I just got a 6th generation Kindle paperwhite and I have to have the light up to the maximum to get a decent light to read it during the daytime indoors. Is this normal? Why would it not have a stronger light that I could dim if I wanted to? My older version of Kindle paperwhite (that I lost) had the light more in the middle to upper middle to get the strength of this one at max.
Ask for a replacement. Generally, a brightness setting of 9 is quite enough for day/night reading. Actually, 9 is still too bright in the dark.
This happens with most of the Kindles since they are mass-produced in China and don't follow the lumens standard, nor was it written anywhere in the description, so that we can verify it. I have seen the Kindle white is white but the Kindle black appears slightly yellowish to me.
