My charger cover broke 2 weeks to the day after purchasing the Galaxy S5. I was on the phone with AT&T and Samsung for roughly 3 hours total, no exaggeration. Samsung told me this was not a known issue and that I would have to pay and go through the process of mailing phones back and forth while the cover was fixed. I was very frustrated talking to these two companies. Samsung especially, who pride themselves in customer service. Their response of "It's not a known issue" is absurd. How long has the phone been out? Issues have to start somewhere.
Since I've checked this forum, there have been many, many more people having the same problem. This piece, which costs less than say $5, the companies are making their consumers jump through hoops for a devices that are less than a month old to get fixed. Sounds like it should be a known issue to Samsung by now and they should be doing something about it.
My end result, I called AT&T as a final last breath of hope and getting my point across and I was able to get a new phone. I convinced them that I had a defective phone and the piece broke off, it was NOT physical damage and to have a nice brand new phone break like this was crazy. Key words! My persistence paid off, but there was a lot of frustration and hours wasted on my weekend morning dealing with this. Was not fun. The S5 charger cover will continue to be an issue. I bet the new one will break soon enough. Good luck everyone.
In addition - I am grateful AT&T helped out with this and shows a new light on Samsung's customer service for a brand new device which has high competition. Samsung should have been the one to solve this issue, not the phone carrier.
