performance

Quad-core 1.3 GHz Cortex-A53, 2GB RAMLow-power 2014-era CPU with minimal RAM means this phone struggles with modern apps, multitasking, and anything beyond basic calls, messages, and light web use.

battery

2350 mAh, removable batteryAbout 4 to 5 hours of screen-on time with typical use; you can swap in a fresh battery instantly without waiting to charge, which helps on long days without power access.

display

4.0" TN TFT, 480x854 pixels, 245 ppiTiny, low-resolution screen with poor viewing angles and dim backlight makes reading text and viewing photos noticeably cramped and blurry compared to modern phones.

camera

5MP main, 2MP selfie, LED flash5-megapixel sensor produces soft, low-detail photos usable only for records of faces or documents; selfies are barely sharp enough for messaging.

connectivity

LTE bands 1/3/5/7/8/19/20/40, Wi-Fi 802.11 b/g/nLTE and older Wi-Fi standard cover most regions but will be slower than modern networks; no 5G, NFC, or dual-band Wi-Fi.
