TCL backs its new 50 series of Android smartphones to deliver the OEM's greatest depth of choice and features yet. It goes from the super-affordable LE variant to the more premium XL and XE 5G, both of which are slated to debut with and without the OEM's eye-comfort-enhancing NXTPAPER technology. Most of the line will be available in the US, whereas others are headed to the EMEA region.
