...regarding last two beta’s

everything seems okay thus far with beta 2... one thing ive noticed with last 2-3 beta’s is my bluetooth turns ON all by itself...! i always leave/have bluetooth off (jus dont use any devices), but a few beta’s ago...i noticed first thing every morning...bluetooth is ON! first i thought it was from plugging it in to charge every night, then at full charge, it was bumping it on.... last few nights, i haven’t been charging over night...an stillll noticed last 3 mornings i grab phone an bluetooth is ON again! so, in conclusion...the onlything i can come up with; something happens or runs during un-use, during the night, every night...thats tripping bluetooth on (on its own)... i checked the last two nights an phone had done an icloud backup around 3am, both nights! so, after backing up to icloud...is this whats turning on my bluetooth!?!?!? if not, its some other system process (background prehaps) that occurs EVERY single night...! thought i’d share problem and/or see if anyone else is experiencing same issue...
