I like to shoot a stop or to underexposed ... the problem is it is hard to see what's happening on the screen when the colors are not so bright. I have tried increasing my screen brightness to maximum however I'm wondering if there are any other tricks. Thank you for any suggestions.

you may have to wear FPV goggles, or get in under the shade, or a shade over the tablet.
The only other option is shoot normally and fix it in post to your taste........you sound like a good candidate for RAW Shooting

Raw is where it's at.
I never shoot jpegs. Too dirty looking, dark and loss of detail and definition.
Soooooo much can be done in post with raw / dng.

Not all tablets are created equal.  I have better luck seeing the screen on my IOS devices than on my Android stuff.  Actually my iPhone 6 is even better than my iPad Air 2.  But that means I have to wear my cheater glasses for my 64 year old eyes to be able to read the DJI Go labels  
Standing in the shade also helps, even if you use a shield.

Thanks for those suggestions. I shoot the raw bracketed still shots. Time to go fpv I guess. Thanks again

I hate shooting raw..... I don't edit my pics I just make sure Im taking clean pics at the time lol

Its not always possible , and its almost always the case you will get better results shooting RAW........I like to record every single pixel the sensor is capable of capturing.........I don't trust the camera to decide what pixels to delete....they may be the wrong ones, and they always are the wrong ones in the High and low area's of the image.
for stuff that doesn't matter though like holiday snaps its ok I guess.
