So I've been using foldables for years now and ngl, the anxiety about those screens is totally real! In my experience, choosing the right protection is basically mandatory if you wanna keep the resale value high. Over the years I've tried many brands, but for the OnePlus Open, you gotta be careful with the hinge clearance and case fitment. For your situation, here's what I recommend: * Outer Display: Go with the OnePlus+Open+Tempered+Glass+Screen+Protector&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">dbrand OnePlus Open Tempered Glass Screen Protector. It's super high-quality and fits perfectly with most cases cuz it leaves just enough of a gap around the edges.
* Inner Display: I'd suggest the OnePlus+Open+Matte+Film&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">Healing Shield OnePlus Open Matte Film. It cuts that reflection down significantly and feels much smoother than the stock film. Basically, just take ur time with the inner install... it can be tricky lol. But yeah, these two are solid and won't lift when you pop a case on. gl!

Curious about one thing: what case are you rocking?

tbh Orzero is safer, but tell me ur case!

Just catching up! Tbh, I went through this last month cuz I didn't wanna spend a ton after buying the phone. I learned: - *Edges* matter: If ur glass is too wide, cases will lift it.
- Matte films are softer, so they absorb glare but scratch easier. I've been using:
• OnePlus+Open+3-Pack&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">Supershieldz Tempered Glass Screen Protector for OnePlus Open 3-Pack
• OnePlus+Open&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">IQ Shield Matte Film Screen Protector for OnePlus Open Pretty happy with the value!

For your situation: - OnePlus+Open+Prism+Screen+Protector&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">dbrand OnePlus Open Prism Screen Protector (shatter-resistant)

Totally agree with the points about edge clearance! If your glass is even a hair too wide, the case lip will just lift it right up... it's basically the most frustrating thing ever. Since you're looking into doing this yourself, here are a few warnings from my own DIY trial-and-error as someone who's obsessed with keeping my gear mint: * **Inner Screen Factory Seal:** Honestly, be really careful with that inner film. These foldables usually come with a factory-applied protector that's pretty much essential to the screen's integrity. If you DIY a replacement and accidentally pull up the actual display layer, you're looking at a super expensive repair. I'm pretty sure it can void the warranty in some regions too???
* **The Steam Trick:** If you're doing the outer screen at home, definitely do it in a steamy bathroom. It's the best way to keep micro-dust from getting trapped under the glass—it's worked for me every time!!!
* **Alignment is Key:** Before you actually drop the glass on, try a "dry fit" with the case *on* first. It helps you see exactly how much wiggle room you have on the hinge side so you don't overlap. It’s definitely a fun project if you like doing things yourself, but it's a bit high-stakes compared to a normal phone lol!

So, summarizing what everyone's said: fitment is basically the biggest hurdle and you definitely shouldn't touch that inner factory film unless it starts bubbling on its own. From a long-term ownership perspective, you also need to think about oleophobic coating longevity and VLT (Visible Light Transmission) ratings. After six months of heavy use, cheap protectors lose their hydrophobic properties and just become smudge magnets. Technically speaking, you want something with a high-grade OCA (Optically Clear Adhesive) to avoid lifting. Here are a few alternatives that haven't been mentioned: * Whitestone Dome Glass EZ: These have great optical clarity and the adhesive is high-quality enough that it won't yellow over time.
* Ringke Invisible Defender: This is a solid choice because they leave a very specific 1.2mm tolerance gap for case lips, which solves the lifting issue.
* Gadget Guard Black Ice: Honestly, their tempered glass has one of the better Mohs scale performance ratings for scratch resistance on the outer display. Just a heads up, even the best matte films will slightly diffuse the sub-pixel arrangement on that beautiful inner display, so there's always a slight trade-off in sharpness for that glare reduction.
