I bought a Leagoo Kiicaa mix in 2017. Both fingerprint reader and type C charger broke after a month or less. Service from retailer or Leagoo was non-existant. Credit card refused charge back so decided to repair myself as found teardown video on net. On disassembly I found the charge socket was unsupported unlike the official Leagoo teardown video which had a small supporting metal bracket. The Chinese site I bought the replacement Leagoo type C socket from had sold over 130 of them worldwide. So clearly a common manufacturing fault where they left out a necessary support. I didn't worry about fixing the fingerprint scanner and I made sure to be super careful plugging charger in. Stopped using it as a phone as no one could hear me. Bluetooth was virtually useless,front camera required flipping phone, OTG stopped working after about 2 uses. I ended up just using it for watching YT videos in bed if I couldn't sleep. Even then in that quiet setting the sound was barely audible and screen was visually fatiguing. Disappointing purchase.
