I have several versions of igo Nextgen 64-bit that work on other tablets, like Samsung, but they won't work on a Lenovo TB311FU tablet. The program crashes after launching. There's no error message. I've tried the igo PAL, igo WORLD, and igo ISRAEL versions. I've enabled all program permissions. I've read that the problem might be with the internal memory, as it's shared with RAM. Thanks for advice.
