My new SJ7 came with 1.13 firmware and I installed v1.15 right away. I have to report two issues that I am not sure if they are bugs or features of v1.15 (since I am a newbie on this), apologies if these have been mentioned before
1) When I take a photo, the wifi comes on!
2) I have set the date format to dd/mm/yyyy but on the pictures and videos it still appears as yyyy/mm/dd
I also measured the battery's capacity. I let the camera turn off by empty battery, I turned it on again to let it turn off by battery two more times. I charged it using a 2A samsung charger and took some pics of the charging meter. The charging current is limited at 360mA, which explains why it needs 3 hours to charge. Charging stopped at exactly 3hours which means that there is probably an internal timer which stops the charging process at this time. At 2.40 hours of charging the capacity was at 870mAh while 20 minutes later barely reached the disappointing value of 880mAh. Which explains some complaints about battery life.
