Oh... Sadly this one is not a Tier 1 manufacturer and doesnt just publish the latest version. I saw online that it was version 12 out of the box so if you truly have the 11 one, you might have been scammed. I would recommend not going with honor in the future ( thats my personal opinion, you might like the device ). Look if there are custom ROMs for it that might have a newer version
I would strongly reccomend google pixels and oneplus. In my expirience they have been the best i could ask for, had a Oneplus 6 and now a pixel 6 and i am very happy, they might have a "premium" price tag but i consider them an investment since i use them every day ( even for work, i do development ) and typically last a while ( my OP6 lasted 5 years and i needed to switch to the Pixel 6 for the new android versions due to programming ).
