I have been fighting with Tripltek for the last 3 weeks on why my tablet is very glichy and freezes with using the DJI Fly app. They said the problem was my cable, even if I have been using the cable for the last year. I purchased three more cables and used with the adapter that came with my tablet and still the same awful results. Last week I downloaded Litchi Beta and now everything is smooth and works as it should. I even used my old cable and the three new cables i purchased with no issues. When I reported back to Tripltek with my results, they sent back another canned email saying there is no problem with the Fly app and the problem is my cable! I love the brightness of the Tripltek but the tech support is clueless and offers no help.
