Samsung Galaxy Tab S5e Review
https://techtablets.com/samsung-ga...

This is one of the best tablet screens you’ll find, if not the best. 640 nits, bright enough to be able to use it in direct sunlight if you wanted to. The 2560 x 1600 resolution is sharp enough that eBooks and text still good. Deep blacks and a very good touch response from the touch digitizer running at 60hz the same as this screen. In the settings, you’re able to tweak the saturation and white balance. Something you cannot do on the Alldocube X Chinese tablet with the same screen. The ambient light sensor works very well, getting a pretty much perfect brightness in your environment.
