jslave written in kernel version on android phone

my previous phone and current phone have the kernel version written as this
3.10.65 +
jslave@WUH100013812#1
and
3.18.19+
jslave@WUH1000103115#1
huawei said it wasn't a kernel version but were useless, they actually had no idea and said just don't worry about it.
however after 5 years and over 20 phones,being somehow controlled,wiped,blocked,hacked,whatever you want to call it,i am doing my best to put a stop to it,please do not think i am a paroid fool,ive had phones that need factory resets to allow messages through,Vodafone constantly give me codes to unblock phone calls etc and last year I had 4 phones in a row wiped and then die on me. what I am hoping for is that in finding this jslave in my kernel that it is something that can lead to busting these ********. Does anyone have any answers for me, please?
