  1. Not an issue with service provider! This phone is a POS. Loaded with unwanted and unnecessary Samsung and Google bloatware. Over half of the phone’s usable memory is taken by this ridiculous amount of undesirable company offal!!!
    I’m poor but I’m not stupid. I know what a scam is and this is it.
    No-one can simply buy a working device without these mega corps having their fingers in your device and your business.
    I will scrape together enough money to buy a device without all this useless crap and without the hindrance of undesirable corporate intrusions.
