Remove password from Galaxy Tab4 My wife set password to her tablet and asks me to remove it. I opened settings -&gt; security -&gt; device encryption entering password but option none (i.e. no password) is disabled (with message turned off by administrator, policy...). As I understand if I am able to set password to none then password should disappears. But I cannot do it, so I suspecting that she is encrypted device somehow.

Is there way to ensure that device encrypted or not? If it is encrypted there is only one way, as I know, hard reset it to remove encryption. But if it is not encrypted, how to remove password?
