The display on the Nokia Asha 503 is a 3" TFT unit of QVGA (240 x 320) resolution, which boils down to around 133ppi - the same as the one we saw on the Asha 501. It is of the capacitive variety with multi-touch support, and this time around it even boasts Gorilla Glass 2.
Colors aren't too great and contrast is limited, but you can't expect much better in this price range. The screen is reasonably bright for an LCD, though its viewing angles are less than stellar. Size may be an issue, as well as resolution, but the response to user input is great.
Our test confirmed the mediocre contrast levels at both full brightness and 50%.

The pixel arrangement is standard RGB - it's an LCD screen so you wouldn't expect anything less.
Nokia Asha 503 display matrix next to Asha 501's
All hardware controls of the Nokia Asha 503 are on the right side. There you can find the power/lock key and the volume rocker. Both are made of nice matte plastic, offer great tactile feedback and are very easy to locate by touch.
There is nothing on the left side of the Nokia Asha 503.
At the top there's the microUSB port for charging and data connections. The 3.5 mm headphones jack is also around. Unlike the Asha 501, Nokia has decided not to use the old-gen charging port here.
The bottom features the microphone pinhole only.
Removing the back cover is easy - a push on the nub at the bottom will make the phone's bottom part pop out of the shell. Not as easy as on the Asha 501 though - the slippery surface won't allow a secure hold, so a little extra caution is in order.
You can then go on and take the phone out. Once the battery cover is gone you can access the 1200 mAh Li-Ion battery and the SIM slot beneath. The hot-swappable microSD is on the side.
The battery life of the Asha 503 is quoted at 840 hours of stand-by and 12 hours of calls over 2G networks or just 4 hours and 30 minutes in a 3G network.
