The OPPO K12x 5G has already created a buzz in tech circles with its highly impressive attributes. First, it adheres to OPPO’s commitment to top-notch durability by offering military-grade endurance. And it does that without skimping in any other department. Its gorgeous design is a treat to the eyes, while its massive battery is ideal for non-stop usage. Its blazing-fast performance and high-end cameras also give users much to look forward to. One look at the device shows why OPPO has chosen ‘Live Unstoppable’ as its slogan. I got to go hands-on with the phone recently so here are my thoughts about it.
Ultra-durable design
As I’ve already mentioned, the OPPO K12x is a highly durable handset. For the clumsy ones like me, having the protection of its 360-degree Damage-Proof Armour Body is a huge deal. There’s no need to worry about damaging the handset during everyday mishaps. I deliberately dropped the phone several times to check how it fares and while I had my heart in my mouth when the phone dropped at an awkward angle one time, the phone came out unscathed from these drops.
Additionally, its Splash Touch feature makes sure that the phone works completely fine even when there are water droplets on the surface. I gave this a try by spraying some water on the display and was amazed by how flawless and responsive the touchscreen experience was.
While these were the external durability features, there’s protection on the inside too. To make sure that the phone survives drops and falls, OPPO has also given this phone’s parts sponge bionic cushioning. This means there are ample gaps between each component to reduce damage due to sudden collisions. Moreover, all the main internal components are covered with shock-absorbing foam to further safeguard them from impacts. All this is pretty impressive in itself but I was further pleased to see that OPPO has also packed an Anti-Drop Shield Case in the phone’s box. With its corner cushioning and reinforced back shell, the stylish case is claimed to offer 200% better protection to the device.
You’d be shocked to know that even without the case, the OPPO K12x 5G has received the military standard MIL-STD-810H certification. This rating isn’t easy to get, involving tests like extreme height drops (1.4m), extreme frequency drops (30 – 40 times), and 11 tons of pressure (48-seat bus running over). The phone’s design isn’t just about brawn though. It’s an absolute treat to the eyes thanks to OPPO’s signature blend of style and elegance. I found the matte finish on its rear surface to be quite attractive and the same can be said about the chic nature of its camera cluster.
There’s immense comfort in holding and using the OPPO K12x 5G. That’s all thanks to its slim profile and lightweight. In fact, at 7.68mm, it’s the slimmest phone in its segment. This makes a big difference, especially during long gaming sessions. I found no hand fatigue after long sessions of using the phone as the phone weighs just 186g. It’s safe to say that OPPO’s commitment to durability hasn’t led to any compromises when it comes to looks and ergonomics.
Battery beast
OPPO has packed a massive 5,100mAh battery inside the K12x 5G. During my time with it, I never ran out of juice in the middle of the day. I became so comfortable relying on the battery backup of this phone that I eventually stopped carrying my phone’s charger with me to the office. I’m pretty sure that those who use their phones moderately can easily extract 2 days’ worth of usage from it.
If you have any concerns about the longevity of the battery due to its fast-charging capabilities, you can push them aside as OPPO has that covered as well. The K12x 5G uses an advanced double-layer coating on its positive electrode and a triple-layer coating on its negative electrode to boost its lifespan. This leads to over four years of optimal performance, where the battery can maintain 80 percent of its original capacity despite over 1,600 charge cycles. On top of this, there’s further durability provided by OPPO’s Smart Charging feature, which adapts the charging process on the basis of your usage habits.
Stunning display
The OPPO K12x 5G’s display is also a major win. I tested it for both gaming and content streaming and can vouch for its visual quality. It’s a 6.67-inch panel that covers 89.9 percent of the front surface, thus enhancing its immersion levels to a great extent. High-end games like Call of Duty: Warzone Mobile and Genshin Impact are rendered with such clarity that I felt enthralled by their visuals during my gaming sessions. And the phone’s 120Hz refresh rate made sure that their high frame rates were rendered with utmost finesse.
