Vivo

In 2017 engineers from ifixit.com disassembled and analysed a range of smartphones, tablets and laptops, awarding each a repairability score between one and ten. Ten is the easiest to repair. A device with a perfect score will be relatively inexpensive to repair because it is easy to disassemble and has a service manual available. Points are docked based on the difficulty of opening the device, the types of fasteners found inside, and the complexity involved in replacing major components. Points are awarded for upgradability, use of non-proprietary tools for servicing, and component modularity. Products by this company scored between 6 and 7 points.
