After successfully using Litchi for weeks on my android phone, suddenly I discovered that the app no longer works. Clicking on the icon results in a totally black screen presenting itself, then the screen disappears and the opening app screen of the phone appears. The same thing occurs after 4 re-installs of Litchi. The phone has over 1 GB of free storage space. The DJI-Go app works fine. BUT I un-installed DJI-Go and still Litchi won't load. The only app I installed recently was Uber. Thinking it might have caused a problem with LITCHI, I un-installed it. Same problem persisted. Should I reset the phone's Android system??
