In the process of checking the settings on my Sony Xperia XA I came across the Linux Kernel information. Version 3.18.35 was released in June 2016 but the date shown is from 2017:
3.18.35+ BuildUser@BuildHost #1 Fri Sep 15 05:31 CST 2017
Is it normal for the date shown here to be later than the release date? I assume it may represent the last automatic update. Also, what does the + sign mean next to the version number?.
I have no idea what BuildUser@BuildHost is but I am hoping someone can reassure me that it is normal for Sony phones :-)
