Your phone didn't get slow by accident.

After 2-3 years, Android phones slow down for real, measurable reasons: storage chips physically degrade from thousands of write cycles. Your battery's internal resistance rises, causing the CPU to throttle itself by 30-50%. Samsung, Xiaomi, and other manufacturers pre-install dozens of apps that consume RAM, CPU, and battery — even when you never open them.

A factory reset won't fix hardware wear. "Cleaner" apps on the Play Store are scams that show fake scans and serve you ads.

Android Doctor is different. It runs real diagnostics on your actual hardware and tells you exactly what's wrong.

WHAT IT CHECKS
• Battery health — capacity percentage, charge cycle count, temperature, thermal throttling detection
• Storage health — NAND flash wear level (eMMC/UFS), disk space, storage type identification
• Memory — total/used/available RAM, swap pressure, per-process breakdown
• CPU — load average, top resource-consuming processes, thermal zone temperatures
• Bloatware — scans installed packages against a database of 113 known bloatware packages across Samsung, Xiaomi, Oppo, Vivo, OnePlus, Huawei, and Google devices

WHAT IT DOES
• Diagnose — full system scan with scored categories (0-100) and root cause attribution (hardware vs software vs thermal)
• Fix — safely disable bloatware, optimize animation scales, limit background processes, restrict battery-draining apps
• Benchmark — measure cold app launch times, storage I/O speed, before/after comparison
• Battery analysis — detailed drain breakdown with charge cycle tracking

KEY FEATURES
• Root cause attribution — tells you if your slowdown is 40% hardware, 35% software, 25% thermal
• Before/after proof — benchmark your phone, apply fixes, benchmark again to see the improvement
• Fully reversible — every change is snapshotted. One tap to undo everything
• No root required — works on any Android 8.0+ device
• No ads, no tracking, no cloud — 100% on-device
• 2.3 MB app size — lightweight by design

SUPPORTED MANUFACTURERS
Samsung (30 packages), Xiaomi/MIUI (25), Oppo/ColorOS (14), Vivo (10), OnePlus (5), Huawei (11), Google/Pixel (8), plus common pre-installs like Facebook Services and OneDrive.

For advanced features (package management, storage health reading), install Shizuku from the Play Store to grant enhanced permissions without root.
