Hi guys, Inwas having the same problem for few weeks. I’ve tried every app version shared here, without any luck. My dvr was working, did some adas jobs but, as you mentioned before, no gps stamp. Today I did a factory reset (I know, it’s not very convenient) and reinstalled app feom dvr internal memory than updated to 1.001135. Now my dvr shows connected in dudu adas widget and I can enjoy full functionality. Mts mention also that dvr is at fw version 0.0.23. Hope this helps
