previously i was using one app namely 2 flash(front and back flashlight) for the purpose of front camera flash as torch.but as i purchased a7 2018 app stopped working.showing that there is no front flash to use as torch.kindly give valuable opinion.
actually no value of power saving mode,put unused app to sleep or other power saving menu,even battery gurdian don't have any value.backup is same or better if you don't use such settings.
