LG a décidé de jouer la carte de la sécurité avec Son prochain smartphone haut de gamme G6. We offer a variety of cellular antennas you can attach that will work on buildings or vehicles. We have an external antenna adapter (see products below) that connects to this port and an antenna. The AC791L has small antenna ports located on the bottom (covered by plugs).This time, try holding down the power button for at least 5 seconds. In order to check if the issue is with the battery, plug in the charger for at least 15 minutes and try to power on the device again. The device may not be turning on because the battery is dead or almost dead.
