Allwinner A23 Android 4.2.2

Hi again,
I don't know if I reported this before, but I discovered that the touch screen issue only exists when the system is booted up. It does not exist in recovery mode, i.e. the touch screen works in recovery but not when the system is fully loaded.
I also found that a mouse, attached to the usb port, works when the system is fully loaded. (I haven't tried to see if it works in recovery.) This means that I can do everything, using the mouse, that I was able to do when the touch screen was working.
This, to me, suggests that the problem is software related.
One, online site, suggested that one of the many possibilities for the screen not working, could be a virus. However, I have not been able to find a (free) antivirus software that I can download and install, which will work on this system.
Any suggestions are appreciated.
Here are the system specs:
Processor: dual core A23
Model number: Q8H
Android Version: 4.2.2
Firmware Version: 2.0.8
Kernel Version: 3.4.39 android 10@Linux2 #304
Wednesday March 26 18:37:10 CST 2014
Build Number: polaris_eng 4.2.2 JDQ39 201 40326 test-keys

For Adoptable storage Fast random WRITE speed or fast random READ average good speed values?

A nand image of the sd card won't get you anywhere, as a new key is generated as part of the factory reset process, and is stored on the phone in a secure partition.
Here's a guide to SD card speeds: https://www.kingston.com/unitedkingdom/en/solutions/personal-storage/memory-card-speed-classes

I wouldn't bet on an SD card lasting 5 years if used as adoptable storage. The only justification is if the device has low storage capacity.

Help Ringtones malfunction on Samsung A10s

Good evening!
The Samsung A10s cell phone, after the newest updating to install Android 11 and One UI pack, had a horrible sound, a lot of hisses, it sounded like amateur radio. The only solution was to downgrade until Samsung releases a decent patch for this update.
However, after the downgrade, the device's default ringtones disappeared almost all, and the option to test the few ringtones that were left does not exist. I need to choose a ringtone and wait for someone to call me to find out what the ringtone is like.
I downloaded a ringtone in mp3 and put it in the Ringtones folder, and the sound manager lists the file, but it also doesn't allow testing, I have to choose and wait for a call... it's ridiculous, isn't it?

I ask you: which Android system app tests the sound of ringtones before applying? might it be locked after the downgrade?
Is there any website where I can find the default A10s cell phone ringtone pack to manually put in the Ringtones folder?

HK Variant

Hong Kong N20U variant.
Does anyone know if updates for Hong Kong Snapdragon variant are available in the UK?
Thanks for any replies.

That's the variant of Note20 Ultra I've got, although mine was purchased directly from Samsung here in mainland China, rather than HK SAR.

It should receive updates no problems in the UK, and I've had other China version phones receive updates while they were in the UK. You can check if you already have the latest update from Samsung, by seeing if it's got the July 2021 security patch level or not.

How to infuse/push/install busybox SU in twrprecovery.img for getting root previlages commands

**Question :How to infuse/push/modify/install busybox SU in twrprecovery.img for getting root privilages commands**

I want to take backup restore flash change some PM Package management and SM storage Management settings of my android 5.1.1 /6.0 mobile phone through adb shell commands or through twrp terminal without installing twrp or SU or rooting mobile device



1. Firstly I want to take backup of mobile system.img userdata.img through adb pull command and then recover write back adb push

My concerns related to first :

a. As adb pull reads and copy data but adb push writes on the device
b. Will adb push work without rooting mobile phone without root privilages.
c. If phone bricked or something gets wrong while rooting and phone is not rooted then will adb push work or not.

Code:
    Steps of commands using for backup of device
Adb devices
adb reboot bootloader
adb pull /dev/block/mmcblk0 mmcblk0.img
Adb push mmcblk0.img /dev/block/mmcblk0 mmcblk0.img


2. Using PM package manager on unrooted mobile android 5.1.1 with following commands but error


Code:
Adb devices
adb reboot bootloader
adb shell pm set-install-location 2
adb shell pm get-install-location

Error of command
/sbin/sh: pm: not found

what I understood from above error means that PM binary command file is not available in /sbin/sh/ folder as phone is not rooted so what I think if I put these binary files or install busybox within twrprecovery.img before loading and run temporary pm command so that I don't have to root the device and temporary set the changes in device.

