Instead of GApps and if you don't need Google baggage, why not try MicroG? Install all pieces of them. Use Lucky Patcher to patch kernel to spoof signature (after installing su manager of course). MicroG settings will show up all checked! You can use F-Droid, ApkPure, Aptoide etc. to download apps. I also use KillApps to kill everything except MicroG stuff, su, AFWall+ on startup and get about 800MB free on 19.1.

Ill have to investigate what microg is. I use aurora store but it wont let me play the games I download it for. I have most of the apps I use in .apk form so the store isn't necessary. Just use a dedicated device for that. where do you get killapps?
Well, it's only got 2GB of RAM, and with 19.0 it's averaging less than 500MB free; anything moderately intensive overloads it, so it spends a lot of time swapping back and forth between working memory and flash, which takes up processor time.

Has anyone been able to get GApps working on 18.1?
running 18 it says i have little over 600 free no gapps. Kill everything apps may help, but gapps really seems to put a performance hit on it which is why I settled wihout for now.

So it sounds like the only thing that would really benefit this severely neutered device would be an extremely lightweight build - perhaps something close to barebones AOSP with minimal Gapps. If we can keep system CPU and memory usage to a minimum while still retaining a basic platform for Google services, it would probably work OK for causal use - web browsing, Kindle, social media, etc. Forget doing anything moderately intensive.

But that's what you get for a budget tablet.

You can get killapps from Apkpure, aptoide etc.

https://killapps.en.aptoide.com/app
Contrary to V0latyle, the GSI rom perform very well, no crashes so far. The reason why using MicroG, AFwall+ or Bromite System Webview (enable in Developer mode after install) is privacy!

The only issue is AppManager (to disable trackers) doesn't work so far because its API to su (rather old) interface is broken.

Thank you, I've been needing other sources for apps. I just realized you said you got 800mb free on 19.1, hows that running? Do you have a tap delay when coming out of sleep or after the device has set for 10 seconds or so? It'll register my taps but takes a second and I've been trying to figure out how to make it a little more responsive. I also want to get into asop building or really like the idea of porting linux to this device. The fact lineageos runs on it gives me hope of a somewhat easy port.

I have customized this ROM beyond recognition. I replaced the default font with ovo font, changed the boot animations, changed the launcher from default trebuchet, removed those extraneous locale fonts from /system/fonts to free up some space for adaway /system/etc/hosts file...and so on. No lags. The only other issue is when shutdown and left plugged in, the "Samsung Galaxy Tab A" logo lit up forever...

Is it able to flash it on SM-T295, too?
Its a GSM image i believe so you should be able to flash it to most anything newer. Ive had success(somewhat) flashing these images on other devices. I believe when I looked it up before the sm-t295 is just a different version of the t290 so it should work. If you try it then let us know because this was already asked. Keep in mind that no one is responsible for what you do to your stuff.

Where exactly is the TWRP file? I'm going to install it on my table, but I couldn't find it. Can you link to it?

Should be it. Look for "sm-t290" when your trying to search, it should provide better results.

Also, to anyone just reading this thread, andy yan has updated since the original posts so make sure you grab the updated versions.

Nice. I installed a los phh A11 gsi but not much a fan of read only system and phh. Its definitely an improvement!!!! I'm going to try a Dot OS gsi next. I forgot to backup my stock boot.img lol so don't forget to. No biggie I'll just reflash stock but I may remove stock recovery from AP tar first :)
Let us know how dot os runs, i might try it tonight. Id like to make my own custom asop but aint gonna try it on only 8 gigs of ram. Im runnin los 19 but it really doesnt do good with anything but running termux and gapps just makes it useless.

Hi everyone, I was just given this tablet by a friend. It’s running android 11 and I was wondering if there were any better roms. I’m really just going to try and use it for N64 emulators. Mainly Zelda OOT

Dunno if you got any help with this but I suggest reading this tread. I settled on the latest lineage os 19 build without gapps. I use aururo store (how ever its spelled) to download stuff from the playstore. I use termux, vmware horizon, and accasionaly play baulders gate on it. It wont play newer games though. Ie: i know diablo wont run on it.

    Build in the works. Going to release the BETA as soon as I can do testing on my own device before release.

    IMO this is a necessity as there are literally no good roms for this right now. I tried the port of the Nexus stock CR rom and it was not great. Playstore was unusable due to an issue were the app thinks the system is out of storage space, even though it is almost empty. Chrome crashes instantly, the search on the page home screen flickers up/down without control.

    I am a far bigger fan of LineageOS thus why I am working on this build.

    More to come.

    Thank you my guy I had lost all hope for custom roms on this tablet. It's quite relieving to know that I'm not alone.
    Hey Guys,

    I didnt end up building a custom rom, because I was able to get the GSI version of Lineage 19 working fairly easily. Just use the correct image and flash the same as the Nexus post. Android 12 with Lineage 19 so i felt it wasnt worth it as everything works. I had trouble at first with a boot loop but that was because I had installed Magisk BEFORE the GSI rom and not AFTER. So dont make my mistake.

    As per the Nexus Post;
    Unlock Bootloader
    flash TWRP
    Wipe data
    Install Andy Yan's Lineage OS 19 GSI
    Install Magisk
    Reboot

    Cheers!

    As a follow up to my original post I wanted to mention that for anyone who wants a new ROM on their SM-T290 until this is finished development, use the Nexus Rom by Magendanz. I was able to do a fresh stock firmware install and retry the rom and my opinion has changed. I have noticed that these Tab A 8.0 tablets have been used a lot for like Uber/Door Dash and other POS terminals. I am pretty sure a lot of them have modified or customized firmware for these reasons and when I mine second hand it was from a pizza store. I think that messed up the upgrade.

    Overall Magendanz did a great job, when you install it properly. I have zero issues with functionality now, TWRP recovery set up, as well as Magisk installed and everything is running extremely well.

    As far as instruction on how to install. Take a look at some of the comments further down on the Nexus thread. That is what I did this time around and it worked perfectly. Last thing I did was copy Magisk.Apk to my SD, change extension from .APK to .ZIP, then boot into TWRP and install that ZIP.

    Going to update progression on a monthly basis as far as the LineageOS 18.0 build
