Yeah, I know, but my problem is modern phones lifespan which is usually 2 years, when the battery starts to deplete very fast and overall performance starts to fall. I'm a long-time player (for almost 5 years) and changed 3 phones during this period due to different reasons but the fact is, that I had to start the game from the very beginning every time I bought new phone. Many games gets updated every 3-4 month and it's quite easy to catch on the progress, but in your case...to my estimates, I'm almost 60 updates behind from where I first started one day.
If the integration is not possible, I'll understand. But if you can, I believe that many of your fans (not only me) would appreciate this addition.
P.S. You can implement gallery unlocking code as an alternative
