Universal Magnetic Phone Holder

My wife purchased this Andobil Heavy Duty cell phone holder for thick cellphone cases for me after I was forced to return my Raxfly cellphone holder after it kept automatically releasing my cell phone and lettting it fall to the car floor. So we tested the Andobil with my wife’s Cellphone as it has a thicker battery cellphone case. We drove 140 miles and it was held securely. I thought this is finally the answer! Nope! It was made to handle thick cellphone cases, but not REALLY thick cellphone cases like my WIRELESS battery cellphone case (see the pic). We tried my phone in the holder on a short 7 mile drive and it worked loose twice and would have fallen had I not caught it. I thought here I go again, I gotta return it! But then I thought, I’m probably not going to find one that is much better! Then I had an epiphany! Why not modify it and MAKE it better?! Now the Andobil had two basic problems. Although the side grabbers were nearly as high as my phone case was thick, the foam sides were to too smooth to grab and hold the phone securely. Secondly, the grabbers did not curve over the top of my phone cases’ side, so the phone could fall forward and out. I thought why not make the sides grabbers curve over the sides of the phone case. So I found a scrap piece of 3/4” diameter grey plastic electrical conduit, cut of a 1” section and sawed 3 pieces lengthwise which gave me 3 crescent shaped sections. I took two of those sections, sanded and rounded the corners, and scuffed the surfaces for better adhesion of glue and paint. I then glued each crescent shaped piece to a grabber with a 1/8” overlap and glued them with JB Weld J-B Kwik two part epoxy (see the pics) and let setup for a little over an hour. I then painted each crescent shaped piece with black paint and then added 1/2 of of small tubular weather striping (1/8” wide) and and 1” long beneath each crescent where it would curve over the phone case an act as a soft cushion. I glued them in place with rubber cement and covered them with black liquid electrical tape to further secure them in place, match the phone holder color and increase the holding power. I then installed it in my car and let the J-B Kwik and liquid electrical tape harden over night. Wel, the proof is in the holding! I put my thickly cased cellphone in the holder, went on a 24 mile drive over winding, hilly roads and over speed bumps at 25 miles an hour ...the phone never budged! Simple mod solved the problem. Note to Andobil: this mod would not have been necessary if you had made the grabbers taller, curved at the end and covered with a non-slip cushion! It would be so simple in the manufacturing process!!!
