New moto g 3rd, android 6.0, no sd. The phone itself appears in windows, but with no drive to explore. If I put an sd in (portable or internal) it can read it ok (although this sometimes doesn't work) I've set it to MTP on the main menu (from charge only). I've also tried enabling dev settings, and setting it to MTP there as well. I've tried going into apps - system and cleared data and cache for both external and media storage (with restart). I've also tried clearing out the /cache through the funky system startup as another site suggested. No dice. If factory reset is the best option - that is an option as it's new. Gone back to first phone for now. Thanks in advance!
