I have never liked the Galaxy phones, not to say they are not a nice phone.
Keep in mind that the S5 has the same TriBand Qualcomm Chip and Radio as the M8 and probably very similar firmware as well.
I suspect a "Working" M8 will run very similar to an S5.
Granted some M8's are not working correctly.
It's also extremely painful to get an M8 swapped out if you are over 14 days.
I had an S5 in my hands and brought home but stupid BestBuy sales clerk sold me a Verizon. In that time span I decided I prefer stay with the Devil I Know and got another M8.
If you are under 14days and you are having Network issues on an M8. SWAP IT OUT IMMEDIATELY.
New M8 is night and day working better. But I am very worried long term how it will hold up.
