CaptainClaw besides the issue when taking 5-10 shots and the shutter button is not responding.
That can’t be fixed because it’s a limitation of the 7s Gen 3. 5-10 shots with HDR is more like 50-100 shots (then merged to 5-10) and that is simply a lot of work for almost all chips on the market. These are the stats for the chip:

97/12.5=7.7 images per second, which is about right. Because once you pass 8-9 the chip can’t process them fast enough. Shoot rapidly without HDR if you want no “not responding”.
