5.0 out of 5 stars This phone is fast!
Reviewed in the United States on August 19, 2018

I changed carriers and decided to go outside the box and get a one plus 6 and holy inbred Nascar fans thing is fast. Coming from an iPhone X to this is a massive upgrade on most terms. And it's half the price. Yeah it don't have wireless charging but who cares. It's dash charging (which actually comes in the box) is stupid fast. Like sit a fat kid at a table and the cake right in front of him fast. The cake has no chance and neither does the loading times. There is no hang ups unlike your ex lover. If you want speed like a white guy on meth this is the phone for you. If you want beautiful display like a sexy dressed up mannequin in Victoria`s secret, this phone is for you.

5.0 out of 5 stars One of the best phones in the market
Reviewed in the United States on January 8, 2019

Great phone for the price and works very well multitasking and switching applications when needed. It does it in a breeze and faster then iPhones as I've been watching some review on it online. Those reviews included speed tests of all sorts. Downside would probably be the speakers but that's pretty much it. It only has the bottom speakers. It's not a necessity but it's nice to have some stereo speakers. Overall one of the best phones out on the market without a doubt

Was a little worried to get the incorrect model based on some of the other reviews. I received the A6003 model. This phone is by far the coolest purchase i've ever made for myself. I simply can't slow it down - its always blazing fast. I've been using it for a few months now and it's just as fast as new. Doesn't get hot when playing PUBG on max detail settings and no lag. The screen is very nice to look at. Also...battery life! It seems like it lasts forever. When its time to charge, the dash charging is incredibly fast.

4.0 out of 5 stars I received the A6000 not the A6003
Reviewed in the United States on October 31, 2018
Verified Purchase
While this is not the exact product I ordered thankfully it doesn't matter because I would incur a loss by returning it. If you plan on using this device in the US that may be a different story. The item was shipped in a soft envelop/bubble wrap style package resulting in the box corners being slightly squished in, the phone, however, was in excellent condition and works as expected. Oneplus devices are larger that what I am used to but I have gotten used to it. The phone is quite grippy if cleaned of fingerprints and used with recently washed hands, however, it gets extremely slippery after accumulating fingerprints. I would recommend a case. The case provided with the device was quite adequate form my use so I would advise trying it out before purchasing one separately. Cheers.

The 1+6 dual sim is worth its value. It's fast easy to use. The dual sim is an added advantage. Camera photos and videos are of very high quality with clear sound. I think it's even better than iphones for its value.

5.0 out of 5 stars Best Phone I Have Owned
Reviewed in Canada on October 6, 2018
Verified Purchase
I purchased this phone recently and I have to say this is by far the best smartphone I have ever owned. It is insanely fast and very stylish. The phone itself is quite slim which is impressive for the specs it carries. The phone comes with a screen protector right out of the box and includes a case as well. I recommend buying a 3rd party case for better quality and comfort though. Overall this phone is amazing and I would recommend it to anybody and everybody.

WARNING: This model is actually the A6000, not the A6003 like the page advertises.

Très bon smartphone c'est avec lui que j'ai découvert la marque.
Tout simplement un des meilleur rapport qualité-prix à l'époque. Rapide pratique sans aucun souci de fonctionnement , la reconnaissance faciale est un pur bonheur.
L'appareil photo est très bien le logiciel du téléphone et tout simplement unndes meilleurs du marché la surcouche Oneplus est excellente.
La meilleure navigation par geste que j'ai connu
Un super téléphone avec une excellente autonomie qui couplé à la recharge rapide permet de ne jamais tomber en panne de batterie.
J'ai retrouvé les choses que je recherche dans un smartphone.Pour resumer
Autonomie , performance, photos et tout ça pour un prix plus que correct
Pour ceux qui ne sont pas très encoches elle se fait vite oublié et peut être carrément masqué
En plus OnePlus est particulièrement réactif sur les mises à jour ce qui est un point important aussi.
Je recommande sans hésiter

5.0 out of 5 stars TOP in tutto, anche se...
Reviewed in Italy on October 8, 2019
Verified Purchase
Come da titolo, l'ho comprato perché volevo certamente fare un salto di qualità rispetto al mio precedente Huawey p10 lite. Ed in effetti è stato così, decisamente: velocità del processore super, memoria da 6GB che permette di dormire sonni tranquilli, esperienza d'uso quotidiano molto buona, tenendo conto che lo smartphone lo utilizzo per fare tutto, agenda, social, navigatore, foto, video, gioco, etc, insomma, un uso davvero intensivo. Certo, qualche problemino l'ho trovato e sotto nel confronto tra PRO e CONTRO li descrivo nel dettaglio:

PRO:
1) Velocità
2) Non lagga MAI
3) Mai nessun problema con nessuna APP (ne utilizzo in tutto una 50ina)
4) Ricarica super rapida (da 10% a 70% in 30 minuti!)
5) Schermo luminoso e ben equilibrato
6) Tasto laterale per modificare da SUONERIA-VIBRAZIONE-SILENZIOSO (UTILISSIMO!!)
7) Batteria buona ma non super (ci faccio 1 giornata di uso intensivo e arrivo a sera al 25-30%)
8) Buon vivavoce
9) Led di notifica ben luminoso (per me utilissimo!)
10) Buonissima ricezione, volume e chiarezza delle conversaioni

CONTRO:
1) la fotocamera, seppur buona, mi ha lasciato un po’ perplesso. Complessivamente non l'ho trovata meglio di quella del p10 lite, ma quello che più mi ha infastidito è l'effetto Boken che, nei selfie, fa sembrare una foto alle Maldive come una fatta a Riccione (estremizzo, ma per far capire il concetto). Vabbè, provando altre decine di APP di foto ho fortunatamente trovato un'APP (YouCAM Perfect) che ne limita un po’ l'effetto, rendendo l'esperienza d'uso più adatta ai miei canoni.
2) Non esiste un "Seleziona tutto" nella galleria, cosa che ho sempre trovato utile per pulire in un sol colpo, ad esempio, tutte le foto di Wapp. Vabbè, utilizzato anche qui un'APP terza
3) HOTSPOT: nota dolente. Normalmente, non avendo connessione via cavo a casa, utilizzo da sempre lo smartphone in tethering avendo un abbonamento con decine di giga. Ecco, inspiegabilmente, una volta connesso, randomicamente, questo disconnette la connessione. Già verificato tutte le impostazioni e cambiato PC, ma il problema è proprio dello smartphone. Vabbè, me lo tengo così

Detto ciò, sono comunque complessivamente soddisfatto, anche se sarei stato più felice senza i problemi sopra elencati. Quindi, ne è valsa la pena spendere quasi 450€? La risposta è SI

5.0 out of 5 stars Very nice phone
Reviewed in the United Kingdom on October 3, 2018
Verified Purchase
Pros:
Fast and responsive.
Good battery life (2.5 days moderate use).
Charges pretty quickly.
Duel sim is very handy when you live in such a rubbish area for reception as I do.
Fingerprint sensor is very quick and nicely positioned.
Screen is a nice size.
Works fine for voice calls.
No problems with signal dropouts.
Manufacturer is releasing latest Android version to this phone so it will be supported for a while and seems to have good customer service.
Cons:
Came with American and Euro charger but not UK one.
Doesn't always display signal strength correctly.
No SD card slot.
Camera isn't great, only adequate.

Overall this is the best phone I have ever owned and would highly recommend it. You will need to get a charger for UK though.
