My huawei phone is not receiving text messages? My huawei Y3II was working fine and receiving messages without any problem. But, one day I realized that one or two weeks have been passed and I did not got any text message. Then I checked by sending message from another phone but, I did not received. I have not done anything with my phone then, what could be the problem.
Factory Reset has solved my problem. This also solved my second problem which was automatically turning off sometimes and then showing 'Starting apps' and taking too much time on it.  

->  First of all I saved all my data to sd card and then switched off the phone and took out my sd card.

-> Then I reached to options by pressing power button and volume up button and releasing power button when logo is shown while continuing pressing volume up button.

-> Then I selected wipe data/factory reset option. It took just a few seconds to complete factory reset and then I rebooted the phone.