If it's possible then kindly share the link for step by step procedure
for modifying twrprecovery.img before booting in pc computer windows as I am new novice to adb shell Linux commands

3. Thirdly As whenever I run SM storage manager command adb shell following command on unrooted android 6.0 mobile from it gives following errors


Code:
Adb devices
adb reboot bootloader
adb shell sm has-adoptable
adb shell sm set -force- adoptable true
adb shell sm list-disks adoptable
Adb shell sm partition disk:179:160 mixed 25
adb shell sm format private:179,3
adb shell sm mount private:179,3

It gives following errors

/sbin/sh: sm: not found

what I understood from above error means that SM binary command file is not available in /sbin/sh/ folder as phone is not rooted so what I think if I put these binary files or install busybox within twrprecovery.img before loading and run temporary pm command so that I don't have to root the device and temporary set the changes in device.

If it's possible then kindly share the link for step by step procedure for modifying Twrprecovery.img before booting in pc windows as I am new novice to adb shell Linux commands

4. Now if boot in fastboot mode and run twrprexovery.img or cwgmod recovery.img with these commands and then in twrp or cgmod terminal windows can I run busybox or Super user or PM SM command


Code:
Adb devices
Adb boot bootloader
Fastboot boot twrprecovery.img

5. Secondly the whole ideas is that I want to virtually temporary use twrp terminal with busybox or Super user binary to execute services packages like PM (package manager) SM (storage manager) within from twrp recovery menu terminal (loaded in fastboot boot twrprecovery.img mode). Or adb sideload If it's possible technically feasable. If yes then can we modify twrprexovery.img and infuse insert busybox in it before loading or after loading.

6. Thirdly I don't want to install twrp or busybox or any super user binary file inside mobile device and don't want to install anything inside mobile except the changes alteration of settings done after execution of SM PM commands. That is I want to execute PM SM from within twrprecovery.img temporary and make alter changes virtually not hampering mobile device files

I smashed my phone today

Reminds me of a story that I'll hide since it's not quite on-topic...

A man had just collected his change from a convenience store purchase and went to the men's room to freshen up. It was his habit to always check his change, as he would occasionally find an old or valuable coin.

He stood at the urinal, doing his business as another guy at the adjacent urinal did his. Thinking he could easily multi-task, he noted an old coin and remarked, 'wow, this thing is old! I wonder if..." but then fumbled - and right into the urinal it went. And there it lay, getting rained on. The guy next to him waited to see what he would do.

The man finished his business, pulled out his wallet and removed a $20 bill. The next guy watched in amazement as the man dropped the $20 bill into the urinal, and then reached in to retrieve both the bill and the coin. He then turned to the guy next to him and said,

"You didn't think I was going to reach into that just for a coin, did you?"

:D

Veterans

Okay, here's another awesome veteran story: in January 1941 Whitney Duhon left his Abbeville, Louisiana high school in his sophomore year to join the war effort in Europe at age 16. In a recent interview, he lamented that his one regret in life was not finishing school.

On Monday, August 9th, 2021, at the Franklin County Tennessee School Board meeting, Whitney Duhon was awarded his high school diploma... at age 96. It was a privilege to be involved in something like this.

App for hanging off Whatsapp after a selected time of a Videcall

Howdy. English is not my main language, but I'll give it a try.
I'm looking for an app that could be used to hang off a videocall while using whatsapp.

The use of this app would be to have a video call, and it would end automatically after a lapse of time I previously have selected (cause I fall asleep), so my phone won't dicharge because of the videocall, but stays turned on for the alarms to work.

Thanks : )

Trying to put NoRoot Firewall apk on sd

The only reason I was using a Chromebook at the library was to install NoRoot Firewall on the sd card. Somebody else got it out of the old phone (barely) and I put it in an adapter and thence to the slot in the computer. I clicked or tapped or whatever on it to make sure it was the real deal, and that's when I got the message about how it could not be opened by anything the laptop had. I guess it'll still work in a new phone though. I hope to have one later today. The old one is that Moto G Stylus that is still apparently stuck in fastboot and I don't even know how that happened. Another mystery is how it still has the energy to show that when it has not been plugged in for more than a month.

Can I Keep Ringer Working Overnight?

I need a way to let phone calls ring any time, without any other notifications doing so.
I have the option of allowing phone calls to go through, even the option of limiting them to my contacts, while silencing all other alerts. I leave it off, so I haven't played with it, but it also appears I can exempt certain apps from the DND as well.
