Well, I also tried a scan folder back up to a USB thumb drive after updating my System version and Lib Com on my new Maxi Sys Elite. My system with current V3.65 will not allow ES Explorer to write to external storage (USB thumb drive) to make a Scan Folder backup, even though you get messages for updates strongly urging you to create to backup my software.
It wasn't a complete waste of time though, the process of trying to figure out if I have enough storage space or not to fit 42 updates, and where the micro SD slot is actually hidden at , I was pleasantly surprised to find the battery listing 15400 mah vs 13600mah and internal memory size over 53gb versus spec of 32gb listed for MaxiSys Elite . Maybe a Beta unit? SSSShhhh Quiet ! This might be a BETA unit of a coming Elite S? Unannounced Improvements to MaxiSYS Elite? . Remote desk worked. (Team Viewer V14.3) Thumbs Up.
Don't like that The power button on this doesn't glow like my MS908P when pressed to acknowledge powering up so I pressed it a second time and the touch screen acted goofy a few seconds rolling from one side to another. I shut it off and powered it up again and screen seemed fine, but hoping the screen isn't going to become a future issue. I once in a while notice slight changes to intensity of back lighting but these supposed to automatically adjust to changing lighting conditions and to your finger like a 70's mood ring , so if you're a Bi Polar Lunatic you'll probably have to send it in for repairs, LOL.
