Ok i am extremely new and i just joined and i come here often for situations i can relate to when it comes to my phone but this is my first time posting anything.... but for awhile now my phone has been shutting off when i take pictures with flash when i would have like at least 15-30% battery life is it normal for it to completely shutt off? ive had times where the battery would be low and the app would close but not the whole phone would shutt off... is there something wrong with it? is it even a problem or am i over thinking it? is it a battery problem or something else plz help!.
