On the side of storage, 16GB become useful 12 GB for the system including 4 and 8 other files but it is very easy to expand capacity with a MicroSD card which can move apps.
The Android system is almost very open plain (almost no overlay manufacturer) and you can enjoy all the features and qualities of this system (application management and storage, fluidity, backups among others ...).
By cons, no proposed by Wiko management software (updates, file transfers, backups) as found in leading brands but there are common alternatives to all Android.
On the side of autonomy, like all smartphones: when you play a lot with (this is the case when you just had her "toy"), the battery can empty in one day but it takes 2/3 days without recharging being reasonable (Bluetooth, WiFi, GPS, games, high energy consumption).
Remains to be seen what comes of it in time to the level of reliability (2 year warranty but quality of service?) And system updates.
Anyway the price / quality ratio seems to be good a priori. RDV in a few months ...
And always the quality of service like Amazon cherry.
Edit 01/03/2014
After several months of daily use RAS. There is no fault to deplore, and there is never any lag or crash, regardless of the application used (including games). I tested the capabilities of "smart gesture" and not a problem at this level there either although I find it a little too "gadget".
The audio portion remains disappointing and with all possible trials we come to something acceptable without further (compared to other terminals).
The dual SIM also works well and I am not disappointed by the battery life.
There was a small OTA update system by Wiko but for now the importer does not seem determined to do more.
Wiko Stairway remains a good plan compared to big brands (equivalent to S. Galaxy S3 for example but cheaper).
