Is find my iPhone 100% accurate?

So I have been tracking my girlfriend for a few weeks because I'm suspicious of a guy she has been traveling to work with. Twice I have asked her where she has been and the dot has been around 500 meters off of where she said she had been. Instead of being in a house it has shown her in a park 500 meters away? Could this be a glitch in app? Or maybe GPS failure?

IPhone 4 speaker not working? - 1

Today a little bit of water got on my phone. My waterproof case broke and I had it in water and it wasn't anywhere close to being completely submerged.everything worked fine, my phone was just a little wet. The liquid indicator in the headphone jack was activated, though. Also everything works fine except sometimes when I try to listen to music the speakers won't work. Also the volume buttons won't work. If I double click the home button and slide to the left to the volume controls, it doesn't always show up. When I try to adjust the volume with the buttons on the side of the phone it doesn't work. It's been on and off working since I got it wet. It works fine with headphones. Is there anything I can do? It works on and off.

Iphone 4s volume not working? - 1

So I splashed a little water on my phone at the pool today but it was a very small amount and I thought it only got on the screen. I wiped it off quickly too. But now, the volume isn't working and the volume icon shows up but the bar doesn't change. The volume only works for phone calls and I can adjust it then, but the volume doesn't work (its probably off)/ is non adjustable for everything else (music, youtube, saved videos). I already reset my phone and turned it off, it doesn't help. What do I do, can this be fixed? I'm so worried.

What's a reasonable time for a teenager to turn off their electronics?

I'm 16 years old, and i love and respect my parents very much.recently, they have been cracking down on the use of electronics and making 10 o'clock the shut off time for all electronics. For some reason, this hasn't been brought up until about a week ago. And was really enforced about 2 days ago. For me, the rule seems harsh, considering i'm a night owl that stays up until 1 or 2 in the morning, AND the only way i can trick my body into sleeping is listening to music.eventually yes, i could brake the habit, but that isn't the point. So i'm asking other parents, or teenagers when an appropriate time would be, if any.No, i don't stay up and text, no i don't do anything that would raise suspicion, i literally use the music on my iPhone and read a book.

Silicone (soft) vs hard plastic iPhone case?

Will the silicone or hard plastics iPhone cases protect the phone more from dropping it?

Also, do life proof life cases really work well for dropping your phone or getting it wet?
