I recorded some videos (using the stock camcorder) and a sound recording (using the Smart Voice Recorder app) using my Samsung Galaxy S2 a couple of days ago and all of them have no sound at all when playing them back, both on the phone and after transferring them to the computer. However, I have tried recording some videos/sound recordings since then and the sound is playing fine on those (even though I didn't do anything differently to how I made the previous recordings!)! Is there any reason as to why this might have happened?? And more importantly, is there any way of getting the sound back on the previous videos/sound recordings I made?? I've had a look at other threads for those who have had a similar problem, but haven't been able to find a solution. The battery was fully charged at the time of recording and no power saving apps were running, so I can't think of any other reason as to why this might have happened! I would be grateful for any advice on this, and more importantly on the possibility of recovering the sound on my previous recordings! Thank you in advance for your help!
