Basically the title.
And how important do you really think Android version updates are. I don't use my phone for a lot more than podcasts, instant messaging, and occasional browsing on Firefox mostly with JS disabled and ad-block on. I have a 3 year old Android 7 device that looks and works just fine and see no reason to upgrade
My $50 Huawei is still rocking after two years of abuse. Battery is still good but Ibelieve the NSA spyware google puts in it slows it down more than any Chinese backdoors . Just hope someone is listening to me scream into the void at this point.
