To quote from the manual, "It's important to fully charge the battery before turning on you smart phone."
However, I don't see a way to tell if the phone is fully charged.
So, trying to follow the instructions, what I've done is
Called to activate the 4g service
Inserted the 4g sim card
Inserted the battery
Put the cover on
Plugged it in to charge.
At first, a battery indicator came up showing that the batter was 40% charged. But, then the screen went blank. I didn't notice if the screen said anything else. The 40% indicator was large, covering the display area.
Now it's just sitting there, totally dark. There is no light on anywhere on the phone.
I called customer support, but after looking into it (ther person admitted that they were looking at the manual for the first time), their best guess was that there was supposed to be an indicator light blinking somewhere.
I agree with that, and have little doubt that when the phone is on, there are indicator lights, but now, the first time charging it, there is no indicator light blinking. I can see several things above the Mororola logo, but they are all just dark / off.
The other comment that the support person made was that if it was 40% charged, it would probably be fully charged in about 1 hour. I'm waiting longer than that, but was wondering if anyone had any idea if there actually is an indicator.
