You can easily uninstall, disable or remove the pre-installed system apps on your Samsung Galaxy S9 or S9 Plus by executing the commands mentioned below. All you need is to install ADB and Fastboot tool on your computer and the name of the app’s package name you want to uninstall. This method works on all Samsung devices.

1. Download the setup ADB and Fastboot on your computer.
1. Windows
2. Mac
3. Linux
2. Enable USB debugging on your phone by going to Settings> Developer options.
3. To know app package names for the apps installed on your Galaxy S9, install App Inspector from the Play Store. 
   App InspectorPrice: Free

   





4. Note down the app package names on a notepad app for future reference.
5. Connect your phone to the computer and ‘Allow USB debugging’ if prompted.
6. Well, now launch a command prompt window. To do so, place the mouse pointer on the Windows icon and do a right-click on the mouse. Select the Command Prompt option to launch the cmd window.
7. Now type the following command in it and hit the Enter key.

   adb shell

   
8. On hitting the Enter key, you’ll get the codename for your device (‘starlte’ for the Galaxy S9 and ‘star2lte’ for the S9 Plus).
9. Now issue the following command (pm uninstall -k –user 0…….) followed by the app package name (To See Packages: pm list packages / pm list packages -f / pm list packages | grep X) and press the Enter key. In the following command “com.samsung.android.messaging” is the app name for Samsung’s stock message app.

   pm uninstall -k --user 0 com.samsung.android.messaging

10. Just keep executing the above command with the app package names of the system apps you want to disable until you have removed all desired apps.

install pygraphviz on windows 10

1. Download graphviz-2.38.msi from the graphviz Graphviz site https://graphviz.gitlab.io/_pages/Download/windows/graphviz-2.38.msi
2. Install the msi (I used cmd with Admin priviledges)
   msiexec /a graphviz-2.38.msi
3. For some reason this doesn't add Graphviz to your system path, so you need to do that manually. For me this was
   SET PATH=%PATH%;C:\Program Files (x86)\Graphviz2.38\bin
4. I then had to get a specific Windows pygraphviz wheel from this really useful site, specifically pygraphviz-1.3.1-cp34-none-win_amd64.whl https://www.lfd.uci.edu/~gohlke/pythonlibs/#pygraphviz
5. Once I had this I then installed it using pip/mingw32 to my virtual environment
   $ pip install pygraphviz-1.3.1-cp34-none-win_amd64.whl

Disable swapping

macOS tends to swap memory to disk when there are still tons of free memory available. Swap, aka. virtual memory, is disk-based and thus it is terribly slow, even on a lightning fast SSD. Disabling swap is absolutely fine, as long as you keep the number of running applications low.

When swap is disabled, macOS will try to utilize as much free memory as possible and won’t complain at all until under extreme memory pressure. When it does under pressure, kernel panic will follow. So keep an eye on memory pressure and you will be fine.

There are a number of different modes that macOS manages its memory. In vm_pageout.h:

#define VM_PAGER_DEFAULT                        0x1  /* Use default pager. */
#define VM_PAGER_COMPRESSOR_NO_SWAP             0x2  /* In-core compressor only. */
#define VM_PAGER_COMPRESSOR_WITH_SWAP           0x4  /* In-core compressor + swap backend. */
#define VM_PAGER_FREEZER_DEFAULT                0x8  /* Freezer backed by default pager.*/
#define VM_PAGER_FREEZER_COMPRESSOR_NO_SWAP     0x10 /* Freezer backed by in-core compressor only i.e. frozen data remain in-core compressed.*/
#define VM_PAGER_FREEZER_COMPRESSOR_WITH_SWAP   0x20 /* Freezer backed by in-core compressor with swap support too.*/

By default, in-core compressor with swap backend, or VM_PAGER_COMPRESSOR_WITH_SWAP, is used. You can verify this by the command below:

$ sysctl -a vm.compressor_mode
vm.compressor_mode: 4

Mode 0x1, VM_PAGER_DEFAULT, turns off memory compressor and swapping, which is proved to be harmful to the system stability. Modes 0x8, 0x10 and 0x20 are the so-called “freezer” modes, which “freeze” the OS instantly when memory is under pressure. You don’t want to try them.

Mode 0x2, VM_PAGER_COMPRESSOR_NO_SWAP, is the best choice here. It provides memory compressor with swapping disable. In other words, when memory is under pressure, macOS will try to compress the active but non-wired memory, thus freeing part of the memory back to the system. macOS uses WKdm algorithm to compress and decompress the memory, which is fast and battery-efficient. Yet, kernel panic is still possible if there is no more compressible memory.

To change from mode 0x4 to 0x2, use this command and reboot:

$ sudo nvram boot-args="vm_compressor=2"

When using mode 0x2, memory pressure must be monitored closely to avoid kernel panic. Once the compressed memory grows close to 50% of total memory capacity, you would either like to close some of the running applications, or simply reboot the system.

Disable System Integrity Protection (SIP)

You need to disable parts of SIP for the above to work while leaving others enabled.

If you run csrutil status, even while booted normally, you will see the component parts of it. Each of these can be selectively disabled by running one of the following commands while booted into Recovery mode:

• csrutil enable --no-internal
• csrutil enable --without kext
• csrutil enable --without fs
• csrutil enable --without debug
• csrutil enable --without dtrace
• csrutil enable --without nvram

You can disable two or more components by structuring the command as follows:

• csrutil enable --without kext  --without debug
