OnePlus has only recently announced the OnePlus 2 but the company hasn't stopped there for this year, confirming the OnePlus X at an event in London on 29 October. There will be two versions of the new OnePlus handset, one that's finished in black glass called Oynx, the other that's a limited edition ceramic. There will only be 10,000 of the ceramic models made.

The OnePlus X measures 140 x 69 x 6.9mm and comes with a three-position notification slider on the side, so you can switch between silent, priority and all notifications easily. Internally, there's a quad-core Qualcomm Snapdragon 801 chipset, with Adreno 330 graphics, and 3GB of RAM.

It comes with a 5-inch Full HD AMOLED display for a pixel density of 441ppi so it is smaller than the other two OnePlus smartphones available. A non-removable 2525mAh battery is on board and the OnePlus X also offers microSD support in a combined storage or second SIM slot. That means that those who want a dual SIM arrangement can have it.

Additionally, there's a 13-megapixel camera on the rear of the OnePlus X, offering a f/2.2 aperture and boasting a 0.2-second autofocus time. OnePlus says this will be the fast camera it has offered so far, thanks to phase-detection AF. There will also be an 8-megapixel camera on the front. 

The OnePlus X Onyx will cost £199 and will be available from 5 November. It will be available through oneplus.net and you'll need an invite to buy it. The OnePlus X Ceramic will cost £269 and will be available from 24 November.

BlackBerry has confirmed it is working on an Android handset that will be called Priv and pre-orders have begun already through Carphone Warehouse.

Official photos released by BlackBerry show the Priv features an integrated keyboard within a slider mechanism at the bottom of the device. There is also a visible speaker grille that stretches across the entire width below the keyboard. A Micro-USB port sits central and a headphone socket is on the far left next to the charging port. 

There are three buttons on the right-hand side of the device, with the larger buttons working as volume rockers, while the centre smaller button is what is used for activating the notification centre. Another singular button is on the left-hand side, which looks to be the power button. The rear camera is central and the pictures show it coming with a dual-tone LED flash - something also confirmed in the official specifications.

The BlackBerry Priv features a 5.4-inch AMOLED display with curved edges, and it has a Quad HD resolution of 2560 x 1440 pixels. It is powered by a 1.8GHz 64-bit hexa-core Qualcomm Snapdragon 808 processor, supported by 3GB RAM, 32GB of storage and a microSD slot. You'll also find a 3410mAh battery with an 18-megapixel rear camera and a 5-megapixel front-facing snapper.

The BlackBerry Priv will run Android 5.1.1 Lollipop with a skin over the top and BlackBerry software will be present through apps. Shipping is expected on 6 November and pricing sits at £579.99 SIM-free.

HTC has just announced the One A9. It runs Google's latest version of Android 6.0 Marshmallow, features HTC's Zoe camera mode, and looks a lot like the iPhone 6S. It has an all-metal body, 7.26mm-slim profile, curved edges, and a glass screen, for instance. There's also a new fingerprint sensor for Android Pay support located under the home button as well as a bottom-mounted headphones port. It's basically an Android iPhone.

The One A9 also features 5-inch 1080p AMOLED screen, Qualcomm's new mid-range Snapdragon 617 processor, 16GB or 32GB of storage with a microSD card slot, and a 13-megapixel camera. The HTC One A9 will even be among the first smartphones to sport Now on Tap and other Marshmallow features.

In our hands-on review, we said the most striking thing about the HTC One A9 is how it feels in the hand. It's a lovely handset. The size is good and the build quality is excellent. But there's a lot we still need to examine in detail, like the performance of the battery, how that new software sits on Marshmallow and critically, how the new camera performs, etc. The final piece of the puzzle is price: the HTC One A9 will be £429.99 SIM free in the UK.

A SIM-unlocked version in the US will feature 3GB of RAM and 32GB of storage for $399.99. It comes with an unlockable bootloader that doesn't void the warranty and gets updates straight from HTC. Along with that, you will get six free months of unlimited Google Play Music and HTC's Uh Oh Protection.

Pocket-lintSamsung Galaxy S6 edge Plus-15

Moving into what phones to look forward to in 2016 and you'll find rumours for the Samsung Galaxy S7. The device has been codenamed Project Lucky and two models are expected, referred to as Hero and Hero2.

The current leaks suggest that you can expect a 5.2-inch device and a 5.8-inch device, but there have also been reports of a 5.7-inch device with a Quad HD display.

