Hello,
Thank you for the reports.
Currently we’re suspecting that in the reported cases the dust may have entered through the front camera assembly housing, or in addition through top microphone hole housing, which is missing a rubber sealing (which are supposed to be there) due to a manufacturing assembly error of the unit in case.
Let us firstly analyse what is the root cause and which manufacturing dates are affected:
The ramp-up of the mass production for the sales batch Batch #1 has included four independent manufacturing runs on separate production days. All the units prepared for the Day1 event were from the first two mass manufacturing runs, difference being the colour The Orange and Kaamos Black.
Thus those affected, if you wish, kindly drop a comment below whether you got your device from the Jolla Phone Day1 event in Helsinki, or it was mailed to you between July 9 - 29, and in which colour you got your Jolla Phone. Sharing the information will help us (and other customers) to faster iterate and potentially isolate the issue to a particular production day.
Once we have analysed the issue and root cause, we will come back with the corrective solution and process for the affected customers. Meanwhile, we DO NOT recommend DIY fix the unit and rather kindly wait for the solution which we will provide.
Jolla Phone has a 2-year warranty for hardware defects.
