Before I start: my phone is being replaced because the WiFi connection is completely broken, but I want to make sure this problem is not recurring when I get my new phone (the whole 14 day return thing, etc). My phone intermittently does not come out of sleep when getting a call or text. I have rebooted, hard reset, erased, and restored the phone. My email is turned to manual. The switch is set to ring and volume turned up all the way. When I say it doesn't come out, it doesn't light up, vibrate, or make a noise until I click on it to bring it out of sleep. Then it tells me I have a missed call, voicemail, and text. I can't keep this phone if I miss every single call and text, it defeats the purpose of having it. I only have one phone, so getting calls can be pretty important. I have perfectly fine network coverage. It's not always full bar, but it is ALWAYS enough to text, email, or call. If the phone is already unlocked, like if I am looking at my calendar, then the call/text/etc will come through audible with vibrate in addition. In addition, the phone is sooooo quiet. I can't feel it vibrate in my holster because the text message vibration lasts like a tenth of a second, and it's really not loud at all. Potentially, I have three defects with this phone: WiFi broken, bad speaker/low sound, won't come out of unlock. Is it really THAT likely to have all three defects in ONE brand new phone? I hope these incidents don't repeat when I get my new phone. Any thoughts are appreciated.