There have also been reports of 3GB of RAM and 4GB of RAM, as well as a 16-megapixel rear camera and a 5-megapixel front camera.

The LG V10 was announced at an event in New York on 1 October and it marks the first Android phone in a new line of "V" smartphones that the South Korean company is currently planning.

CNBetaSony compact premium

While it wasn't announced with its Xperia Z5 siblings at IFA, there has been some speculation suggesting that Sony will also be releasing a Xperia Z5 Compact Premium in Japan.

It is rumoured to feature a 4.6-inch display with a Full HD resolution, which would already be a step up from the current Xperia Z5 Compact, and 4GB of RAM has also been suggested. A 23-megapixel rear snapper, 5-megapixel front snapper, 2900mAh battery and Snapdragon 810 processor are also claimed.

CNBeta said the device would be available in October, but provided no details on pricing. The accompanying promotional image suggests it will be exclusive to Japanese carrier DoCoMo however. We will update this feature if Sony announces anything official.

NextbitRobin - HeroShot - 1000x1000

Nextbit announced its first smartphone at IFA 2015 - the Nextbit Robin - described as a cloud-first Android device. The Nextbit Robin wants to shake up both hardware and software, taking Android deeper into the cloud with a unique storage management approach.

The unique selling point of the Nextbit Robin is how it manages storage. The device comes with 32GB of internal storage, but has 100GB of cloud storage too. It works seamlessly with the cloud using that space to backup and offload the content of your phone and this doesn't just include photos and videos, but apps and data too.

Nextbit will sync your apps with the cloud, meaning it can free-up local storage as it's needed. That means you won't run out of storage when you need it, for example taking photos or video on a day out. It does this by backing up to the cloud at convenient points - at night when connected to Wi-Fi and a charger, for example.

The software recognises the apps you use regularly, so keeps them on the device, but, for example, if you rarely use a travel app, it will let that space be over-written with other data. The real magic is that when you want that app back again, it can be seamlessly restored to your device with all the data in place, and no need to login again.

The Nextbit Robin is on Kickstarter to help demand planning but it will hit general retail in Q1 2016, for $399 (£260) and will be available internationally.

AcerAcer Predator 6

Acer announced the Predator 6, a high-end smartphone aimed at gamers, during its pre-IFA press conference. The device has a 6-inch screen and deca-core MediaTek processor - that's 10-cores of power - and there is 4GB of RAM in order to play console-style games when on the move.

There's a 21-megapixel camera on the rear, four speakers and haptic feedback when held in portrait mode to help simulate joypad controls on the touchscreen. The Acer spokesperson on stage said it would "dominate any mobile games you can throw at it".

Few other details have been released about the phone so far, but it joins a whole family of gaming products from Acer, all of which come under the Predator banner. A Predator 8 tablet was announced earlier this year and the high-end smartphone has much of the same functionality. We will keep you updated.

Sony launched not just one but three flagship smartphones at IFA in Berlin - the Xperia Z5 Compact, Xperia Z5 and the Xperia Z5 Premium. All three stick with the tried and tested OmniBalance design and waterproofed bodies, but Sony has added a fingerprint sensor to the signature side power button on all three models.

The Z5 Premium comes with a 5.5-inch display, while the Z5 sticks with 5.2-inches and the Z5 Compact has a 4.6-inch offering. The resolutions all differ too, with the Z5 Premium featuring the world's first 4K display on a smartphone for a whopping 806ppi, while the Z5 sticks with 1080p like the Xperia Z3+ and the Z5 Compact keeps with 720p.

In terms of other specs, they all come with an improved camera. The Z5 family feature a 23-megapixel rear snapper with a super fast autofocus of 0.03 seconds and a 5-megapixel front snapper. The Xperia Z5 Premium is the most exciting of the three, featuring a very excessive mirror finish, alongside black and gold options. It will launch in November, while the other two are already available.

Created by Motorola, and now shifted over to Google after the sale of Motorola to Lenovo, Project Ara has recently announced that it's postponing and won't be expected until 2016.

Project Ara is essentially an exoskeleton that allows users to modify what parts they want. That way someone that wants to spend the bulk of their budget on the camera, but doesn't need as much storage, can chose to upgrade that way. Perhaps one person will skip NFC in favour of faster 802.11ac Wi-Fi, for example.

There should also be third party components on offer that will allow for competitive pricing as well as new types of parts - like sensors. A person with diabetes may want a blood sugar sensor where another may not.
