I bought a Cubot X90 from Ali Express
I bought a Cubot X90 from Ali Express. Phone worked well initially for a week and charged promptly and quickly. After a week it suddenly went into a perpetual re-boot loop, screen flashing and vibrating which drained the battery over the course of a few of hours. On recharging it worked OK for a couple of days and then did the same thing all over again and again.The intervals when it was actually working were getting progressively shorter and shorter. After a few further repeats I'd had enough and decided in the short interval when it was working to do a full factory reset. When charged and powered up again it was still re-boot looping so the phone had clearly left the factory with an inherent fault. No point contacting Cubot as their phone warranty is worthless. Phone should never have left the factory in that state. Never buy a Cubot phone, unless you want a very expensive paperweight.
