I have a Huawei P smart phone from O2. Its less than 6 months old and is not working properly, despite a factory reset. I took it to our local store today but there was no one there that could help except advising I contacted a Guru or asking me to pay the balance for an upgraded phone ( not helpful). I cant find anything on the O2 site that lets me do that. The phone is still in warranty and needs looking at.
any help is appreciated
Personally, I'd contact Huawei directly https://consumer.huawei.com/uk/contact-us/
