Debloating methods

There are 3 methods of debloating I've used at the moment : Delete, freeze & pm uninstall.

Delete

Deleting with TWRP / any other TWRP-based recovery of choice : (Not sure about TWRP-based ones, so this assumes you're using TWRP) (Also, be careful not to delete the entire app folder, or you'll have to reflash your ROM)

1. Boot to TWRP / any other TWRP-based recovery of choice. As long as the recovery has read/write access to the partitions, you're good to go.
2. Enter the Mount option, tick System, as well as any partition you'd like to debloat, like Product & Vendor. Again, make sure these partitions aren't read-only.
3. Head to Advanced > File Manager.
4. In the file manager, browse your way to the corresponding folder of the app you'd like to delete.
5. In that folder, select the folder logo on the bottom right corner & select Delete. Follow the prompt.
6. Wipe Dalvik & cache before booting to system after you're done debloating.

Advantages:

• Doesn't require root access
Simply enter TWRP / TWRP-based recovery.


• This method is the only one to allow you to potentially regain a few extra bytes of internal storage from the system.

Disadvantages:

• Debloating (and / or system app replacements) doesn't persist across dirty flashes
I could pass this off as a minor issue since I clean flash all the time. However, for those who uses OTA updates, this could be a problem for them.

Freeze

For apps that can be frozen from Settings, enter Settings > Apps & notifications > see all apps. Then, browse to your app to freeze, & select Force Stop, then Disable.

Otherwise, use SD Maid with root access. After granting SD Maid its needed permissions (root (if Magisk is flashed into the system), storage, usage access), enter Settings > AppControl & tick "Include System-Apps". Afterwards, enter AppControl, select Scan, & browse to the app you're freezing. Select Force Stop application & Freeze app.

Advantages:

• Debloating process persists across dirty flashes
This means that whenever you're doing OTA updates, you don't have to debloat again.

Disadvantages:

• SD Maid needs root access for this approach
• Without SD Maid & root, this method cannot be applied to all system apps.

pm uninstall

pm, which is another shorted word for package manager. The classic uninstall method that also works on non-rooted PDAs (ADB), and the common method to temporarily debloat some stock ROMs.

In order to do this via ADB, enable USB debugging on your PDA. Then, connect it to your PC. On the PC, open terminal / command prompt / PowerShell, navigate to the folder containing adb/fastboot tools (may not be necessary on Arch distros if android-tools is installed), type adb devices to detect the PDA & trigger ADB prompt in the PDA, which you need to accept in order to proceed further. Afterwards, enter adb shell, & pm uninstall --user 0 (package name).

Alternatively, you could also do this by using a terminal emulator in your PDA, but you'll need root as well. To do this, open your terminal app (install it beforehand if you haven't), type su to gain root, & pm uninstall --user 0 (package name).

General advantages:

• For terminal users, the experience of typing commands.
• Works on both stock & custom ROM

General disadvantages:

• You'll need to know the package name of the app you want to uninstall
For example, you can't just type pm uninstall --user 0 Phone - it's pm uninstall --user 0 com.android.dialer

Advantages (ADB / PC terminal):

• No root access required for the PDA
• Generally faster command typing, since you'll be using an actual keyboard

Disadvantages (ADB / PC Terminal):

• Requires a PC with ADB / fastboot tools & USB cable to connect PC & PDA
• Requires you to turn on USB debugging, which may re-enable itself on boot if it's disabled by default (this depends on the ROM)

Advantages (root / PDA terminal):

• Doesn't require you to enable USB debugging & risk it re-enabling itself on boot
• You can do it on the go, no USB cable necessary (unless you have to charge of course)

Disadvantages (root / PDA terminal):

• Your PDA has to be rooted
• I find typing on a PDA to be far slower & not as satisfying (if at all), but this one's subjective.

• Contacts - com.android.contacts

Location : /system/priv-app/Contacts (Pie) | /system/product/priv-app/Contacts (A10)

Remove / freeze only if not using the PDA as a phone.

On Android 10 it can be safely removed / frozen in all custom ROMs. However, may trigger RescueParty on Pie Lineage / GZOSP ROMs.

On PDAs with dynamic partition (such as Poco X3N), disabling its on-boot service / removing / freezing may cause the PDA to get stuck in boot-animation.

• Phone Services - com.android.phone

Location : /system/priv-app/TeleService

On Android 10 it can be safely removed / frozen in all custom ROMs. However, may trigger RescueParty on Pie Lineage / GZOSP ROMs. If removed / frozen, may cause Bluetooth to not function (keeps stopping when enabled).

On PDAs with dynamic partition (such as Poco X3N), disabling its on boot service / removing / freezing will cause the PDA to get stuck in boot-animation.

I don't recommend removing / freezing this unless you're absolutely sure you know what you're doing, & do it only on a PDA that you won't use as a phone.

• Phone & Messaging Storage - com.android.providers.telephony

Location : /system/priv-app/TelephonyProvider

On Android 10 it can be safely removed / frozen in all custom ROMs. However, may trigger RescueParty on Pie Lineage / GZOSP ROMs. Will not cause PDAs with dynamic partition to get stuck in boot-animation if removed / frozen.

I don't recommend removing / freezing this unless you're absolutely sure you know what you're doing, & do it only on a PDA that you won't use as a phone.

• Call Management - com.android.server.telecom

Location : /system/priv-app/Telecom

On Android 10 it can be safely removed / frozen in all custom ROMs. However, may trigger RescueParty on Pie Lineage / GZOSP ROMs. Haven't tested if removing / freezing this will cause PDAs with dynamic partition to get stuck in boot-animation.

I don't recommend removing / freezing this unless you're absolutely sure you know what you're doing, & do it only on a PDA that you won't use as a phone.

• qcrilmsgtunnel - com.qualcomm.qcrilmsgtunnel

Location: /system/priv-app/qcrilmsgtunnel (Pie) | /system/product/priv-app/qcrilmsgtunnel (A10) | /system/system_ext/priv-app/qcrilmsgtunnel (A11)

Not sure what this app does.

On Android 10 it can be safely removed / frozen in all custom ROMs. However, may trigger RescueParty on Pie Lineage / GZOSP ROMs. For A11 (especially for PDAs without dynamic partition), it may be safe to remove on the 1st boot to recovery from a clean flash, otherwise the PDA's stuck in boot-animation.

I don't recommend removing / freezing this unless you're absolutely sure you know what you're doing, & do it only on a PDA that you won't use as a phone.

• Dynamic System Updates - com.android.dynsystem

Location : /system/priv-app/DynamicSystemInstallationService (A10, A11)

Probably allows the Play Store to force the "no reboot" updates in the background. Safe to remove / freeze on A10. For A11, it's safe to remove only in the 1st boot to recovery (after a clean flash) if not using Play Store.

Will cause PDAs with dynamic partition running A11 to get stuck in boot-animation if removed / frozen.

Google

Go-ogle apps available for Goolag variants of ROMs. You shouldn't encounter these in Vanilla ROMs, but some soydevs (especially Limbo devs, but others might) might put it there.