The K12x 5G’s display impressed me while streaming movies and TV shows as well. It can provide 850 nits of typical brightness and 1,000 nits of peak brightness. This meant that the visuals popped with amazing contrast levels. The quality of the video was even better when using Amazon Prime Video since the display is specially certified for providing HD content on this particular app. With the Amazon HD certification, this phone is the most perfect way to watch your movies or TV shows on the aforementioned platform. On top of this, you also get Widevine L1 certification, which ensures you get the best possible video quality on the OTT platform that you’re using. If amazing video quality wasn’t enough, OPPO has ensured that we also get fantastic audio experience. With the 300% Ultra Volume mode, you can watch movies with your friends and use the speakers on this phone to get an immersive experience, even in presence of some background noise. I personally checked this feature and honestly, I haven’t picked up my earphones to watch videos on this phone since.
This phone is truly a dream for those of us who consume multimedia content everywhere we go.
High on memory
If you’re someone like me who clicks a lot of photos and videos during every outing, you’ll be pleased to know that the OPPO K12x 5G offers 128GB and 256GB UFS 2.2 storage options. Moreover, a microSD card slot is also present on the device, allowing additional expansion of up to 1TB. This kind of storage is perfect for saving all your media as well as high-end games. There’s also the super-quick multitasking support that’s enabled by up to 8GB of RAM. I found the user interface to be splendidly smooth, thanks to this. The app load times were especially impressive.
Despite ample memory on offer, OPPO has also equipped the phone with a RAM Expansion feature that can convert up to 8GB of free storage into temporary RAM. This additional RAM means a total of 16GB of RAM can be accessed on this device, which is truly insane.
Unbridled connectivity
One of OPPO’s most innovative features recently has been AI LinkBoost. This feature has made its way to the K12x 5G as well. It’s a full-link network data transmission engine that enhances connectivity to deliver a smooth and stable calling experience. I felt the difference immediately when inside a mall. The speed with which the phone switched between Wi-Fi and cellular was extremely fast and this ensured that my calls never got dropped. AI LinkBoost also helps the phone defy weak Wi-Fi signals, thus enabling faster content sharing even in crowded places like concerts and music festivals. OPPO’s AI LinkBoost quietly does wonders for this phone’s connectivity.
While this phone is already filled to the brim with amazing Android 14 features, you can rest assured that the phone will age like a fine wine as the brand has promised that it will receive two OS upgrades and three years of security updates. With these updates, the phone will feel fresh to use for years to come.
Dazzling photography
While testing the camera of the OPPO K12x 5G it was clear to me that it’s going to be a headache to its rivals. The 32MP main shooter was able to return splendid photos in well-lit as well as dimly-lit environments. Moreover, OPPO’s HDR 3.0 algorithm made sure that all my photos were worthy of uploading to social media without any editing.
In my experience, the phone’s 8MP selfie camera delivered some quality shots and captured skin tones quite efficiently. Unlike some other phones that alter skin tones to a great extent, the K12x managed to reproduce skin details with precision.
The phone’s Portrait Mode was also great to use. It creates stunning depth-of-field effects with the help of the 2MP portrait camera. This mode is so good that it will encourage you to keep clicking images against different backgrounds. And then there’s Dual-View Video. It’s the perfect tool for aspiring vloggers as it allows the capture of videos through the front and rear cameras simultaneously. You can easily give a running commentary on anything that’s being recorded, making the videos more interesting to watch.
Extra-smooth performance
At the heart of the OPPO K12x 5G is the MediaTek Dimensity 6300 SoC. While using the phone, this 6nm chip didn’t leave anything to be desired in terms of performance. Whether it was heavy tasks like editing videos and playing games or simply navigating the interface, the phone was able to render splendid overall performance. It is important to highlight that OPPO has made enough provisions to ensure that this performance lasts for years to come. That’s because the phone has been put through a 50-month fluency testing program. It guarantees that the same fluid speeds continue over the long term.
Bottom line
The OPPO K12x 5G stands out amidst the competition. Priced at just INR 12,999 it combines a sleek yet durable design with exceptional performance and battery life. For those seeking a reliable and feature-rich smartphone that doesn’t dent their wallets, the OPPO K12x 5G is the best option in its price range.
