my os version is 10.2.0.1371
That would explain it. I believe that 10.2.0.1371 was one of the early 10.2 versions "leaked". If you really want the dark theme, you would have to install one of the more current versions. Be aware that leaked and beta versions are not 100%, and you must be prepared to experience a few bugs or quirks. Those bugs are ironed out before an OS is officially released through your carrier. The beta version I have installed on a second device is to help with testing the compatibility of apps with upcoming OS releases.
