While on "Lens List" tab, touch and hold-down (long press) on a lens till pop-up menu shows up.
There are several options such as "I Have One" and "Add to Wishlist". Click it and the lens will be added to the list and brings you to the corresponding tab. When you want to go back to "Lens List", you can either click the "Lens List" tab or BACK button.

Dr. EFLenses APP: Bug Collector

If you got any problems while using this App regarding stability of the software it-self, please email me or leave a comment down below. Although the goggle play has a mechanism to report crash report, however, sometime these information does not sufficient to determine the cause of a bug.

Currently there is one bug that I have trouble identifying it, which is causing the app to crash while doing lens comparison. If you encounter this problem, please provide your android version, which lens are you reading, and a short description the situation.
