Sorry for the delay of valuation, I've been testing the device. Overall quality of the G4 is good for a 2 hand phone, standby time close to 3 days without stopping and little use, although the battery discharges more when using it as a wifi hotspot with a laptop or when taking many photos. Full battery charge in just over 3 hours with a 1 Amp charger. Viewing the screen is very good in all light conditions, especially outdoors and the use of GPS with Gugel-Maps is accurate. Sound quality on calls is good, although at first I heard a "throat clearing" but it has corrected itself, and it works great with the Bluetooth in the car. I would trust you again when buying a "new" technological device, and I will recommend you to my friends if they need anything. I am happy with my purchase. Thank you very much for offering reliable items and giving them another life by putting them to work, rather than retiring them. Best regards, Carlos.

6 months later the battery is no longer able to hold a charge or even charge at all despite the purchase of a charger
