The first-generation Pebble (now dubbed Pebble Classic) is, in my opinion, the best smartwatch in terms of cost/benefit. Unfortunately, a few of them start to manifest screen tearing after a few months of use, and mine was one of the “lucky” ones:
At first I thought it was a software issue, but the actual cause is that the screen connector does not cope well with the frequent vibration alerts. Such connectors are usually hard to fix/replace, but the gentleman on the video below realized that some pressure over the connector solved the issue. His ingenious choice of padding material caught my eye: small pieces of toilet paper!
