## Description

Caterpillar CAT S31 Dual-SIM 16GB Rugged IP68 Factory Unlocked 4G/LTE Smartphone (Black) - UK/EU Version

Review: Wie gewohnt - Nicht mein erstes CAT und da beim Vorgänger nach 5 Jahren die Ladebuchse wohl einen Wackelkontakt hatte, so daß man beim Laden immer etwas tricksen musste, habe ich mich dann doch entschlossen dem S30 ein S31 folgen zu lassen. Der Preis des Verkäufers war gut, Versand etc. einwandfrei. Ich habe keine Probleme mit dem Telefon, weder mit Bluethoot noch mit den im Gegensatz zum Vorgänger deutlich herausstehenden seitlichen Tasten was von einigen Benutzern immer mal bemängelt wird. Das einzig nervige ist der ständig präsente Google und Tcom Schrott aber das betrifft grundsätzlich alle Mobile Phones
Review: 安心のイギリスメーカー製品 - 追記 2019/6/21 OS 8.1にアップしました。 外部SDは128ギガを認識しますし同梱の説明書にもそのとおりの記載があります。 説明写真と異なりストラップホールが無いのでalumania STRAP TYPE HEADPHONE CAP for 3.5mm PLUG (ブラック)を購入してしようしています。イヤホンジャックのキャップは切り取りました。キャップにはシールドが無いので単にホコリ対策と思いますが、上記製品をガシガシにねじ込んでおけば防水性に問題はなさそうです。 また、中華タフネススマホに良く見られる深いusb、イヤホンジャックではなく、国内の普通の規格なので安心です。 何よりも信頼の重機メーカーCATのロゴが光っています。 またスピーカーも前面に配置されているので実用的、4000mAhのバッテリー、前面物理ボタンのタッチ感が良く、側面には余計なSOSボタンも有りません。
