Samsung Galaxy Note 4 User Manual

Yep, I am. When I try updating the WhatsApp or downloading it, it informs me that the version is not compatible with my device.

Thanxx.

Hi ssmdung. The latest WhatsApp version should work for your Samsung Galaxy Note 4. Are you experiencing any problems?

Uninstall the app, restart phone, then install it again. Let me know if that works. 

Looks like it's time for a battery replacement. Was the phone like this before or do you notice deteriorating performance in battery life? 

That was supposed to say a lasting 45 minutes not asking 45 minutes. Using voice text, sometimes it's annoying.

1. Tap Phone > Keypad tab.
2. Tap More options > Settings.
3. Tap Call > Voice over LTE settings.
4. Tap Use VoLTE when available / Do not use VoLTE.

Let me know if that works for you.

Hi there. Did you do anything like change settings or install any app before this started happening?

Open Settings -> General -> Language & input -> Languages -> English.

In which language is your phone right? I can help you by translating it to that language so you can navigate thru your phone easier.

Did you make any changes on your phone lately? Maybe a new home launcher app?

Hi there. Did it die while going on the update? Or did it die after finishing the update?

Are you sure they are completely download? Use a file manager and check for the downloaded files. Usually you can find them in a folder named "Downloads".

Hi China. It's Smart stay. Your phone uses front camera to determine if you are looking at the screen.
