Welcome, good sir, and glad to have you back in the world... <smile>
I got tired of Boost's nonsense (being forced to upgrade to a 5g phone, allegedly free, but actually about 250 bucks in all), and went to T-Mobile. Since they were cheap and I needed 3 of them, and, with all the upgrades to 5g, likely needed to offload a few traincars of them, we got 3 TMRVL4G devices...
Since it's Wingtech, which really isn't one of the biggies, but, as I've been on this venue all these years, through many devices, I'm always willing to be a guinea pig... My coding chops are decades old, and really revolve around Delphi, CodeTyphon, and old XBase stuff... Never learned C++ nor really much .java, so coding for Android is, while interesting to me, and I can generally read and follow others' work, just the syntax and symbology are difficult for me. (What can I say? Turned 65 this past Valentine's Day, and it shows at the damnedest times... <grin>)
But, should you happen across any recent information regarding any work on rooting this device, or, at the least, enabling the app-to-SD functionality which is available for every other device I've ever owned, I'd be most grateful. Add to that, I've got plenty of legit Play Store-approved apps for which I've paid real money, but can't use as they each require root access... It's not that I disapprove the companies' making admin access difficult (hey, I've boneheaded enough over the years, but give me a way to get back to default and I'm good... I also have a modest collection of paperweights where, "Sorry, dude... you're hosed..." LOL)...
It's that they each try to out-do each other in how impossible they can make it for even experienced users, but without access to their tech-support frame, to actually use these things as they're capable... I mean, ****... a quad-core device, fast as hell, and storage out the wazoo for most users. Not me, mind you, as, were some functionality enabled, this beastie would be a quick laptop replacement, with the Bluetooth keyboard which also seems to not talk to it.
Again, good sir, welcome, and welcome back!
