Which Lumia do you own?
While we are working to make Windows 10 ready for other Lumia devices, the following is a list for Lumia Smartphones that will receive the free upgrade when available: Lumia 430, Lumia 532, Lumia 535, Lumia 540, Lumia 635 (1GM RAM) , Lumia 640, Lumia 640 XL, Lumia 735, Lumia 830, and Lumia 930. Features may vary from device to device. 8 GB of internal space required.
Looking at the table, in the image above, it may seem that the greater the available storage, the greater the space that Windows 10 Mobile (W10M) occupies. However, it is important to remember that any device always reserves some internal space for itself, to perform its basic functions, which would indicate that the update actually occupies approximately 4,5 GB of space.
ATTENTION:
- 8GB = 7,5GB - 4,5 = 3GB
- 16GB = 14,5 - 4,5 = 10 GB
- 32GB = 29,5 - 4,5 = 25 GB
The first value on each line is the total storage space, while the second indicates approximately the space actually available for use. The 4,5 GB is the total occupied by W10M and the last value is what is left over after the system is properly installed.
