So I just barely went for a flight everything was normal then about 5 min in I got a low voltage warning then it said landing what does that mean and what do I do?

Did you start flying with a freshly charged battery?

The phantom has built in safety features to try and prevent a crash. In this case there  was some problem (I assume) which resulted in the low voltage error. When low voltage or critically low battery events occur,  the fail safe feature kicks in and auto landing happens to try and prevent it from falling from the sky.  Can you share more info about the flight? Was your battery fully charged before you flew? Have logs?

And please, read the manual!!!! You need to know this stuff BEFORE you fly! It will save you loads of issues!

Hello, did you use a fully charged battery and warm it up before flight? When you see that the drone is landing, it is recommended to use the sticks to move the drone to a safety place in order to avoid the obstacles.

The battery was at about 80% I flew it erlier that day to get a quick picture. I let the drone warm up before and everything went good for a normal take off and flight I safely landed it.

I've had this from flying on 50% battery from cold using too much throttle.  The battery needs to be either fully charged or warm in my experience.
