Is it still considered fraud to return a faulty product using the warranty from the newer product?

I recently bought a screen protector 2 days ago for my iPhone XS Max that has now cracked because I dropped it, and now wondering if it's fraud to return a previous screen protector from the same brand that is faulty due to faulty worksmanship. I lost the receipt for the faulty screen protector and was thinking of replacing the faulty one with the receipt from the newer screen protector.

The faulty screen protector has lost its hold around the screen, leading to air getting in inbetween and around the screen and protector.

This is my 3rd screen protector I bought from this company as the other 2 were faulty, and I don't want to spend an other $80 on a screen protector when the previous 2 were faulty.

Added (1). Keeping in mind that the screen I bought before the new screen protector was faulty and that I only lost the receipt for the previous screen protector. I don't want to waste another $80 on a screen protector.

Added (2). My new screen protector I dropped isn't the faulty one! It's the one before that is the one with the faulty worksmanship as the glue had weakened around the edges and sides.

How do I use a different companies SIM card in an iPhone?

My parents got me an iPhone 6 for Christmas this year and were told it was unlocked, but after putting in the SIM card, we found out it wasn't. So when I went to see who the carrier was, so we could get it unlocked, it said it was the carrier we use. Anyone know what's going on?

My sister went on date 6 hours ago and hasn't returned. Do I wait longer before calling emergency services?

My dearest sister awoke this morning to prepare for an upcoming date with someone she met through mutual friends. SHE HAS NEVER MET WITH HIM IN PERSON…
at first we were excited for her assuming it would be nothing but a harmless little date. She left at 7:45am arriving at the location (a resort where they were having brunch and hiking) around 9am. They had planned to eat some brunch and then go for a hike of which the length was not decided yet. She had texted our mother at 10:00 o'clock saying that he was great and they had a good discussion. They had yet to go hiking. WE HAVE NOT HEARD FROM HER SINCE 10AM. We have not tried to contact her as not to intervene on her date. It has been over 6 hours now and I'm concerned for her safety. My father and I have repeatedly checked find my iPhone but her iPhone stays in the same location. We're fearful of what has happened to our darling sister. I'm unsure if I should wait a little while longer or try to contact her. What do you think?
