Hi all. My Brother in law asked me to help him out with a refurbished P3S. I have a P3A and it's much different. Regardless, I noticed DJI shows firmware version 1.0.14. I can't find that anywhere. Is the bird stuck on this version? I assume I can't jump across FW versions so how can I get to the oldest one shown on this forum which is 1.2.??? Can I jump versions and if so any recommendations on where to stop, such as the 1.6 version? I'm getting a weak remote controller signal and slow feedback and hoping FW can fix it. BTW, using DJI GO 3.1.1 on a Galaxy tablet4 Any advice is appreciated.
