I realize this may have no validity on a forum dedicated to computers but it's worth a shot.
Since this Tuesday (February, 19th) my phone has been acting weird. I realize it has been one day but the run down has been quick.
On Tuesday I left my phone at home in the morning at 7:00. I believe it ran out of batteries and died although I could be wrong. Once I got home at 5:00 I searched my pants pocket to call my mother to let her know I was home. I discovered it was off and did not panic. Upon turning it on I noticed the interface was rather sluggish. After calling I turned it off and back on and it worked fairly well.
Well today, Wednesday (February, 20th), I picked the phone up and expected to use it for the music capability only to have it say
"MUSIC PLAYER INITIALIZING. TRY AGAIN LATER."
I guessed I might as well try again later and trudged off to the bus (7:00). Later (Around 11:00) I tried and got the same message. I turned my phone off and on, this is where things get glitchy. It was stuck in a boot screen loop. Not the actual turning on, but the boot into the interface.
I decided it was just funky and put it away. I got home (5:00) and try to use it to find it reacting VERY sluggishly, taking upwards of 30 seconds to recognize one command. I close the phone to cancel all commands so as to not overload. Once closed I get the novel idea of using the exterior method of opening the music player, I hold down the center button. It stays on the clock that shows up when closed. I open it and the clock stays on the screen whereas it should change. I turn the phone off and wait about 10 seconds before powering it back up. Upon turning on it is stuck in a turn on turn off loop. During the On phase an error message appeared, Error Log and something with Flash, I neglected to write the message down in absence of mind. I flipped the phone over removed the battery and waited a meager 15 seconds before replacing it and restarting the phone only to have the loop return without the error message.
It turns on for about 1 second then turns off for about a second. I would say the on/off times are parallel. My Phone is the Samsung Juke, nothing too special about it.
