Indeed it is, and did report this before but had no photos to back up my claim!

looking forward to the next release as there seems to be quite a few bugs reported by people

left the t deck a few days reset it with a fresh install of 0.9.11 and within 6 hours and 40 favourited contacts they all went corrupt again! exactly the same as in the pictures. so have fully reset the application again and my switch on auto add of repeaters only without favouriting ? just trying different things but find it super weird

Improved in v0.9.12

  • GUI: contacts could become garbled/corrupted after malformed contact updates or persisted non-terminated names
    • Contact update command parsing now enforces the full minimum frame length before decoding, rejecting truncated payloads instead of ingesting garbage bytes
    • Contact names loaded from frames and storage are now explicitly null-terminated to prevent string overrun into adjacent contact fields
    • Discovered-contact cache updates now use bounded copy for names, preventing overflow that could corrupt contact row state and right-side badges/actions
    • Persisted contact route lengths are sanitized on load so invalid values no longer destabilize contact rendering/state

And what actually does the TEL badge mean?, when is it supposed to make sense?
