LG V20 phone, Verizon carrier - I used the content lock on some pics in my photo gallery. When I download them to my pc I can't open them. How do I open them on my PC? Also, is there a way to remove the content lock from a file on my android phone? I accidently locked one I didn't mean to lock. If I change the content lock code in the security settings, will that change it for all locked files, or just the ones I lock after the change? Why doesn't android have an option to cancel the content lock code?
