[Android General] Viva La Android R.I.P.:
@Moxiipc that's great news that everything went smoothly. I assume you must have a fair amount of experience with Android modding, as most of the inexperienced members have difficulties on these guides to begin with. Allwinner powered devices are a bit distinct from other, more widely used chipsets in terms of modding and flashing methods. Either way, I commend your achievements on the Scepter 8.

So yes, after upgrading, unlocking.and rooting your tablet, it's certainly time to debloat unwanted apps, tweak some default parameters, and get this tablet running more smoothly. On the list of system apps you outlined, I noticed that the first five were vendor specific apps (except the Easter Egg app; it's a hidden game within the OS that you can safely uninstall). The apps with Allwinner referenced in the name are key to normal function of the tablet. Leave those alone. The Basic Daydreams app is your native interactive screensaver mode. Since it's a normal function within the OS and involves the display, leave it untouched. Almost all the rest of the apps you listed are components of the preinstalled Google Mobile Services (GMS) ecosystem. You can remove any of these you like, but keep in mind that removing core GMS components will have an impact on the Google app or service corresponding to the system app you uninstall. Experiment around with uninstalling these apps. If you inadvertently uninstall ah app that negatively affects another app or service that you use, you can always flash V9 again and fully restore your tablet to stock. The Google component apps with "overlay" in the package name are theme configurations for whichever app contains the overlay. Again, while safe to uninstall, the direct impact to related apps and services could prove unsatisfactory to your preferences.

One app you didn't list that you definitely want to uninstall is the preinstalled QLink WiFi autoconnect service that claims to connect you to thousands of free WiFi access points throughout the country. This service has an ulterior motive, however; it constantly collects "analytical data" from your device and sells that data to the highest bidder. This includes copious info about your location (it constantly tracks you) and even info about your browsing habits, interests, and personal data. Moreover, this service can turn your WiFi on automatically.at any time and against your wishes. It consumes a substantial amount of RAM and processing power, too. You will notice am immediate improvement once you uninstall it. I can't recall the package name off top, but you should know it when you see it.

When uninstalling system apps on this tablet, keep in mind that it uses the Dynamic partition scheme, meaning that your /system, /vendor and /product partitions are integrated into one /super partition. So you must use an app or file manager with dynamic partition support. I recommend using MiXplorer file manager (free of charge and ad free). It will allow you access to the logical partitions where your preinstalled apps are stored. You can go to apkmirror.com and search for MiXplorer. You will need to download the apk, install it, and go to app settings to enable root support. Preinstalled apps are in multiple directories. Here are the paths:

/system/app

/system/priv-app

/system-ext/app

/system-ext/priv-app

/product/app

/product/priv-app

For tweaking kernel parameters and build.prop values, you can follow the mods I laid out in the thread section you are referring to. Again, dynamic partitions complicate things. Use MiXplorer to manually edit the build.prop versus using an unsupported app, which will soft brick your device. I realize this is rather a lot of info. I likely won't be on XDA for a couple of days because I'm traveling for work. So if I don't reply to you in a timely manner, I haven't forgotten you. Good news is, these Allwinner devices are almost impossible to hard brick. They have a hardware embedded BROM bootloader protocol, so restoring the firmware is almost always an option if you mess up. I'll be putting a comprehensive guide together soon for modding the stock Android OS for optimal performance. I'm also actively porting LineageOS 18.1 for this tablet.

Good luck and talk to you soon.
