Hi Rick.
Thank you for reaching out regarding Samsung - 27.8 cu. ft. 4-Door French Door Refrigerator with Food Showcase Fingerprint Resistant on how to remove the bottom glass. Regarding your concern, to be able to remove the bottom glass, please follow these steps:
• To remove a shelf, fully open the corresponding door. Hold the front of
the shelf, and then gently lift up and slide out
• To reinsert, hold the shelf at an angle, so the front is higher than the back, and then insert the top hook into the top shelf notch. Then, lower the shelf and
insert the bottom shelf hook into the bottom shelf notch.
I suggest you check this link to your user manual for assistance. Please go to page 67.
