### 1/5 — Ok, mit Verbesserungsmöglichkeiten

*2025-01-15*

Die App funktioniert grundsätzlich recht zuverlässig. Leider wurden aber offensichtlich einige Funktionen nicht richtig implementiert. Das Mikrofon nutzt keine Filterung der Umgebungsgeräusche, der Gesprächspartner hört quasi jedes noch so leise Geräusch um einen rum. Zudem wird das Display beim telefonieren nicht zuverlässig deaktiviert, sodass man ab und zu Gesprächspartner aus versehen in die  Warteschleife stellt.
