- La taille me faisait un peu peur mais je m'y suis très vite fait.
- Coté autonomie/recharge, lampe, vision nocturne rien à dire, les attentes sont respectées.
- Mon bouton volume up ne marche plus (défaut de fabrication ?), c'est dommage mais gérable sans problème (volume down + slide)
- Stabilisation photo/vidéo à améliorer un peu trop faible à mon goût.
Très content du rapport ensemble/prix (mon 1er rugged phone pas déçu)
Es gibt viele Erklārungen und Videos die Produkte hochleben oder vernichtende Kritiken darüber schreiben um vielleicht etwas Reichweite, Aufmerksamkeit oder einfach ein Produkt zu verkaufen.
Dagegen bich ich ein einfacher Kunde, der nur ein zuverlãssiges Smartphone gesucht hat, was auch in Notsituationen zuverlãssig funktioniert.
Das habe ich im Unihertz Tank vorgefunden.
Es ist super robust.
Hat eine wirklich starke Lampe auf der Rückseite verbaut.
Einen Großen Bildschirm.
Viele praktische Werkzeuge.
Und vor allem Dingen,die größte Ausdauer die je ein Smartphone bis heute hatte!
Im Alltag der grösste Vorteil der wirklich und effektiv zãhlt.
Das Gewicht ist auch kein Nachteil, in manchen Situationen sogar von Vorteil, nach ein paar Tagen hat man sich daran gewöhnt und will es nicht mehr missen.
Klar fehlt mir die Wãrmebildkamera Funktion, aber Unihertz arbeitet sicherlich schon daran.
Und zukünftig wird auch ein iPhone 18 oder Samsung S 28 Ultra im Alltag, dem Tank das Wasser nicht reichen können.
I would love to see another option with a speaker instead of the big flashlight and reverse charging would also be cool to have
