To start off my original 8800 that I had when it first came out was working perfectly as my main MP3 player. I am not a big fan of carrying multiple devices and having 2GB of music is more than enough for the travel time I incur on a daily basis anyway. When using the media player, I was able to switch applications as normal and also lock the device and still use the pause function without issue when locked. I really never needed to manually flip songs as I use the shuffle mode quite a bit anyways. I was running OS 184.108.40.206 after before upgrading from 220.127.116.11 I think. Still my functionality remained the same and was happy.
Unfortunately, wear and tear on the audio jack took its toll and I had no choice but to replace the 8800 with another 8800 as my travelling time was getting to be unpleasant without my tunes of relaxation (mostly industrial, jazz, pop, rock). So now I have my new 8800 and upgraded to the latest OS from Telekomsel with no problems and restored my BB settings without a hitch and all the 3rd party applications functioned as normally. I tried to use the media player and place the BB in the usual lock mode and to my amazement, the BB completely killed the media player and reset the settings so now I can't resume where I had paused if I needed or resume where the music had stopped. I tried this with manual locking and auto locking and in both cases.
At one point I thought it would be the theme but no matter what theme or what application is in the foreground, locking will kill the media player. So in a effort to get back my feature I downgraded to the same OS as my previous BB and still no luck. I don't have my old BB anymore, although I should have kept it but warranty wouldn't allow me to do that. So I don't know if there was some sort of bug or a feature that worked somehow.
If it is a bug, I want my bug back and my security also!!
