Does anyone else's Photon randomly have the optical sensor at the back fail when starting a print?

I'd say one in every 20-30 prints or so, I'll start printing and the bed will lower slowly as usual. However, upon reaching the vat the optical sensor seems to be ignored (no stopping or beeping) and the bed begins pushing into the screen making a worrying grinding sound. I usually rush to stop the print, but not sure what would happen if I just left it unattended.

I'm on the latest firmware (had it on previous firmwares too). Nothing blocking the optical sensor and it happens on my relatively old (12+mo) and new (1 mo) Photons. Anyone else have this or know a way to avoid it besides hovering at the start and panic-cancelling?

Purchased second Photon last week to go along with my first so that I could print twice as much in the same time. Been having massive problems with it compared to my first Photon. Same resin, same times, same STL prints fine on one printer and fails ~75% on the other.

Had original Photon for about a year now and I'd say 90-100% success rate (just human error now and then from bad supports) so not a new user, and know what I'm doing. Leveled and re-leveled, checked FEP tightness, firmware update to latest, checked build plate flat, etc.

Finally had an STL that consistently failed (would either come out with a weird surface finish, or would not stick to the front of the bed and warp). Looking at the LCD, I noticed the closest half of the LCD is wobbling (video attached - left half of the centered print). This doesn't appear to happen on the exposure test - just this print (and randomly in the middle of other prints).Wobbling gets worse as the print goes on.

Figured I would post here to see if there was anything I should check. So far I've checked LCD cable seating, positioning, etc. Is this a faulty LCD and needs replacing? Anything else I should try internally? I haven't removed the LCD to check the cable on that end as I'm just worried from the amount of broke-my-LCD-horror stories on here and would rather just return and replace from Amazon if it's likely to be that.

Is it true that the green sticker on the side of the Photon means it's a refurbishment (any kind of explanation or proof would be great)?

Just bought myself a second Photon from Amazon (Prime, described as new) so that I can print two things at once and this new one has two green stickers, one slightly darker than the other, on the side.

My original didn't have these and I had read these stickers mean its a refurbished, resold printer - is this true? With the life of the LEDs/screens/etc. I really want a brand new model - not a refurbished return.

If true, what's the opinion on refurbs. Should I send it back and request a new, non-refurbished printer?
