After checking all the images

You should be aware that the Pine64 folks only feature outdated and crappy OS images that show problems that are solved since ages in the meantime. They also do NOT point out that any Linux images can be upgraded the following way (as root, followed by a reboot):

Code:

bash <(curl -s https://raw.githubusercontent.com/longsleep/build-pine64-image/master/simpleimage/platform-scripts/pine64_update_uboot.sh)
bash <(curl -s https://raw.githubusercontent.com/longsleep/build-pine64-image/master/simpleimage/platform-scripts/pine64_update_kernel.sh)
bash <(curl -s https://raw.githubusercontent.com/longsleep/build-pine64-image/master/simpleimage/platform-scripts/pine64_fix_whatever.sh)

In case you don't use the real Ubuntu image (not from the Wiki but from original developer longsleep and available here) I would simply put back the SD card in your computer, format it as FAT and check it first (crashes when using Android/RemixOS might be an indication for a faulty SD card since Android uses a different partitioning scheme than Linux!). Use H2testw or f3 to check your card, if this is OK, burn longsleep's Ubuntu Xenial image the usual way. Then start it and install the Desktop environment of your choice using this script afterwards.

This way you ensure that you get an original OS image that has nearly all known issues fixed already (unlike the featured stuff in the pine64 wiki). The forums are full of reports for issues that have been fixed long ago.
