I've actually been the proud owner of a Huawei Mate 10 Pro for more than a year now, but it hasn't really been working well for a few months. My problem is that when I call someone, the person never hears me the 1st time, I have to hang up and call again so that they finally hear me. I always understand the person on the other end though. This weekend, and once before, this unfortunately didn't work, the person across the phone didn't hear me even after 5 times of calling.... No matter if I delete this special "Wipe Cache Partition" or not, it just doesn't work anymore. Does anyone here also have this problem or know another solution apart from clearing the cache? :(
