Help with old android image naming sequence

Old android photo name sequence

Help decoding file names

Example. I want to see if a file name aligns with a time / date in which the photos were taken. Generally a device has a sequence in which it labels like MMYYDDHM.JPG. The metadata from these files is stripped. We only have the names to go off of. The photos were taken on a 2015-2017 LG model android phone with metro pcs.

10206299612608799.jpg, 10206299612768803.jpg, 10206299612888806.jpg

Some context, the photos are all of the same object at what appears to be taken in a sequence.

The last part of the file name (608799, 776803, 888806) is the only part that changes.

The only data I have is the date that they were potentially taken to compare. Date: 09/24/17.

Other files i have for comparison

Anyone able to determine when the three i listed above were taken?
