TCL has confirmed that it will provide at least one major Android OS update to both the 10 Pro and 10L. Additionally, both phones will get security updates every two months for two years.
Here's the official statement that TCL gave to Android Authority:
"We can confirm both the TCL 10 Pro and TCL 10L will, at minimum, receive one major OS update as well as SMR updates every two months for 2 years."
Both the TCL 10 Pro and 10L come with Android 10 preloaded, so today's news means that they'll be updated to Android 11. And TCL does say they'll get one Android OS update "at minimum", so it's possible that the phones could get Android 12, too.
While TCL isn't a brand new company, they are fairly new to releasing smartphones under their own name. The 10 Pro and 10L are the first phones to be sold under the TCL name in North America. Because of that, this might be the first time that some consumers are hearing of TCL, and so guaranteeing at least one major OS update and two years of security updates can help those people feel more confident about buying a TCL phone.
