Just looking for "Galaxy S3 Sudden Death", "Galaxy S3 Freezes", "Galaxy S3 cracks", "Galaxy S3 reception" or "Galaxy S3 invites not" looking for - you will find reading for months.
My Experiences:
A few months ago I bought a Galaxy S3 and was also a long time satisfied. Then suddenly, the Galaxy S3 could no longer load and the data connection via USB to the computer is no longer possible or constantly breaks off. One battery charge is now tested with various original Samsung chargers and USB cables partially not, in some cases only very slow or breaks possible after an extremely slow charge after several hours from complete, without further charging.
"Galaxy S3 no longer invites"
Can happen, I thought, it will be a Monday device that's why I am in good spirits turned to the Samsung support. I was the address communicated to a support workshop to which I should send my smartphone. I did that and got my phone back the way I had submitted it, incl. The defect and thus completely unrepaired. And after a waiting period of 1 1/2 weeks.
There followed a complaint from my side that has not been taken absolutely seriously unconcerned by the support and was answered with the release of another service workshop. A fresh complaint under detailed description of the defect resulted in another totally noncommittal statements this error is not known. As then, however, evidence was that such errors so often caused by a fall or water damage, it all came to me more before than funny.
A search on the Internet (search for. B .: Galaxy S3 and Galaxy S3 battery is not charging battery not charging) promoted many thousands of users in forums and reports on evaluation platforms revealed. Interestingly, a lot of experience in the reports cover: Returns from the service without repair workshops, references to alleged water damage or falls, totally inadequate handling of guarantee, etc.
The error can not be unaware of Samsung and just in these circumstances it is a joke, as the warranty processing is handled. I am absolutely shocked at how Samsung treats its customers and will not accept this behavior and proceed with all the possibilities, however. I've got my Galaxy S3 now submitted again and will update this report.
I recommend to all Galaxy S3 owners with similar problems, not to be of Samsung-around by the nose, to complain and to post the experience on the Internet. The charging problems seem a very widespread defect of S3 to be and there are many useful reports to next to many other frequently occurring hardware defects. It is totally unacceptable that a manufacturer runs here from the affair.
Update 01/12/2012: My phone is now again for a week in the service workshop (this time ECC ESC). There nobody feels responsible ("We can not give any information, we currently have so much to do, perhaps, the next week what") and Samsung also are still no information and you do not feel responsible. One finds it normal that I now since almost 4 weeks can not use my phone and complaints are Samsung could not care less.
Update 03.12.2012: Further, no information in the service workshop or Samsung. My S3 is now evident around somewhere, and the output is open. Anyone who buys a Samsung device and at some point may have problems, look forward to this service.
Update 04.12.2012: Well actually confirmation that my smartphone is in the service workshop for 8 days and not so far been processed. It is expected this week something ...
Update 05.12.2012: Since 12 days my Galaxy S3 is the second time due to the current defects go. Overall, I can not my device now for 4 1/2 weeks not allowed. Since then at least 9 days, it is the current Reaparaturwerkstatt without something is done. According to a statement from Samsung we currently have capacity problems, because there is currently a large number of submissions give (because probably why?). This is totally unacceptable. Had I known how frequently occurring defects in the new smartphones from Samsung and Samsung as bypasses in these cases with their own customers, would be alone that a reason for me was not to buy Samsung device. For the future, I have drawn my own conclusions.
Update 05.01.2013: Finally, my Galaxy S3 has been supplied by ECC ESC - after only times two weeks, did not do anything. Overall, I therefore have to wait because of the extremely poor service processing from Samsung for 5 weeks, that my smartphone is working again - totally unacceptable. It was not a repair report here, but this time was obviously done something, because now it loads again. It was obviously a hardware defect and I advise all concerned not to be fobbed off by Samsung. It can not be that the user has to wrangle with chargers and cables. This is obviously an often occurring defect.
My conclusion: Samsung I will turn their backs in the future. The devices may be interesting in itself and good - but if you have to resort to such an ignorant and obviously planned with full conviction service that can only speak against Samsung. Another conclusion is not me, I myself very involved in the five weeks that an effective repair can take place. My efforts were ignored and the employees of the service department only mastered the stalling and using obvious platitudes ("... the satisfaction of our customers is very important to us ..."), nothing more. In addition, technical problems with S3 seem to be not uncommon, and the warranty claim must therefore be thoroughly planned.
