How damaging is it to keep the 2024 Razr+ open in your pocket?

So I'm going through a real rigamarole with Motorola right now. I have a 2024 Razr+ that's only 4 months old, and the other day it broke. If I close the phone, when I reopen it the screen doesn't turn back on. After about 5-20 minutes, the screen will start flickering and then eventually it turns on and works normal. And it continues to work normally as long as I don't close it. According to my Google research, it's most likely caused by damage to the internal ribbon flex cable.

So since it's in warranty and the repair shop near me confirmed they work with Razrs, I went online to make a warranty claim so I can get it repaired. But my IMEI number is associated with a completely different phone model that I've never owned in their system, and to make it even worse the imaginary phone associated with my IMEI has been out of warranty since about a year before I actually bought my phone. I called them and after hours of me talking to them and trying to convince them that the phone associated with my IMEI is not the phone I have, they finally let me email them my receipt from the AT&T store I got it from as a proof of purchase. They said they'll email me when their IT department fixes the discrepancy with my IMEI number, and once they do that I can make a warranty claim. However they said they'll take anywhere from 48-72 hours.

So in the meantime, I have to keep my Razr open 24/7 for it to work normally. Including when it's in my pocket. Since the phone is already damaged, and I need my phone for my job, I'm pretty paranoid about keeping it open all the time. Is this a really stupid idea? Would it be smarter to just go buy a cheap refurbished phone and use that in the meantime? Money is really tight for me at the moment so even a $50 refurbished phone would make a dent in my bank account that I'd rather not make unless I had to. I've kept the phone open all day today, including while in my pocket, and it's worked normally but I'm so nervous the screen is just going to completely die on me due to it staying open.

This is my second Razr+ 2024, I got my first one back in 2024 and it broke after I dropped it in May of this year but AT&T was able to replace it with the same model for basically no money even though the warranty was expired. The fact that this one is already breaking after only four months despite me being really careful with it, keeping it in a sturdy case, and only dropping it once two months ago is making me feel like my next phone might have to be a slab phone. I've used flip phones since 2020 and I've grown so accustomed to the form factor that the idea of going back to a slab makes me so sad, I really love the flips and there's a lot of things I've grown used to doing with my phone that I couldn't do with a slab.

So basically: is it so dangerous to keep the phone open 24/7 that it's worth it to get a temporary phone until I'm able to send this one in for repair, or is it safe enough at least to go a few days with it always open until I'm able to get it repaired?
