Thats solid advise right there, both of my mobius cards is a 64GB one but they are also FAT32 formatted
My friend got a 8" LG tablet a few months ago, got android 6.0 on it and seem to work pretty good ( also cheap tablet )
My Asus have developed some weirdness, when using for navigation after 1 hour or so google navigation loose connection to the GPS unit though its still on, i can then turn off GPS and then back on but it still don't work, so i have to completely reboot tablet to get navigation working again.
Other apps using the GPS in the tablet work fine for hours on end, so i assume its something with the google navigation.
Myself i would never spend much on a tablet as i rarely use it, but i would like a new one as i fractured the screen on mine shortly after i got it
Still work fine but the cracks in the screen annoy the living hell out of me, and cheap or not i can afford to replace the darn thing.
Remember many reviewing tablets online review them as regular hardcore users, so maybe the battery life is not good or it get hot or cant play the newest games perfect.
But for navigation and a little file viewing and news reading while on the toilet just about any tablet will do ( off course not the dirt cheap ones made with decade old dual core processors )
PS. i also use my tablet to view the wifi feed off my CCTV system, that also work great even with the tablet and screen ( on low ) going all night with charger plugged in, it sit that way on my night stand with motion detection on so i can jump out of bed and grab my rifle ( airrifle ) in case someone vandalize my car again.
Or i can get dressed grab my steel pipe and be out of the front door and down in the street before the car or person leave the yard where its parked.
I AM THE LAW !
