Flygrip can be installed directly onto most phones. Below are some cosmetic and design issues that sometimes cause a problem, but for those phones, and easy fix it to use your phone with a case, and have the Flygrip installed directly on the case. We have found that this solution works for everyone.
Only two phones that we have found that do not allow direct adhesion with Flygrip. The two phones are Iphone 4S and Nexus 4. Both of these phones are built with Gorilla Glass on the back, and nothing sticks to Gorilla Glass. For these two phones, you should use one of our cases and mount Flygrip to the case.
Phones with built-in kickstands
FlyGrip can be used when you apply FlyGrip directly to the back of a phone with a built-in kickstand (for example the HTC Thunderbolt and EVO 4G). FlyGrip can not be used on a case of a phone with a built-in kickstand, as the built-in kickstand will be covered and can not be used. The advantage of FlyGrip's kickstand is that it will provide both portrait and landscape positions over HTC's strictly landscape option.
If your phone has a built-in kickstand positioned towards the top half of the phone, for example the Microsoft HD7, you will be able to use FlyGrip when applied on a case or directly on the phone.
Phones with a little 'chin' on the bottom back
Phones like the Motorola Droid have a little "chin' on the bottom back. FlyGrip should be placed right above that area, as FlyGrip needs to be applied onto a flat area of the back of the phone to remain firmly in place.
Phones with "split" battery covers
Some phones (for example the Droid) have a back cover that hinges right where FlyGrip needs to be attached. FlyGrip works best if applied to a case. If you want to use FlyGrip on such a phone without a case, there is no easy way to open the battery door, as FlyGrip needs to be installed over the battery case.
Remember, Flygrip offers a satisfaction guarantee, so if you find that for some reason your phone does not work well with Flygrip, you can return for a full refund.
There are SO MANY case manufacturers in the market, and each case manufacturer has a variety of case types for each phone model, so it is difficult to keep up with which case will work with Flygrip's adhesive.
There are some things that we know for sure.
Most cases will work with Flygrip. Materials that are known to work are hard plastic cases, TPU cases, Aluminum cases, and wood cases.
Cases that have a rubber material, like Otterbox cases, will require the use our special primer. This primer gives added adhesion to materials that are difficult to stick to. We can include this with your order if you let us know in advance that you are planning to use Flygrip with one of these rubber cases.
The jelly silicone cases will NOT allow the adhesive to bond. If you have your heart set on using one of these cases, the only way around it would be to cut a section of the back of the case and have the Flygrip mounted to the back of your phone (We have a video that shows this on Youtube). We would hope that you would just use our complimentary case at this point, since it will provide just as much protection as the silicone cases.
