Ive been trying to get ahold of blackview and tiny deals where i got the phone... it wont charge, ive tried everything they told me to do and it still wont charge when you plug it in.... super frustrating and its hard to get ahold of a real person to talk about the issue... I wanna ship it back and get a new one under warrenty but so far nothing has happened.....

ok this is for anyone else having this issue with charging and /or no sound coming in from the mic as well.
you'll need a small hex and phillips head screwdriver and tweezers. I bought a whole set from hardware store for $8.
undo the outer screws on side first, then back and gently lift open, use phillips then to remove cable attached to backing(2 scews)
next unclip battery and remove.
NOW...Under the battery is a flat cable that runs from the bottom board where the charger is, to the main board and clips in both ends.
this is where the issue is! any bump or drop causes the cable to slip out of these little flat clips so gently push the cable into the clips and fold the clip lid down , you'll see a line which is as far as you need to insert. then to make sure it wont happen over and over, get some tape and tape that clip down to the cable and housing if needed , carefull not to interfere with any other components.
put back together and should be all good!
Ive had to do this 3 or 4 times after its been dropped but now have taped it well into place so fingers crossed.
and I'm no expert. there is a tutorial on youtube on how to dissasemble so follow that if needed but honestly it doesnt take long like 20min.
definitely a design fault
hope it helps
