I bought a Nokia 5.3 with huge expectations. I have been left extremely disappointed with the product and would not recommend it. The phone freezes momentarily when making calls through WhatsApp. As it was under warranty, my network provider arranged for the phone to be checked and it's motherboard was replaced as it is still under warranty. The latest software was also uploaded. Inspite of these repairs, the phone still freezes for a few seconds when I make WhatsApp calls. This is a huge inconvenience and I am going to go back to my old Huawei phone which I feel is a lot better quality phone. I asked my network provider if they would replace the phone for me but they declined as I crossed the 28 day mark for returns. I don't blame them. I feel Nokia need to do something to improve the quality of their products or customers are soon going to realise that the product is not as good as the brand name.
