Phone Holder

My user group will be smartphone users who need to use their phones often at their desks. Often, they will be doing other tasks. Most of the times, people will be holding their phones while using it, and it can cause arm pains. They need an easier way to use their phones at desks without their arms hurting.
The original product was changed so that:
It is easier to charge the phone. The phone holder with a gap to hold the cable so all the user has to do is plug the phone in and out
Cable can be attached and removed easily. I will make a little slot at the bottom for the cable to fit in.
It can support the phone without shaking. A support board will be placed on the structure to increase the stability.
