Any discussion on using LapTimer. Please use this forum in case you need guidance on how to use LapTimer or perform a certain operation
Oh also when I tested the app before adding the ODB II and external GPS video seemed to work. I will do some more testing and let you know.
The statement on the 300 US$ is probably not a fair one No frankly, the Samsung Tab 4 works with LapTimer in general. The problem can be in many areas, in hardware variances, it is probably some special configuration for your device, some other apps etc. You never know. Without holding the device in my hands it is impossible to find exactly what is wrong with it. Due to the number of different devices and OS versions, that's a difficult topic in Android. In case you do not want to use LapTimer in the future, please check the Extended Refund Policy, it is exactly for cases like this.
