I've used phones with half the number of cores and half that RAM and it was fine.
As to the tablet I have a few outdated Fire 8's but thanks to the Internet I sideloaded the Google app store and it seems fine as a generic Android tablet.
If you must have a real Android tablet I'd consider the Samsung models next.
PS. Edited for typo.
New fire hd 10 is coming end of the month.
I have the 2017 model I got bkack friday day after thanksgiving 2017 for 99 dollars. Mine is 32gb. Its the same dimensions and same 10 inch screen. And the back camera is the same 2mp. Except front is 2mp now also.
But the old one is 2gb ram. I dont play games but some basic ones like unblock work great. But if the new one doesnt I will live. I am ot a heavy gamer.
But besides its plenty. Netflix works great. And light web and ensil not much heavy apps. Even xfinity stream works awesome I have comcast. I can stream all my showsor dvr pretty smooth.
But the 2017 is old os and outdated now. My chase bank app requires nouget 7 now. And the my fire has 5 based lolipo s no good. From web silk or firefox or chrome it works but still wouldrather use the app.
Everything works great. But lolipop is outdated. Even nougat is outdated. My motorola z3 play is 4gb ram and octacore. And pie 9 based.
Also the new fire is octacore so big upgrade. But still only 2gb ram. 2 is not enough is it? It is cheap I get it. But still just making it 3 or 4gb would not of been too expensive? I mean if 2017 is 2gb the new shouldbe at least 3 or 4. I don care for the camera because my motorola z3 playis pretty good. But2gb does not cut it in my opinion. My cellphone is 4gand is awesome. My old motorola G4 play was 2 gb and slow. Butit was also octa core vs quad so maybe thst is it.
And the new fire is USB C. Big help. Micro is so flimsy. Show mode dock helps but still C is much getter.
So I am all set to buy one. But the question is the ram. Having octa core will speed it up. But 2gb migh not help. Or octa is good enough and 2gb ram does not matter? Even netflix and email and light web.
Or maybe ebay the old 2017 and get the new on soit not too bad price wise. But what can I get for it? 50 at least?
