I was so happy with my p smart phone I bought just after Christmas. It stayed charged for days. Everything worked perfectly. I downloaded the upgrade only because I thought there were important security patches. I am so disappointed. The first thing I noticed that was wrong after the upgrade was the sound. I always turn the sound off at night. I used to use the button on the side and then press silent mode. Now I have to go in to settings to press silent mode. But it doesn't work! I was woken up twice in the night by media noises. Every time I want to put the sound on or off I have to go in to settings and drag the sound bars fully on or fully off for each feature, alarm, media, calls etc because it does not automatically change them as before. The next thing which doesn't work properly now is charging. Before it charged so quickly it was impressive. Now it often won't charge at all. And it drains quickly. What exactly was the point of this upgrade? The icon colours have changed and look more tacky which I would accept if it weren't for these other important issues. To be honest I am shocked that Huawei would allow an update to be rolled out to the whole world with these bugs. To some of us phones are a really important means of keeping in touch and we simply need them to work! They should enhance daily life not create stress and waste time. Now I am seriously going to have to think about getting a different phone. I refused to get an iPhone but perhaps people are right about it! So disappointed.
