Type inxi -h (then press ENTER) for extensive help on how to get the information you want. If the results scroll past one screen just use swipe up to scroll up, if you are in a Termux shell. You can copy and paste from within the Termux terminal, in the usual manner, to any paste data into other app on the device, including browsers. This will allow you to post information to forums, tech support, or customer service agents. You can also try addition information gleaning commands suggested by linux savvy tech support ppl.

There are a whole lot of other options to determine 'real' hardware and software details of an Android device from within Termux, and other linux style terminals/terminal emulators. You can even install additional packages within Termux. For more info just search for Termux using your favourite browser and search engine (most ppl use Google as their search engine but there are better & safer options like DuckDuckGo or even Yahoo among others).

If you are at all familiar with linux, Termux has a package manager that is pseudo apt. The command is pkg and it has the usual options one might expect from apt like install, search, show, list-installed and uninstall and more, as well as the -y for 'yes to all' argument.

If you're comfortable with the command line here's a better and simpler way that doesn't require adb and connecting to a computer, doesn't require root access or anything tricky. Easy for a novice or total noob:

Termux is a modified version of Linux.

inxi is a command line system information script built for for console and IRC. It is also used for forum technical support, as a debugging tool, to quickly ascertain user system configuration and hardware.

Termux also has the df and dh commands which show the real space used and available.

df -h (disk free, human readable output)  du -h (disk used, human readable output)

Here's the results from the inxi command on my Chinese tablet:

.../data/com.termux $ inxi CPU: single core AArch64 (-UP-) speed/min/max: 871/286/1508 MHz Kernel: 3.18.79 aarch64 Up: 9h 37m Mem: 1.4/2.75 GiB (50.9%) Storage: 39.75 GiB/Total N/A Procs: 2 Shell: Bash inxi: 3.3.31 .../data/com.termux $

The device reports 1TB of storage, 16GB RAM and Android 13 via the built-ins (Settings/System/About). Whereas it actually has 3GB RAM 25-30GB storage (depending on measuring methods/standards) and Android 8.1.0.

Termux is a terminal emulator with a modified version of linux.

inxi is a command line system information script, built for console and IRC. It is also used for forum technical support, as a debugging tool, to quickly ascertain user system configuration and hardware.

Termux also has the df and du commands which show the real disk space available (free) and disk space used.

df -h (disk free, human readable output) 

du -hs (disk use, human readable output & summary)

The 2nd command example du has a couple of switches:

-h is used to show file sizes in human readable format just like df, i.e. KB, MB, GB

-s is to show a summary only. This is necessary to stop du from displaying the name and size of every file. Instead it displays only a summary, which is the size of all files - the summary of disk use. Try just du and see what you get.

du --help => Summarize device usage of the set of FILEs, recursively for directories.

df --help => The "disk free" command shows total/used/available disk space for each filesystem listed on the command line, or all currently mounted file systems.

.../data/com.termux $ inxi
CPU: single core AArch64 (-UP-) speed/min/max: 871/286/1508 MHz Kernel: 3.18.79 aarch64 Up: 9h 37m Mem: 1.4/2.75 GiB (50.9%) Storage: 39.75 GiB/Total N/A Procs: 2 Shell: Bash inxi: 3.3.31
.../data/com.termux $

The actual output from inxi displays better than it is shown here, much more readable.

My device reports 1TB of storage, 16GB RAM and Android 13 via the built-in Settings / System / About. 

Whereas it actually has 3GB RAM 25-30GB storage (depending on measuring methods/standards) and Android 8.1.0. which is mostly evident from the inxi output.

If you're comfortable with the command line, here's a better and simpler way:

1. Install F-Droid from Google Play
2. Install Termux from F-Droid
3. Run Termux
4. Type pkg install inxi -y, then Press ENTER
5. Type inxi, then Press ENTER

Explanation

F-Droid is an alternative to Google Play. It says it is an

installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform.

Termux is a modified version of Linux.

Termux combines powerful terminal emulation with an extensive Linux package collection.

inxi is a command line system information script built for the console and IRC. It is also used for forum technical support, and as a debugging tool, to quickly ascertain user system configuration and hardware.

**You might be able to skip installing F-Droid and just install Termux from Google Play... try it.

I had the same issue and wanted to check my hardware because I suspected the hardware and software were spoofing the information shown by the built-in Android tools (Settings) and other apps like AIDA, CPU-Z, Device Info HW, and other common apps. I was right (grrr 😖)

Termux also has the df and dh commands which show the real space used and available.

• df -h (disk free, human readable output)
• du -h (disk used, human readable output)

Type inxi -h (then press ENTER) for extensive help on how to get the information you want. If the results scroll past one screen, just use swipe up to scroll up, if you are in a Termux shell. You can copy and paste from within the Termux terminal, to any other app on the device, including browsers. This will allow you to post info to forums, tech support, or customer service agents.

There are a whole lot of other options to get the real hardware and software details of an Android device from within Termux, and other Linux-style terminals/terminal emulators. You can even install additional packages within Termux.

And I'm 100% certain I've been cheated.

*Note: I also used 'Root Checker' to check the version of Android. Install Root Checker from Google Play, launch it and click VERIFY ROOT. It will display a message telling you if the device is rooted or not, plus some other info including the actual OS and its version.
