Design and Build
In terms of design, the Philips S309 is straightforward and functional. Its dimensions of 127.6 x 64.7 x 10.8 mm make it compact and easy to handle, fitting comfortably in one hand. Weighing 127 grams, it's lightweight for an Android device from 2015, which contributes to its portability. The phone features a plastic exterior, typical of budget models, available in black and red, offering users a subtle choice in appearance. The dual SIM feature, using Mini-SIM cards, allows users to take advantage of multiple networks.
