Speeding up your 3G/LTE networks by the following tips:
- Contact your network provider to check if there is problem with mobile network.
- Install your SIM card on another phone to check if there is problem with your phone.
- Access to Safe Mode, press and hold the power key then tap Power Off > OK. If your phone is working well in Safe Mode, that means there might be third-party apps that cause malfunction when you use in Normal mode. Please restart your phone and check again.
