backup or Google sync in background?

Problem with Galaxy Note - Lag

I've recently bought an international galaxy note and I love it so far, except for the fact of the high ram usage. This was not a problem on my previous Samsung device, the Galaxy S2. Typically after pressing the "Clear Memory" key I get around 360 MB/800MB of RAM being used. However, as I open a few APPS, such as Facebook, double twist and internet browser it spikes up to around ~ 760 MB and my device gets EXTREMELY laggy. 3 open APPS shouldn't be a problem right? Even after I press the back button (not home) the device is still lagging. Is there a reason for this?
I am currently on:
Android 2.3.6
Baseband N7000XXLA4
Kernel version 2.6.35.7-N7000XXLA6-CL907341 [email protected]#2
Build number GINGERBREAD.XXLA6
***My device has the latest update and is not rooted.***
Thanks!
Suspending an app in RAM does not cause the device to lag. What causes ANY device to lag is when the app is running FULL throttle in the background.
Check to see which app is still running constantly in the background that's using most of the CPU power.

Setting > Running Applications. I have a lot of my recently opened apps "cached background process"
I let the OS handle to open apps, since if you close them, they open again if needed by the system. However, apps such as games I ensure I quit when I'm done.
Sometimes when the lag is excessive, I need to do a reboot and then the SGN works speedily again. I found after uninstalling an app called Swift Keyboard, the lag minimized. Shame, as it's a super keyboard replacement.

really now? I have swift key installed as well. I'll uninstall it and see if it helps, though it seems strange that would induce lag.

Do let us know how it goes pl.?
have you installed any other launchers. there is one called go launcher. this has got the running applications easily accessible. from here you can control the apps.

Well Swiftkey X is "unoptimized for tablets" so I downloaded the free tablet version and there was some minor improvements I think? But it might more of a placebo effect.

I have launcher 7 installed on my device, but currently have TW launcher set as default.
***I currently have 10 applications open without any lag whatsoever. I'm not really sure why my device was lagging before but it seems that random problem has been solved on it's own.****
Thank-you for the two of you for giving me tips, it was much appreciated

Your device is NOT on the latest update. LA6 is from Janurary. There have been several updates to stock since. (Not that I would ever run stock ... You ARE posting to a DEVELOPER forum...)

Darn! I never knew, I just got my note a few days ago and the software update on the device says its the latest update. Strange =O
Thanks!
I would try the tw launcher. It made a fairly noticeable difference as far as lag goes.
I got tired of all this, I eventually decided to root and now I'm rocking a ics build rom.

Lag problem in system application
Hi, I am enjoying my Galaxy Note but I am facing lagging/jerking scrolling problem in Message, Contact and other system application but no problem with Internet or any third party application.
My Kernel is : 2.6.35.7 - N7000DDLB2.....after update (dont know what was original)
please suggest how to solve it.
There are lots of posts relating to laggy Notes.
Short of rooting the device, there is no solution other than to carefully check what you've installed on the phone, when you've exhausted that avenue then all you can do is to sit back, join the queue and wait for the ICS update...

It even had lag at the store : (
Hey y'all!
I just recently returned a HTC One X cuz i wasn't feelin' the ICS vibe, i NEED a Menu Button and thats THAT!
So here i'm thinking 'bout gettin' the GNote, cuz its STILL on Gbread (my fav Android Op System out of all of 'em to date) but then all i read is how bad the lag is (which as mentioned in title was evident even at the store) but can be fixed by rooting & flashing ICS ROM.
Soooooooo, IF i root (omg i hope its a lot easier than it used to be no tar, pit, odin files... is it? wait, don't tell me! i don't wanna know, YET...lol) will my GNote Menu Button still bring up a Menu or does it become useless in an ICS ROM?
Also, if i don't root and wait for Official ICS update, will Menu Button still be functional? I thought i read on 4 button phones u still can use the M Button, but now i can't find the article...
thanx y'all!!!

Nexus 6p freezes when installing/updating apps please help

Hello guys, ever since I got my phone. Everytime the phone trying to do update an app or installing one it froze for a new minutes until the apps is installed. It was like that on stock and it is like that on every custom roms I've tried. I don't know if I'm the only one or not. Please help and thank you.

No, just for a few mns until the application is done updating/ installing or un installing Then the screen either hang or locked itself. Like the system did a soft reboot.

It's normal for a device to slow down or lag a little when installing apps sometimes, the screen locking definitely isn't normal though.
Even my does the same
Like it i update am app or install from play store and use a diff app say I'm on whatsapp then when the app is installing it will be freezed no touch works nothing but screen remains as it is
Cheers ?

Even when installing app? That's odd. My note 5 doesn't freeze when installing apps or updating them
It's an issue with aosp package installer. You won't see it on other devices as the oems re-write that code.
It's mostly noticeable on anything FB puts out. As they are known for having the worst coded apps on the market.

