EXTERNAL USB HARD DISK DRIVE
UNRECOGNIZED BY G4
G4 won’t recognize USB OTG external HDD when connected to phone
Any external Hard Disk Drive (HDD) peripherals or USB connection powered fan requiring high
power consumption will be identified as such and refused recognition as device they are by G4
phone when connected to the smartphone via USB OTG (on-the-go).
Note: If momentary power consumption by peripheral device when connected via
OTG is 600mA or greater the connection automatically gets lost.
How to fix
Standard USB rating is 500mA. Please note that in most cases peripheral devices are still being
supported if their power consumption is greater.
However, it was quickly detected an area of concerns especially when battery consumption was
found to increase rapidly and dramatically (more than four times the normal drainage) and device
often suddenly powering off due to a drained battery.
