OSCAL has added two new smartphones to the FLAT series on the Official Store: the FLAT 3C and the FLAT 3C Mini. The pair splits the lineup along a clean line — the FLAT 3C is a full-featured daily driver with a 6.56-inch display and 5000mAh battery, while the FLAT 3C Mini is a compact 5-inch phone built around one-hand use, a removable battery, and accessibility.
FLAT 3C: The Everyday Android 16 Workhorse
The FLAT 3C runs DokeOS 5.0 on Android 16 and targets the widest possible audience — teens, seniors, and anyone who wants a dependable phone without the flagship markup. A 6.56-inch HD+ IPS display with 180Hz touch sampling and 430-nit brightness handles movies, social scrolling, and video calls. Three eye-comfort modes (Reading, Night Light, Dark) reduce strain during long sessions.
The 5000mAh battery is the headline. Combined with daytime deep power-saving and system-level optimization, OSCAL claims up to 23% longer everyday battery life and 71% longer nighttime standby. For most users, that means a full day with room to spare.
Memory comes as 4GB physical plus up to 12GB expansion for 16GB total. Storage is 128GB built-in with 2TB TF card support. The 32MP AI camera handles everyday photography, and the phone ships in Orange, Black, and Blue.
FLAT 3C Mini: Small Screen, Removable Battery, Senior-Friendly
The FLAT 3C Mini is the opposite philosophy. At 5 inches and 158.5 grams, it is built for one-hand use and easy pocketing. Android 16 Go keeps the interface fast and uncluttered on modest hardware.
Its most distinctive feature is the removable 3000mAh battery. When it runs low, swap in a spare and keep going — no waiting beside a charger. That alone makes it a strong choice for travel, long commutes, and older users who do not want to be tethered to a cable.
Accessibility is a first-class feature, not an afterthought. Adjustable display magnification, large text, high-contrast rendering, and TalkBack voice guidance make the Mini usable for aging eyes and hands. Loud ringtones and strong vibration reduce missed calls. A dedicated side button launches the camera with a double press.

The FLAT 3C is the default recommendation for anyone who wants a full Android experience. The FLAT 3C Mini earns its place as a second phone, a first phone for older family members, or a travel companion that never leaves you stranded with a dead sealed battery.
