Android screenshots save location and name

I have summarized the information related to the screenshots of the smartphone that I have checked by my phone and friends.

For reference, the source code for Android screenshots can be found at the link below.

https://github.com/aosp-mirror/platform_frameworks_base/blob/master/packages/SystemUI/src/com/android/systemui/screenshot/GlobalScreenshot.java#L97

	Device	OS Version	Directory	File name
1	Nexus 5x	8.0	Pictures/Screenshots	Screenshot_yyyyMMdd-HHmmss.png
2	Galaxy S8	8.0	DCIM/Screenshots	Screenshot_yyyyMMdd-HHmmss.png
3	Galaxy S6	7.0	DCIM/Screenshots	Screenshot_yyyyMMdd-HHmmss.png
4	Galaxy Note5	7.0	DCIM/Screenshots	Screenshot_yyyyMMdd-HHmmss.png
5	Galaxy S7	6.0	DCIM/Screenshots	Screenshot_yyyyMMdd-HHmmss.png
6	LG G4	6.0	Pictures/Screenshots	Screenshot_yyyy-MM-dd-HH-mm-ss.png
7	LG G2	5.0	Pictures/Screenshots	Screenshot_yyyy-MM-dd-HH-mm-ss.png
8	Galaxy S3	4.4	Pictures/Screenshots	Screenshot_yyyy-MM-dd-HH-mm-ss.png
9	Galaxy S2	4.1	Pictures/Screenshots	Screenshot_yyyy-MM-dd-HH-mm-ss.png

The name of the folder where the screenshot is stored is the same as "Screenshots". However, the upper directory seems to be set to the "DCIM" directory for Samsung phones (except for older phones). In the source code, the parent directory is obtained through the following code.

Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);

Although the file name of the recently released LG phone is not confirmed, it seems to omit the '-' separator in each date and time field. The source code for this part is shown below.

String imageDate = new SimpleDateFormat("yyyyMMdd-HHmmss").format(new Date(mImageTime));
