- The phone worked great unpacking, but the first proposed update me completely by Samsung gun performance. I spent over a year with poor performance! Nevertheless, I could install an official update this May 2014 allowed me to find proper performance.
- The earpiece on the front broke down after 6 months. Unable to win without putting the hands-free mode or connect the handsfree-kit. Go back to a Samsung service center warranty took three weeks via AlloPSM.
- Most of the Samsung Galaxy devices (including this çi) have a backdoor that allows the brand to access your phone without your consent. A google search with the keywords "samsung backdoor" will tell you more.
- New: the battery dropped me this week (beginning in May 2014, 15 months after Échat), I have about 30 minutes of battery life by doing nothing with it, and 10 minutes of talk time. The phone will restart in service. I know bad series exist, but two service returns in 15 months it starts to do much :-(
