Hi Jes,

Thank you for your detailed and honest feedback.
We are sorry if the T5 Epaper S3 Pro fell short of your expectations. You're welcome to try the latest firmware below—it may help improve performance:

We also truly appreciate the constructive suggestions you shared regarding the T-Deck Pro.
Some of the points you mentioned are already being addressed in our ongoing development work.
Below is a point-by-point response to your ideas:

1). We are currently developing the T-Deck Pro Max model, which will come with a backlit screen and integrate both voice functionality and 4G connectivity into a single device.

2). The Pro Max will share the same case as the current Pro model. We are also looking into improving key sensitivity to prevent accidental triggers. Regarding the power switch functionality, our factory firmware includes low-power usage examples—Sleep Mode (low-power mode, consuming around 300 μA) and Shipping Mode (full power-off). We recommend using Sleep Mode to extend battery life during regular use, and Shipping Mode only when the device will not be used for an extended period.

3.) Regarding the short battery life: If you are using Meshtastic or Meshcore firmware, please note that the GPS is enabled by default, which likely contributes to higher power consumption. We will relay this feedback to the respective development communities to help optimize power efficiency in future updates.

4.) The time reset issue may also be related to the nature of e-paper displays. Since the screen uses an SPI interface, its refresh rate is inherently slower, which can affect real-time updates.

5.) Given the refresh rate limitations of e-paper screens, we are concerned that a thumb wheel—which typically requires quick visual feedback—may result in a poor user experience. What are your thoughts on this?

6.) For your reference, we do offer a PCM5102 audio version of the T-Deck Pro, which does not include 4G/GSM functionality.

Thank you again for your thoughtful input and support. We are continuously working to improve our products, and feedback like yours is incredibly helpful.
