2:11 is also used in SCH-S230, SCH-V500 (but an alternative shutdown version with beats at the end) and SCH-B100 (same shutdown like SCH-V500, but the man voice saying 'Digital exciting. Anycall' in the startup sound is removed). I don't think the variant at 2:23 (the shortened variant of the sounds mentioned before in this comment used in SGH- prefix phones like SGH-E720, E330N, E900 and others) is used on SGH-M310. Only the variant at 6:02 is used. The variant at 6:02 is actually lastly used on GT-E2530 (released in June 2011)
Really useful video. It's so weird how they mixed and matched these sounds. 3 or so different sounds in a single year, sometimes old sounds on newer devices... Honestly, it gest confusing pretty quickly
Omg I can't believe you made this new video with all the Samsung Mobile (Fun Club) and Galaxy startup & shutdown sounds!!! This video includes a bit more sounds than Spiro's but maybe less than Meezytube's video. Some of the years are more correct than Spiro's video or Meezytube's video.
