This oppo joi r1001 was brought to us after the touch screen randomly out of control, moving around and causing other being touched makes another stressed out. This happened after our customer rooted the device.
So we had already done flashing the stock ROM and the upgrade to the latest Colour OS software OTA by offline method. and the problem persist and the launcher also randomly crashed, but finally we notice that after a clean upgrade, the previous data and cache should be wipe out from the phone memory by doing hard reset If it wasn’t remove so that the new OS installed will use the previous data and this what caused the system crash. It also make sense you dont need to flash new ROM to solved this problem instead of tried wiping old data and cache, if unresolved then you can downgrade to stock rom and then upgrade to the latest software version:
