Why different file size Adb pull vs twrp data image size of userdata.img

Question Why different file size Adb pull vs twrp data image size of userdata.img

In my lyf water 7 mobile device having 16gb internal memory and 2 gb ram and 16gb external sd card

I had first factory rest my mobile with and formatted my external s d card with no user apps or data installed then I decided to root it and before that want to take a backup

I had loaded twrp recovery (fastboot boot twrprecovery.img) in bootloader mode and took NANDROID backup of system boot cache userdata through twrp backup menu and through adb pull tool all partitions backup of mmcblk0 and system boot recovery userdata and all in other partitions in devices.

Now the backup image size of data taken by twrp in ext4 file system is 2.5 gb whereas adb pull in pc fat32 created file size of 13.5 gb. I think it created file for empty sectors to why both file size of same partition backup is different

Is there any parameter syntax of adb pull way to compress or not trim or not to take empty sectors backup or compres file

I had founded a command "adb shell dd if gz" to compress file but it can't be flashed by fastboot flash command. Is there any way to manually create a flashable compressed file through adb pull or ignore empty space while creating NANDROID image backup so that small file created which can be stored online or in flash drives easily.


Summary brief to clarify
I mean to say that as in same newly formatted factory reseted mobile device (10gb of android system files 16gb of total rom) partition when i took twrp backup datatwrp(ext4).img (as it took file backup image) is compressed to of 3.4 gb (10gb android os system files) and the same device data pulled by adb pull .../mmcblkp30 userdata.img (which creates partititon image backup) image created is of 13.5 gb (10gb out of toral 16gb rom) so the be adb pull userdata.img image file size (13.5gb) is more than the data files size inside internal rom can we decrease that backup size either by zero filling (unused space) or triming the empty space of internal memory or any parameter in adb pull command compresion tool (like gz) can be used with by adb pull command

File Browser and Long File names

Yes, my Linux desktop has a wired internet connection, but no wireless connection. Also, my android device is a tablet: it has no cellular connectivity. It has WiFI, but I don't use it.

Anyhow, I'll weigh my options. I was not planning on downloading apps and entering the modern world, but I might. Or, it might be easiest to simply rename the files. Thanks again for providing options.

Renaming the files is an option.

However, the apps suggested are sure to enhance your Android experience.

Everything on that device is run from an app.
All you are doing is increasing its capabilities and therefore your enjoyment of it.

That is the beauty of Android.

Another option is to go to your local library- free Wi-Fi.

Also, most fast food places, Wal-Mart, laundry mats, etc.
I even set up my latest device in Wal-Mart's parking lot, using their Wi-Fi for a connection.

How to bring"Move app to SD card" option hidden missing in android 5.1.1 app2sd link2sd giving error

It is not really that way.

A 'burner phone' is a phone that is usually locked to a single cellular provider for a year or so.
The phone is bought at a great discount because of this.

In this way, a person with little money can have a decent phone.

You do not reallt rent it, but pay for minutes/data periodically.

After the year or so is up, you can have the provider unlock the device for you.

The drawbacks are that these devices are usually 1-3 model years old, and so by the time the term is up they are even more out of date.

The good news is that you can buy one and never pay for anything more if you only use the device on Wi-Fi.
@ocnbrze bro okay but in India I don't think cellular companies provide such service they sell Chinese phone with their brand name I have to purchased 5 year before this mobile lyf water 7 (the mobile device I asked in question)from Jio India as they were giving free unlimited 4gb as launching offer for first 6 moths but mobile config is no ot much but they cost high 8k -12k

Help android-x86_64-8.1-r6/VirtualBox 6.1.26/Ubuntu 20.04LTS Linux PC : several problems to use Android

Hello !
I installed android-x86_64-8.1-r6 on VirtualBox (on an Ubuntu 20.04LTS Linux PC) and I'm looking to install an APK on it.

I have several problems:
  • the keyboard is perceived by android-x86_64-8.1-r6 as a qwerty (I have a bépo) and I don't know how to change that the interface which currently is in command line (see attached image),
  • I would appreciate having a graphical interface: does it exist?
  • If so, how to get it?

The keyboard is configurable within the running Android OS itself via the Settings option, and it is graphical.
  • I don't know how to install my APK and once this APK installed it will need to access the sound and the Internet network from the PC, how could it happen?

Does the virtual Android OS have internet access? If so you could email yourself the APKs, or uploaded them in the cloud, like Google Drive, and download them within Android. The other way is to use the share options within Virtualbox and share a folder to the Android OS. The sound settings are configured via Virtualbox.

Rooting for Data Recovery?

Hello forums,

This is my first post, I have created this account for a specific purpose, I hope you can help me :)
I have realized that there are some photos and videos that are very important to me that were deleted from my phone and have been deleted from my google photos around July 2020. I wanted to try these data recovery tools but they require root- which would wipe my phone, correct?

I would do anything to retrieve these files... I did not know they were important but now I realized they were extremely important to me. It is my fault, but I would try any solutions you have to offer. How do I root without losing my data?

Thank you... :)

That was well over a year ago, and if you've been using the phone since then, it's extremely likely the deleted data would have been overwritten, and thus impossible to recover.

Help WHATSAP deleted and botched restore

I expect that the audio stuff should be in the WhatsApp media folder, probably in the either the WhatsApp Audio or the WhatsApp Voice Notes subfolder.

I don't know the app, and am of course suspicious of recommends from their own website (you also get people who pop up in forums to recommend some app, whose entire posting activity seems to be recommending such an app, which I'm also very suspicious of). But it sounds like anything might be worth a shot.

trying to pair PC with J3 via Bluetooth

Again,Thanks to all. OK on that link you gave me for Android, puppykickr. The main NitroShare website did not show that, maybe I did not look good . . .
But . . . guess what ! After dealing with the company who files I was trying to transfer from my PC to phone via Bluetooth . . . they tell me . . . oh you can simply go to the Google Play Store on your phone and simply downlard our software into your Android ( phone ) device directly . . . heck I said ???
Here their telling me to do it via Bluetooth or USB cable . . . when I could have AND DID do it directly from the Internet to my phone . . . it worked. I was in the WI-FI mode on my phone and it downloaded the software perfectly and the thing works. No Bluetooth or USB cables involved.
I'll still mess with the Bluetooth, just to see if I can get it to stay connected, someday I'll do that !!!
Again thanks to you all and Take care,
Al

Datepicker problem

I have a problem setting a date() at the datepicker item at my activity ,I use the bellow code and the date does not apply at DatePicker, what is wrong ?
Date date = myapp.getAdate();// the date instance
Calendar cal = Calendar.getInstance();
cal.setTime(date);
DatePicker picker=(DatePicker)findViewById(R.id.datePicker1);
int year=cal.get(Calendar.YEAR);
int day=cal.get(Calendar.DAY_OF_MONTH);
int mnth=cal.get(Calendar.MONTH)-1;
picker.init( year, mnth,day,null);
[EDIT] I noticed that the problem is the date that I set -> cal.setTime(date);
How I have to set the date, it has the format dd/MM/yyyy
