hello, I have just got my brand new Xt30 III, charged up for a bit ( using my phone type c charger)
took it for a quick tour , tha camera showed me and overheating warning same thing happend at night when Iwas setting up tbe camera. Is that normal.
Also I felt that the battery felt bizarre and not very solid are all fujifilm batteries like that ?
