It's disappointing how much junk gets shipped in non-Google ROMs and how little OEMs seem to care. I bought a Xiaomi phone several years ago and in addition to the usual bloatware it came complete with Qualcomm radio debugging tools running in the background, including a copy of tcpdump running on all interfaces constantly logging to the internal storage. I rooted and removed it, but after Google Pay and various other apps stopped working I decided to upgrade to the latest model last year. I was sure that in the three years since my old phone that someone at Xiaomi would have noticed battery-sapping debug tools running in the background of their ROM. Of course the new phone has the exact same problem.
