If you knew Sony, you would know they are imbeciles that are really really saving/making money on everything. I actually hate them and never buy their products, because this attitude is part of their company culture. However by accident they provide the AOSP and I am forced to use the crap of the phone.
I would bet, many of the bugs we have with SFOS are because of those “shortcuts”. Very pity!
I wish Jolla would pick up another manufacturer like FreePhone or similar.
