Help Running Android x86 on Centos 7

Hello, I'm trying to run Android OS on a centos VPS following this tutorial:
Code:
[url]https://dev.to/gauthamp10/easiest-way-to-install-android-os-via-linux-no-grub-fiddling-3gao[/url]
I've done all this via ssh with no remote desktop access, after the installation i have a Android directory with various files in it.

Then it says
Volá! Now you are ready with android x86 desktop O.S.
Reboot and you will see a boot entry with Android x86 tag

So I've rebooted and logged back in via ssh but its still on centos, i did not see any boot entry with Android x86 tag, although I'm sure I'm doing something wrong.

I'm not sure where to go from here to get android working.

Storage manager (SM) Partitioned Micro sd card but how to mount the extended partition

Question:- Storage manager (SM) Partitioned Micro sd card but how to mount the extended partition and use it as internal storage.?

I purchased 6 months before, Samsung Galaxy s20 Fe with android 12 with 128 GB internal memory and a 128 GB external Micro SD card. I am an IT freelancer professional, so I have a job is for testing daily 1000's of different android apps some I have keep installed to create logged reports either monthly weekly or quarterly and my other work is to do some short video advertisements or photo editing and some other GPS technical official apps to do my job in an instant go while traveling.

I want to set default installation of apps location to micro sd card, i tried but it only moves the main APK files, leaving ODBB file like data, cache, lib, and dex in internal memory thus occupying space in internal memory. I want to keep my internal memory free for output files of video editing to fast rendering of photo editing or video editing file on mobile.

I have tried Adoptable storage ( formatting external micro sd card as internal) without rooting once in my android 6.0 Marshemellow and thought it may work in android 12.0.

i tried following commands in following sequence

Code:
adb devices
adb shell

r8q:/ $ sm list-disks adoptable
   Disk: 179,0 (output of list-disk adoptable command)
r8q:/ $ sm has-adoptable
      false
r8q:/ $ sm partition disk:179:0 mixed 40
r8q:/ $ sm set-force-adoptable true
r8q:/ $ sm list-volumes all
        private mounted null
        public:179,1 mounted 5C8A-85AC
        private:179,3 unmountable
        emulated;0 mounted null
r8q:/ $sm format private:179,3
r8q:/ $sm mount private:179,3
r8q:/ $ sm has-adoptable
      false
r8q:/ $ sm list-volumes all
        private mounted null
        public:179,1 mounted 5C8A-85AC
        private:179,3 unmountable
        emulated;0 mounted null

lrwxrwxrwx 1 root root  20 2022-11-07 13:12 shared -> /dev/block/mmcblk0p1

Result is fine with no errors, it partitioned the micro sd card and converted formatted and mounted my 128GB card to 2 parts ie.as in mobile phone settings>storage in android 12.0 its showing 47.63GB card after commands it means its mounted and the micro external card is parted 47.63 portable is showing. but second partition is not showing in android and the files apps moved is still saving in 47.63 gb public:179,1 mounted 5C8A-85AC not the other one which is private:179,3 unmountable and not being used and remaining 80.37 GB is unallocated and not usable

I rebooted my android phone twice still.

But internal its still showing 100GB remaining and its not added and why the remaining space partition of 80.37GB is its not showing in android device how to mount or show in GUI of android and how to now 80.37GB partition as adoptable storage or format remaining 80.37GB as internal memory and extend my internal memory storage and how to use the partition in micro sd card and remaining

i tried $sm mount private:179,3 to to mount 179,3 private sd card second parition but still its hidden and showing invisible

on command ls -al /dev/block/platform/soc/8804000.sdhci/by-name/
Code:
lrwxrwxrwx 1 root root  18 2022-11-07 13:12 mmcblk0 -> /dev/block/mmcblk0
lrwxrwxrwx 1 root root  20 2022-11-07 13:12 mmcblk0p1 -> /dev/block/mmcblk0p1
lrwxrwxrwx 1 root root  20 2022-11-07 13:12 mmcblk0p2 -> /dev/block/mmcblk0p2
lrwxrwxrwx 1 root root  20 2022-11-07 13:12 mmcblk0p3 -> /dev/block/mmcblk0p3

it showed 3 partitions of micro sd card ie /dev/block/mmcblk0p1 & p2 & p3 but how can we mount the undisplay partition by
mount /dev/block/mmcblk0p3 /data/sdext2 will it write in init.c so that its gets every time i reboot restart the android phone. by which command i can show the micro sd card hidden partition so that it can be displayed in settings-storage and works as adoptable internal storage

Thanks for giving time and reading my question and i will be obliged to get experts advice solution for my problem . Thanks a lot in advance for your precious time advice and knowledge sharing and help.

Android 12 update. AVJE. NOVEMBER security patch

Samsung have begun rolling out an update to stable users on Android 12. The AVJE release has the November security patch.

So far, the European models, F936B, are receiving this update.

Build date = 24 October 2022

Build no: = F936BXXS1AVJE

It is a FOTA, (Firmware Over The Air), update and you can check... Settings > Software update... to see if it is available for you. Alternatively, you can connect to the Samsung PC suite, Smart Switch and check via that.

As far as we know, the November roll-out date for Android 13 is still on.

Move file from Download to folder

Samsung A52 Android 12

Copied images from PC to phone. Images are in Download. I want to attach images to Text Message. But in Download they are not available to send via text or email. So I want to move or copy from Download to an accessible folder such as Photos or Gallery. But can't find any menu options to move, send, copy or drag & drop to a folder of my choice.

Share doesn't work on same phone. Google search found that inability to move files from Download is a common problem. None of the suggested answers will work in my case. I'm an experienced user. I can move files from folder to folder. Why is it so difficult to move a file from Download storage to another folder on the same phone?

PS___Image files are in PDF format. I can view the images, but Download won't allow me to open the file in Acrobat

Problem with wifi and audio

Hello everybody,
I bought a Samsung Galaxy Z Fold 3 last year.
Until August 2022 I have never had any problems.
Then now it is not possible to enable wifi and when I open it the audio no longer works.
I called Samsung about the warranty and they told me it's not covered by the warranty for them because it has a small mark
in a corner of the smartphone, absurd.
So since I am an IT and electronic technician and I have already repaired Iphone in the past, I am trying to repair it myself.
Also because to repair it out of warranty they asked me for 600 euro.
I have already opened the back cover and checked the various flex cables.
I wanted to ask you if there was a Fold 3 hardware expert among you, I mean that he knows the various components.
for example for the wifi problem that does not enable what should I look at exactly, does it have its own board or a flex cable that I can replace?
For audio not working when I open it here too maybe it could be a flex cable problem.
I have yet to open the main display to see the other components.
Let me know if there is any expert.
Thanks
