[Q] Power button stucked at fully pressed state

[patrez]

Hello everyone,
After three months of using my truesmart for tracking my runs, it seems that power/back button became stucked at fully pressed position.
I've tried to RMA the unit to Omate, but they told me that it isn't covered by warranty.

So basically I have to probably repair it myself.

Do you have any tips for what should I be aware of, and how to fix it?

Thanks in advance for any tips
