Yeah I'm getting pretty irritated at samsung for not updating the operating system to android 10 on this a10e. I just bought mine a month ago at cricket wireless and the guy there is saying it should be updated already. What the heck is going on here Samsung.
I don't know why the A10 was not listed but I do believe that the A10e will get it. This source says that it has already came out today.
However, I do not know about the sources reliability. I have heard that the Android 10 update will come with the June monthly security update. My service provider gives me these updates exactly 1 month late so I expect to get mines in July.
