Around half of owners will get the update in the next seven days, with the remainder over the following seven days.
The technician in the Nokia Center recommended me that the next time it's better that I don't try to update the phone because it fails a lot of times.
(Also said that there are no benefits in updating it... But as i have seen on the net, that kind of error happens a lot, leaving the mobile "dead" and the only way to repair it, is sending the mobile to Nokia...
The presence of Updates on Nokia Servers does not mean that the FOTA update will be delivered very shortly as both these are pretty different methods.
Care Suite flashes the full firmware files whereas FOTA updates only contain the required update files and hence are pretty light-weight as compared to the Full Flash files.
The problem persists even after the update, that was said to address the touchscreen lags.
