I bought a samsung galaxy tab s 10.5 Amole color for cash at Walmart it is running android 6 I think does not take a sim card but does use a expanded memory card is there any way to upgrade to a better android version I love samsung galaxy line of products and also looking how to contact samsung to be a possible tester and reviewer for new products thank for all the wonderful products so far

Only possible way to get a more recent version of Android, would depend on a few things:

• Being able to Root the device. 
• Finding a Custom Rom on XDA, if one exists? 
• Flashing the Custom Rom.

How can I do this

You can start with this, it's for the Galaxy Tab 10.5, but I'm not sure if it's for the same chipset as your device.
