我的男朋友在开玩笑,将我的私人照片设置为壁纸。

我删除了照片,但壁纸仍然存在...

浏览网上的某些信息后,我发现壁纸保存到over over rooting后才能访问。

如果我更改壁纸,之前的壁纸会自动删除吗?

如果不是,因为它在一个文件夹中保存,因为它只能在rooting后访问,因为它是安全的?或者它仍然有可能被其他人攻击?

english

My boyfriend was kidding with me, setting my private photo as wallpaper.

I deleted the photo but the wallpaper still remains there...

After browsing through some information on the net, I found out that the wallpaper is saved to a folder which only can be accessed after rooting.

If I change the wallpaper, will the previous wallpaper automatically be deleted?

If not, since it is saving in a folder which only can be accessed after rooting, is it safe? Or does it still have a possibility of being hacked by others?

最佳答案
 

作为新的它说,如果你想100%确定所有照片的痕迹都被删除,你应该擦除缓存。

但是,为了回答你的第一个问题,是否改变壁纸从系统存储当前壁纸的位置自动删除以前的壁纸:

是。或者,更准确地,以前的壁纸覆盖了新的壁纸,因为始终使用相同的文件名。当前壁纸存储在实际命名为"壁纸" 的图像文件中。选择一个新壁纸时,选择的图像文件被复制到标准位置( / / / system / seruble / seruble / < userid> /数据/数据/ com.android.settings / files ,取决于哪个版本)并给出相同的文件名,因此覆盖了以前的"壁纸" 文件。 (当然,这不会从原始位置删除图像,但您已从那里删除它。)

关于你的第二个问题,它并不完全清楚你的意思是"被砍被砍成的可能性" 。如果您想知道是否有物理访问手机的其他人可以访问该文件,那么答案就是只要手机未扎根,就无法浏览到当前的壁纸文件。但是,是的,有可能通过 hacking 访问文件,当然:可以root手机然后访问文件。但是第一个问题的答案使这个问题没有,因为只要图像存在于该系统位置,那些有手机的人都可以将其视为主屏幕背景,如果你改变壁纸然后图像是不再存放在那里。

 

As New-To-IT said, if you want to be 100% sure all traces of the photo are removed, you should wipe the cache.

However, to answer your first question, whether changing the wallpaper automatically deletes the previous wallpaper from the location where the system stores the current wallpaper:

Yes. Or, more accurately, the previous wallpaper is overwritten with the new one, because the same filename is always used. The current wallpaper is stored in an image file that's actually named "wallpaper". When you select a new wallpaper, the image file you select is copied to the standard location (either /data/system/users/<userid> or /data/data/com.android.settings/files, depending on which version) and given the same filename, so the previous "wallpaper" file is overwritten. (Of course, that doesn't delete the image from the original location, but you've already deleted it from there.)

Regarding your second question, it's not entirely clear what you mean by "possibility of being hacked". If you want to know whether anyone else who has physical access to the phone can access the file, the answer is that as long as the phone is not rooted, there's no way to browse to the current wallpaper file. But yes, there is a possibility of accessing the file by hacking, of course: it's possible to root the phone and then access the file. But the answer to the first question makes this question moot, because as long as the image is present in that system location, anyone who has the phone can plainly see it as the home screen background, and if you change the wallpaper then the image is no longer stored there.

As soon as you see the Samsung logo, release all keys/buttons. 5. Press on the Volume Down key to tab down to "wipe cache partition"  6. Once it is highlighted, press the Power button to select it. 7. On the next page, Press the Volume down button to highlight "yes" and press the    Power button to select it. 8. Wait for a few seconds for the phone to clear the data. 9. Press the Power button on the next page to select "reboot system now."  10.Wait for your phone to reboot.   

*这不会擦除存储在手机上的任何信息,图片,视频,应用程序,联系人等信息都将安全
