So funny you ask this — last month I was rushing for the train and my Razr+ slid out of its plastic shell onto the platform. The case failed to protect the device because it was not secure. I immediately switched to a setup that stays attached to the hardware. Buy these two items:

• VRS Design Terra Guard Modern for Razr+ 2025 ($35). This uses a hinge protection system that keeps the two halves of the case connected so they cannot slide off.
• Supershieldz Tempered Glass Screen Protector for Razr+ 2025 ($10). It provides a thick layer of protection for the external display. Your total spend will be under $50. The takeaway is to prioritize cases with integrated hinge protection to ensure the two pieces of the case remain joined to the phone at all times.

Rarely post but had to chime in. These items fit your $80 budget:

• Spigen Air Skin Shield for Razr+ 2025
• amFilm Tempered Glass 2-Pack Adhesive strips inside prevent sliding.

I had the exact same issue with my first case sliding off constantly on my daily commute, and ngl it almost cost me my screen when it slipped right off my lap onto the concrete. I learned the hard way that cheap plastic clips just dont cut it for these folding hinge designs. I ended up switching to my current setup which uses this micro-suction adhesive strip tech inside the shell to actually grip the phone frame. Honestly it made a massive difference and now the thing is practically glued on. If you want to keep that outer screen safe you absolutely need something with that inner grip stuff or it WILL slide off eventually...

Building on the earlier suggestion, do you need full hinge protection — or wait, maybe just a cheap grip? 1. Caseology Nano Pop Razr+ 2025 ($25)
