Lumia 540 is good for office work this phone is good presenting phone the RAM of phone is not much 1GB . The Phone body looks good and simple. This lumia phone hangs if memory is full and the screen does not work if a little bit of moisture get on the screen . From my view the lumia phone is not good for today’s generation as the lumia store does not allow several game like coc, pokemon go, etc. The camera is good but picsels destroyes imidiately . The best thing about the phone is it works smoothly and give a good look in our hand, the phone body does not get affected from a small jurks.
