Review: Llevo poco más d 2 meses con el teléfono y ya me empezó a dar problemas con la bocina. Se corta la voz cuando habla. También en cuanto le puse algunas aplicaciones se empezó a poner lento. El teléfono tiene precio bajo pero si quieres algo de mejor calidad tienes que comprar uno más caro

Title: Not what I was really looking for.
Review: The 8g RAM was misleading. I missed the 4 + 4 RAM split. Phone is too slow for my needs.

Review: Hab das Ulefone Note 21 als Zweithandy geholt und bin echt zufrieden. Läuft flüssig dank 8GB RAM + Octa-Core, und mit 128GB Speicher hat man genug Platz. Das Display ist richtig gut – flüssig, farbenfroh und macht echt Spaß.Akku hält mal locker 1-2 Tage durch. Kamera macht bei gutem Licht ordentliche Bilder, nachts wird’s schwieriger. Einziger Minuspunkt: Lautsprecher könnte lauter sein, aber mit Kopfhörern kein Problem.Fazit: Für den Preis echt top – läuft stabil, Akku hält lange, und das Display ist überragend!

Review: Ich habe das Handy für meinen Sohn bestellt. Es sollte sein erstes Handy sein. Bin von dem Handy sehr überzeugt. Die Verarbeitung ist top. Die Bildschirmauflösung ist auch sehr gut. Die Farbe schwarz mit dem Effekt auf der Rückseite sieht sehr hochwertig aus. Kann das Handy nur jedem empfehlen. Super 👍🏼