So far I don't think there is a fix. Can't say about official Google. As I have not run a stock rom since I got my first device. If they have fixed it they have not pushed the fix to aosp which is happening more and more with google

Well as the custom roms sync their source with aosp, then Google has not pushed a fix if there is one. This is happening more and more. Google fixes something but doesn't push it to aosp so it stays broken in 3rd party roms until the devs find a fix
Has this been solved? It's happening to me.
facing same issue. Also my YouTube pause video whenever some app gets updated in background.
Noticed this along with horrible battery life due to system ui restarts or something in all latest may version of Roms. I went back to b29I or whatever "I" version stock rom. No problems since. Goodluck

Nougat or Whatsapp crashing

Hello!
I have a samsung s7 edge and after the update of Nougat the phone is not working correctly.
Especially when i use whatsapp & viber the keyboard has a big delay when i write something and when i go out from a chat the keyboard remain in the screen for 2-4 sec.
I tried to run some apps like malwarebytes or to run from setting menu the device maintenance. I tried also a factory reset which was the most effective solution but just for 1 week. After the first week the crashing in the apps came back.
Any thoughts for solution? \
Thank you!
Disable the prediction and the lag will stop
I have this too. On Nougat and GBoard. Super annoying. The other thing I noticed is that the voice icon disappears from the keyboard and have to restart the phone.
Are you runing stock Samsung rom? Also did you flashed a custom kernel? This looks like some cores are off to me but i might be wrong...

Android 7 ETA?

Does anyone have any clue when Android 7 will land on the Zoom? It's kinda silly that it didn't launch with it to begin with. But the year older Zenfone's have since received Android 7 and we're still waiting ..
Already launched. Updated today.
1.2Gb download
Oh wow, look at that timing
I hope it doesn't cause the white line issue when I install it!

Anyone attempt to do this with bootloader unlocked and with TWRP? I'm assuming I'm going to have to attempt to flash back to stock recovery to do this.

I just downloaded the update, I'm gonna leave it charging and updating. :fingers-crossed:
Just updated mine.
Main noticable things are:
- the new notification interface,
- the quick links page allows more icons and has better design, and
- Portrait mode on the camera.
What else called your attention?
Did a factory reset after install. Thought Asus cleaned up pretty well on Nougat for Zenfone 3 but the 3 Zoom's Nougat strips away almost everything. Apps could only get clearer if they replace Memo with Google Keep and not preload Duo.
I think there is more wall papers in wall paper slideshow.
Nougat ZenUI is much better than Marshmallow was.
Greatly appreciate the update. Yes, the UI is still terrible color and design, but Nougat makes this feel tolerable. Especially the ability to remove sooooo much bloat. Glad that I could finally get Google Phone dialer installed and working without the ASUS Call screen. Now if I could set long hold back button to kill I'd be quite happy.
Can you guys get me ota link ?
Use Android Terminal to Run this command
cat /data/data/com.asus.dm/files/tree.xml
Then upload tree.xml from your sdcard
Thanks
http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE553KL/UL-Z01H-WW-20.31.49.2-user.zip
Just looked at existing ROM links on their site and plugged in the new version number. TADA!

Interesting I'm still unable to install Google Phone (https://play.google.com/store/apps/details?id=com.google.android.dialer), stuck with ASUS's app.
Another one that bothers me is the Contacts app. I'm used to Google's stock and I find ASUS option way worse.
Ideas anyone?
I'm using google phone app on mine.
Download the Contacts APK from APKMirror.
http://www.apkmirror.com/apk/google-inc/google-contacts/
My camera app stopped working after the update :\ Even tried resetting it. Other camera apps work fine. Asus support says to reset my phone and otherwise send it in (for a software issue?!). I guess I'll be resetting, but this is the second time support told me to send in the device for a software issue. Can't say I'm impressed.

Strange display lag on Galaxy A20e

So I've noticed that my A20e has display input lag? The touches are are registered fine but the display seems like it doesn't keep up.
I went in a retail store to see if other a20e's are doing it and yes they do...the other models (a10 a30 etc.) DON'T have this issue....
How is the response on the regular A20 and is it a hardware or a software?

A20 response is very good.
I have no problems with it.
I am having the same problem, it's probably a GPU driver problem, if you change the video render to vulkan it stops hanging.

yes you can find this option under hardware acceleration on developer settings. Depending on the GSI you are using this option is not available, for example Lineage 17.
@demonic8383 I just remebered, you can turn off all of the system animations.

Yes
Accessibility, visibility enhancements, remove animations.
Makes it much faster.
So i searched in developer options to change the renderer but on Stock ROM there is no such option (
Tried to disable the animations and etc - no change at all (
Maybe when Samsung release a update for android 10 the issue will be resolved....

Thank you for contacting the Samsung Members team, it is a pleasure to attend you Mr. Krastev.
We need a detailed explanation of the situation.
If the delay comes when you are turning on the phone, or going back from stand by it is normal, since the display uses a new technology that consumes a lot of resources, so, the display can take until two seconds to respond during this 2 scenarios.
We recommend to close all the apps, and see if the phone is still slow, in such case, the phone has a system error, and you could perform a Factory reset, otherwise, the reason of slow speed comes from your apps usage.
Another thing to consider is your storage available space, since the phone needs some available storage space as virtual memory, the less available storage space, the less speed, please check you storage available space, if you have little space, please move your files to the SD card or to your cloud to free up space.
You need to be sure your phone has the latest updates, cause this situation could come by a lack of updates.
If the speed of the phone is slow in general, during all the operations with it, the phone could be facing a system error, which should be solved by performing a factory reset as follows:
Go to: Menu > Settings > Accounts & Back up > Samsung cloud > Back up this phone > Back up.
Next step is to remove your accounts, firstly the Samsung account and secondly the Google's account.
Then you can perform the Factory reset by going to:
Menu > Settings > General management > Factory reset.
After this, you can set your Google's account, then your Samsung account, and then you can go to menu > settings > accounts > Samsung account > restore data, to retrieve your backed up data.

You could try to debloat using titanium backup.
