My SJ7 is heating very badly while recording. Cant hold camera if used for more than 1 hr. I am recording at 1080p 60 fps with gyro on and using Samsung evo plus U3 64 GB card which has 60 MB/s write speed. Due to this issue my battery has swollen and stuck in camera. when I try to pull it its attached string got broke. so I removed battery by metal clip, now I dont want to put it back as it may explode due to excess heating. I bought it on ebay india from reseller but dont want to send him camera to get warranty as I had bad experience before with ebay. Is there anything I can do.
