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:
Youtube video on how to :Unpack and Repack Android IMG/DAT files using Android Tool
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:
HP TOUCHPAD Optimize for All Android ROMs with Swap Partition

ROM_Reducer:
Moves Android system Apps from:
system/app to system/media
system/priv-app to system/media/audio


Once the Apps are Move from the system/app and system/priv-app folder they do not get install.

If the user wants to add any feature or App it can easily be done at any time using TWRP:
Mount --->> System
Advance --->> File Manager
Select system/media ( Select the App from the list )
Select Move
Select system/app ( Select Current Folder ) bottom right corner
Swipe to Confirm


Important:
system/media Apps needs to be move to system/app
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


Remove_ROM_Reducer_Apps_Backup:
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.

Click HERE for all the ROM Reducer Flash Files, Select All_Files (and the name of ROM to be use)
It is best to start with a new ROM installation for maximum stability and RAM gain.
Even if the Apps are removed some of the services could be active in the background.

How to Flash:
1. ROM
2. HpTp_Universal_Optimize_Swap
3. ROM_Reducer
4. Open Gapps

Below are the list of all the Apps and features removed from each ROM and the screenshots after install.
Using the HpTp_1782_CPU_Universal_Optimize_Swap; updated on August, 2 of 2019

Is always best to describe when the reboots occurred.
Using an App that requires high processing? The Tablet does not handle the CPU frequency selected. It will work but could reboot after the frequency has been use constantly for too long: Flash a lower frequency.

Tablet Reboots after installing or uninstalling App?
Posted on the other guide:
Older ROMs like Kitkat and Lollipop use old Kernels and never were set up to do any swapping, everything runs on the 600 MB limited Memory. The older ROMs will use the swap partition and works but after swapping and the user wants to install Apps or remove it, it will reboots. Swapping is set up to 10% on older ROMs to avoid reboots, any installation of Apps or making modification to the system must be done with a fresh start.

ROMs 7.1.2, 8.1 and 9 are the most stable to use with swap, it was setup to use zRAM and swapping was always use, older ROMs did not.

Download the appropriate "All_Files_*" zip from here and extract the ROM_Reducer from there.
