        Hello,

        After many testings, i saw a recurring pattern with the bug of the seemingly sporadic unability of my phone to detect any network at the boot. Strangely, my phone is unable to detect 3G, 4G, mobile network or bluethooth if i boot it when battery is less than 10%.

          How old is the battery ?
          Maybe it's time to change it.

            @stemy I commend your tenaciity! That must have taken some time to find the combination of inputs that resulted in the observed problem. Can anyone out there with the same phone confirm/deny this problem?

              @ian I've already had this issue a couple of times.
              And I think it is an FP3 specific issue. But I don't know if there is or will be any solution.

              My guess was, that the radio hardware does not get enough power to come up, or similar... 😉

                @luksus Or it is some bizare power saving mode due to low battery. I've not seen the same behaviour on Volla Phone X, Nexus 5, or the BQ Aquaris E5 (but only my VPX is still functional).

                  I'm a bit late to the party, but I can confirm this behaviour. I have a nearly brand new fp3+ (bought in late summer). Whenever I boot with less than 10% battery (e.g. because I forgot to charge it over night) it will not connect to any network. It's been very consistent and I've assumed this to be a power saving feature until now :man_shrugging:

                    I confirm this issue on my FP3+, 100% times when I boot it under 10%.
                    Additionally, it's exactly 10%, so it seems either firmware or UT software. If it were hardware, I would expect this 10% to drift over years (with the battery getting old), or being slightly different on different devices.
