The Nokia Lumia 525 has been bouncing around in rumorland by its codename "Glee" for quite a while now. The upcoming device will be the replacement for the hugely successful Lumia 520, and naturally, the smartphone is set to compete strongly in the midrange sector.
We now have the first leaked images of the Lumia 520 successor, which comes from China's mobile certification agency TENAA, which is equivalent to the FCC in the US.
According to the certification, the Lumia 525 is said to be a music oriented smartphone. The hardware specifications of the device are rumored to be similar to what we found on the Lumia 520, except for the RAM being boosted from 512MB to 1GB.
Sources say the Nokia Lumia 525 will be announced by the end of the year and the smartphone will be available in White, Yellow, Black and Orange color options.
