The most of the Xperia Z1/Z1c/Z2/Z2c/Z3/Z3c users know the fact that when the bootloader is unlocked the device loses the 'DRM keys' and some of the features at the same time.This is causing bad camera performance and the X-Reality/Bravia/Vivid is stops working.Sony confirmed this fact at the Xperia Z3 but the Z1/Z2 users were not indicated about this and some of the users unlocked their bootloaders without knowing this.The request of this petition is to make a way to keep the DRM keys and all the features with an unlocked bootloader or just do something for the users who already lost it to recover their features and get fully working xperia devices.Sony's motto is :Details makes the difference. so we would be gald to have phones with the best details .Hope Sony can make something about this.
