The phone comes with the 4.7 inches looks and feels good in the one hand use and in Windows 10 there is a feature called one hand used we can use the phone in one hand easily.
Value of money is very poor if you buy this product because in this price you can get Lumia 535 which have many features than this Lumia 550 I personally recommend you to go for the Lumia 535 if you are going to buy the Lumia 550. Or go to the Android device which comes many features and extra Ram and also with the internal memory.
Not worth to buy because in this range there are many phones comes with the many features and extra internal memory and also extra Ram.
There is nothing new in this phone compare Italy Windows 8.1 and Windows 10 there is a many features in Android then Windows 10 there are many apps in Android which not support in this Windows 10.
If you want stable apps and stable software go for the Android device because Windows 10 do not have many apps like Android supports.
