Using a Moto X 2014. I barely manage to save space to put 1 movie at most since it has just internal storage of 16gb with no expandable slot. On phone the device says I have exact 1 gb left but android file transfer says I have 500ish mb. I have tried clearing all cache and do not want to reset my phone. Cleared recycle bin using es file explorer too just to make sure. HELP :'(
