for those who's astogo 8.0.4.2 stopped working recently, and those who haven't got it but want to:
astrogo 8.0.4.2 was the only version that worked on my ue630x for a long time; other/later versions do not work.

today (or yesterday), 8.0.4.2 also stopped working, likely got phased out by astro support.

thanks to a tip from a fellow forumer/tv owner, i was able to install the latest 8.1.98 and got it to work.

app is not in playstore; also can't get it to work using normal sideload.
what i did:

install a browser (i use brave), but think chrome or other browser will work too.

search for astrogo apk, find in apkpure or other.

download, open, log in, all good.

i hope that works for u!

Install adaptive rotation lock app, from playstore.

And indic keyboard, of course, also from playstore.

These 2 are prerequisites to using astrogo.

still no good?

i just realized that this rotation lock app may not be in tv playstore.

this is the one i am using, just sideload:
