[TouchPad General] HP_TOUCHPAD:
The main issue with the Tablet is the low amount of free RAM (Memory), which is about 650 MB.

If the App does not have enough RAM to start it will crash or not launch at all.

The Custom Android ROMs provide the basic, but it can be reduce to get some extra RAM as every single Byte makes a difference.

Reducing the Operating System is done on every device it will allow for a light and faster experience on older hardware.

On new versions of Android the installation is provided in a file system.new.dat.br, is a compress image that contains all the Android system files.

The file can be uncompressed to remove features and Apps and then repack to flash, but it requires a PC and the process is very complicated, take a look on how is done:

Guide on how to :[Tool]Extract and Repack system .DAT/BR and .IMG on android 5-8.1

The flash files provided in this guide will Reduce the ROM by just flashing a file which takes seconds, no PC required and the user does not need to do anything.

The ROM does not get modify in anyway and it can be restore to its original install if need it.

Features that does not get Remove if the ROM provides support for the hardware:

WiFi

File Manager

Bluetooth ( Removed in ROMs that does not support it )

Camera and Gallery ( Removed in ROMs that does not support it)

Any Variant of Open Gapps works and also the Play Store.

The process is the same for all listed ROMs from this guide:

system/media/audio Apps needs to be move to system/priv-app

The App or feature will be install at boot time.

ROM_Restore:

Moves the previously Apps to its original location, if the user wants to have all the ROM Apps.

system/media to system/app

system/media/audio to system/priv-app

Completely delete the files in the following location.

system/media

system/media/audio

If the user after a while of using the Reduced ROM feels that everything is working properly and does not need those files then it can be deleted but its not necessary. Removing those files can only be useful when flashing Open Gapps that require extra amount of space in the /system partition but as of now is 2.2 GB and allows for the Variant Super installation.
