About this app
Does your phone really stream Netflix in HD or 4K — or is it secretly capped at SD? The answer comes down to one thing most people never check: your device's Widevine DRM security level.
Widevine DRM Check reads that level straight from Android and instantly shows you what it means for every major streaming app.
▶ INSTANT WIDEVINE CHECK
One tap reveals whether your device is Widevine L1, L2 or L3 — the hardware security tier streaming services use to decide your maximum video quality.
▶ SEE YOUR REAL STREAMING QUALITY
Get a clear, per-app breakdown of the resolution you actually receive on:
• Netflix
• Disney+
• Max (HBO)
• Prime Video
• Apple TV+
• Spotify
L1 devices unlock Full HD and 4K. L3 devices are capped at SD or 540p — no matter how good your screen is.
▶ 4K & HDCP REQUIREMENTS
Even on an L1 phone, 4K needs an HDCP 2.2+ display and connection. The app checks your maximum and currently connected HDCP level, so you know exactly what is blocking 4K.
▶ FULL TECHNICAL DETAILS
For enthusiasts and pros: view the raw MediaDrm properties — Widevine vendor, version, system ID, security level, supported algorithms, max HDCP and more.
▶ 100% ON-DEVICE & PRIVATE
The check runs entirely on your phone. No sign-in, no streaming account needed, and none of your check data ever leaves your device.
WHY YOUR WIDEVINE LEVEL MATTERS
Netflix, Disney+, Max, Prime Video and most premium apps use Widevine DRM to protect their content. Hardware-backed Widevine (L1) decrypts video inside a secure enclave and unlocks the highest resolutions. Software-only Widevine (L3) is treated as a lower trust tier and is capped at SD/540p. The level is fixed in hardware at manufacture — no app, update or root tweak can raise L3 to L1 — so it pays to know which one you have before you buy a 4K plan or a new phone.
PERFECT FOR
• Buying a new phone for streaming
• Checking a used or budget phone before you pay
• Troubleshooting why Netflix won't play in HD or 4K
• Comparing devices for premium video
• Tech fans who want the raw DRM data
