Their service support has not improved.

Had swollen battery replaced in a Galaxy S6 twice. The second time I had to pay $200 to have it looked at. Was advised a battery replacement (even if not faulty) should be no more than $110. After 7 weeks, 12 (or 13) phone calls and over 15 hours on the phone, I was told I'll be contacted withing 24-48 hours each time... Not even 1 call back. I requested email notification.. never happened. Even a person handling my case promised to email me that same day... 4 days at time of this writing and still waiting.
Have bought many Samsung goods in the past and bought the S6 as I wanted to avoid being an iPhone sheep.
Never again will I buy a Samsung product. Their penny pinching repair philosophy over $200 will cost them thousands of $ in future sales from me, my family and all my friends that I will talk to.
