This started maybe 2 or 3 days ago. When I went to close the 3DS to put it in sleep mode it turned itself off. I turn it back on and closed it and went to sleep mode. Now every time I close the 3DS it turns itself off. Yesterday I noticed that the top screen was stuck on the brightest setting. I can still change the bottom screen brightness.
Does anyone have any ideas on why this happens? Any possible solutions? I guess I could just turn it off every time, but then I'll miss out on streetpass and spotpass.
Thanks
