[Solved] Best Smart TV Box under PLN 300: Xiaomi Mi, A5X Max, H96 Max for Samsung UE40D6500 & New TV

I intend to buy a smart tv box up to PLN 300 to "tune" my old Samsung TV UE40D6500, but later it will be used for a new tv, which I intend to buy -> https://www.elektroda.pl/rtvforum/viewtopic. php? p = 17482564 # 17482564 giving up the opportunity in cable TV
It is important that KODI, Netflix, HBO Go, Showmax, NC + go, player.pl, Ipla, cda.pl etc. work on it.
Currently I have searched for such, but I do not know if they meet the requirements:
Xiaomi Mi BOX TV Android 6.0 2 / 8GB - can it be upgraded to 8.1?
A5X Max TV BOX Android 8.1 OREO 4 / 32GB
H96 Max H2 TV BOX ANDROID 7.1 4GB / 32GB

In fact, RPi / Orange PI with Kodi installed is enough.
You have a lot of additions to Kodi and no additional applications are needed.

... and from those I mentioned?

Check manufacturers' websites for updates, read descriptions on the web, view YT reviews so you'll know something more about the capabilities of the devices.
Now in the chain of shops with an insect in the name is Hykker - there are tests on YT - it is not the worst.

ok, is it possible to upload apps from external sources on these models?

This Hykker has 1GB of RAM and 8GB of memory, and it's probably too few apps to install

Hello colleagues
I have a question whether the SD card with KODI and other installed programs prepared and working properly under Rasberry Pi 3 B + after inserting the tv box a5x max + to the SD slot will start the tv box and start with the KODI installed on it - do you need to carry out any additional modifications?

I have a box with such parameters - what would you suggest to upload, where to find it and how to upload it?
Will it not be problematic or complicated uploading? Will the other menu from the Box stay?
