Here are my issues with the S3, which I've owned for about a month and a half:
- Group Messaging. My friends use iMessage a lot, and there is little-to-no support for group text messaging. I have tried numerous third-party apps without luck (I hear Verizon Messenger is pretty good, but I have Sprint..), and constantly miss texts or receive group responses as individual messages.
- Silenced mode w/ headphone support. I use my headphones nearly all day. I listen to radio, podcasts, etc, and cannot keep my phone on "silent" if I want any volume through my headphones. If I receive any alerts (text/call) while listening, the actual device makes an external noise, too. I can silence alerts, but it would be more convenient to alert me via the headphones, and not the actual phone speaker.
- Poor WiFi signal. I have received absolutely TERRIBLE WiFi signal with this phone, despite having reset to factory defaults, and it's easily replicated with other devices right next to it. I know Apple artificially "boosts" the signal icon, but this is sporadic reception altogether, and I often lose signal when moving a matter of feet in any direction.
- Apps. I am VERY happy with the breadth and scope of Apps for the phone, especially those that allow you to tweak the way your phone acts (GUI), looks (alert colors), and sounds... but these apps often lacking. Certain apps simply aren't compatible with the S3, while others miss features that appear on the iPhone versions (my favorite app, TuneIn, is a radio app that has NO PAUSE FEATURE on the Android version).
The screen size is very nice, even if my palm does sometimes hit the "back" button while reaching for either the volume or power buttons; this is more an issue of me getting used to it, than it is a structural fault, despite Apple's advertising claims. The battery life is GREAT, as well.
