I tried to take several videos last night of a band but each time I went to save clips of 4 mins in length to my internal storage, the phone would display flashing bars as though saving but wouldn't save (just showed the flashing bars as though trying to save) and instead lock up. I had to restart each time and consequently lost my videos. I tried various recording modes and had the same issues. I was able to take and save pictures with no issues. Does anyone have a possible solution to this problem?
