[Galaxy Tab S Q&A, Help & Troubleshooting] Canadoc:
, well I have now owned and returned a few different Galaxy Tab s 10.5 models. The first one was an open box model which clearly had a stark difference that was uneven in the whites with half the screen being more greenish and half being reddish and that was returned immediately. After that I decided to try my luck with the smaller tab f 8.4 model which I did not like that much. I found the battery life too short and I found it a bit awkward to hold the side bezels were so narrow.

So I managed to get on sale a new tab s 10.5 it seem to be a newer batch as the serial number seems significantly newer. The uniformity of the screen is much better however what I did notice was that even in, adapt display mode the screen had a slight brownish hue to the whites. This was not the case on one of the previous models I returned that had very good white but had a artefactual banding pattern to the screen.

While I am still within the 14 day return. The tab went on sale at another store for a good price, & I elected to buy one from there hoping to have slightly better luck. This unit seems to be an older serial number from the looks of it. However the uniformity is also quite good and where the previous model I am contemplating keeping has a slight brownish tint the 10th here on white a little more towards the yellow.

But overall especially at brighter settings seemed slightly more white to the naked eye although this was only really evident when comparing the two side by side at similar brightness levels.

So now after my long winded description, here is my observation and dilemma. I have installed a CPU temp app that shows the temperature in the notification bar. The reason for doing this was I felt that the newest tab with the slightly more yellow tint at times I felt a little bit warm near the camera. This is what I observed:

Most of the time the yellow tinted tab actually had over all the same to slightly cooler temperatures by 1 to 2 degrees Celsius when in most applications or the normal background or watching a video. However when using Google Chrome with all settings identical between the two tablets, the tablet with the slightly brown or 10th seemed the majority of the time to run as much as 10 degrees Celsius cooler. With most of the time is running between 35 and 40 degrees Celsius and the yellowish tinted tab running between 42 and 48 degrees Celsius. Oddly if I disable JavaScript from Google Chrome the and reloaded it the web sites would then show a similar temperature. I reloaded and tested this multiple times and kept getting consistent results.

So the question finally remains as to which tablet I should keep, the one where the whites are a faint bit whiter with a slight yellowish tint the most of the time runs minimally cooler but when browsing with chrome can run as much as 10 degrees warmer and can sometimes feel noticeably warmer to the touch near the camera area or do I go for the one who screen is marginally brown or intent but has the newer serial number and seems to feel cooler to the touch.

Also can anyone explain why I would see that effect with JavaScript between the same web page on two sites even with multiple reloads? It was consistently favoring the temperature by as much as 10 degrees one tablet to the other. Also have any of you noticed a similar effect with your tablet?
