tab s3 sm t820 time problem

[anon125]

we have 3 different samsung tablets.
without internet on, 2 remember the time when i switch them on.
tab s3 sm t820 9.7 does not remember the time.

is this a faulty tablet?
or a faulty design?
samsung do not know.
their repair folks do not know.

anyone have one of these? please disconnect the internet, leave it disconnected, switch the tablet off, then on again and see if the time is correct without the internet.
thanks

Is the time a certain amount of hours/minutes off every time, or is it a random time?

it seems to always go to the same date, but the time is nonsense, - looks like random time.
thanks

Would that date happen to be January 1, 1970?

hopefully this will work!
Steps to Hard Reset:

• Turn your Galaxy Tab 3 off.
• Now Press & hold the Volume Up, Power and Home buttons together until you see an Android lying on its back.
• Use the volume keys to scroll down to Wipe Data/Factory Reset and use the Power button to confirm.
