My thoughts on the why the low-res image looks wonky...
1) you're using a tiny camera sensor from your tablet.
2) It set to auto ISO, so it's probably bumping up the ISO to 1600ish, so you're getting a noisy capture.
3) Because of the higher ISO on a smaller sensor, the tablet software is likely applying a built-in noise reduction.
4) You're posting the image a large size - even though screen resolution is roughly 75ppi.
Combine all those elements, and you're getting a very mottled image.
The larger the sensor and the larger the photo sites (like 12MP), the better overall image quality at higher ISOs. The Sony a7sII has 12 MP, and is (so far) the king of high ISO.
However, there is a most full-frame 35mm and APS-C sensors are damn good up to ISO 1600. Better than anything I used when I first started 10 years ago. Plus, you can get REALLY good used cameras for dirt cheap.
Even the new Fuji mirrorless cameras (APS-C sized sensor) is outstanding.
The Olympus Mirrorless Micro 4:3 cameras are ridiculously good. The new Olympus Pen-F is crazy good. I think that may be my next camera.

This Olympus Pen-F

...
http://www.bhphotovideo.com/c/product/9 ... _lens.htmlAnd you have wonderful small kit that can do SO much.
For Fuji...
There is this generation older camera...
http://www.bhphotovideo.com/c/product/1 ... amera.htmlwith this 50mm equivalent lens...
http://www.bhphotovideo.com/c/product/1 ... f_2_r.htmlAnd you'd also have a nice simple kit that can do a LOT. ...though shooting in smaller rooms indoors, you're limited because of the 50mm field of view.
I feel like I should put together a recommended camera post.
