The One UI! In my opinion, Samsung’s One UI is the best custom skin built on the Android operating system. Starting with Android 9 based One UI 1.0 to Android 11 based One UI 3.0, Samsung has brought us a lot of exciting new features and improvements with its every new generation.

Samsung One UI developed for different devices such as foldable phones, smartphones, tablets. Even it also powers the company’s smartwatches. Here’s a lighter version of One UI – One UI Core is also made for Samsung’s budget smartphones. Before the One UI, Samsung’s devices came with Android OS based, Samsung Experience UX.

As we know, Samsung has recently unveiled the third generation of its custom skin – One UI 3.0. The One UI 3.0 built on Google’s Android 11 and is the successor of its One UI 2.0 (Android 10). Meanwhile, Samsung has also brought two more versions between the One UI 2.0 and One UI 3.0 – One UI 2.1, and One UI 2.5. Let’s take a brief look at them.

One UI 2.1:

The One UI 2.1 (Android 10) has exclusively released pre-installed with the latest flagship smartphones of Samsung’s S lineup – Galaxy S20, S20+, and S20 Ultra. Followed by other eligible devices of the company has received it as an OTA, while some are still receiving this version of One UI. The One UI 2.1 doesn’t bring major features and UI changes.

One UI 2.5:

Samsung One UI 2.5 is also based on Android 10 and it is released alongside the Galaxy Note 20 series smartphones in August this year. The One UI 2.5 adds some major and improved features including Samsung DeX, a more powerful keyboard, enhanced AOD, SOS features in Messages, and much more. The One UI 2.5 is the last major update for several Samsung smartphones including the Galaxy S9 and Note 9 models.

So, what has changed between the One UI development compared to last year?

If we take a look at the development of One UI, it shows how Samsung has improved its software development ecosystem. And we may find our answers by comparing One UI 2.0 and One UI 3.0.

Rollout Start Date:

Android 10 based One UI 2.o:

Samsung has released the One UI 2.0 built on Android 10 OS from November 28, 2020, for the Galaxy S10e, S10, S10+, and S10 5G phones from a well known European country, Germany.

Android 11 based One UI 3.0:

Samsung and Verizon (Mobile Carrier of the US ) have opened the door of the Android 11 based One UI 3.0 for the Galaxy S20 units in the US on December 2, 2020.

The stable update release dates for both One UI 2.0 and One UI 3.0 are too similar. Samsung has impressively maintained to provide a new platform upgrade for its eligible smartphones.

Beta Testing Program:

Samsung One UI 2.0:

Last year, Samsung has started the One UI 2.0 beta testing program for the Galaxy S10 models on October 14. Followed by the Galaxy Note 10 series and older flagships like the Galaxy S9 and Note 9 also joined the One UI 2.0 beta testers family.

Samsung One UI 3.0:

Samsung announced the One UI 3.0 public beta program for the Galaxy S20 series smartphones on September 29, 2020. Following its announcement, the Galaxy Note 20 series phones also listed for the One UI 3.0 beta testing program.

The company hasn’t forgotten inviting in the beta testing for older flagships like the Galaxy Note 10 and S10 models. This year, the Galaxy S20 FE, Galaxy Z Fold 2 and, Galaxy Z Flip have also joined the list of smartphones that are experiencing the latest features of the One Ui 3.0 before its public release.

How Samsung improved its software system?

With the One UI 3.0, Samsung has also extended the device participation in the beta testing program. So far, we’ve seen that the mobile service provider carriers are known for a late update rollout for their locked phones. This time, Samsung and Verizon US together proved it false by their good understandings of the Android 11 development.

Till now, Samsung Galaxy S20 smartphones locked on Verizon and T-Mobile carriers have received the Android 11 based One UI 3.0 update in the US. Furthermore, the Galaxy S20 series smartphone owners from numerous countries across the globe are also getting the Android 11 upgrade via OTA.

Not that all, the South Korean tech firm hasn’t forgotten rolling out security patch updates for other smartphones.  Samsung is simultaneously providing new security updates over the air to its hundreds of device owners who are waiting to get their turn to start experiencing the tons of new features with the One UI 3.0.

Samsung wants to collapse Google’s Android with its updates:

Among several of the One UI 3.0 beta updates, we’ve seen a surprising update. One of the One UI 3.0 beta builds for the Galaxy S20 units arrived having the December 2020 security patch. Samsung has already released December’s security patch 17 days ahead of starting the month of December.

These things clearly show how Samsung has massively improved its software system with the new One UI 3.0 and we can surely expect that Samsung will improve it further.

Hey, Samsung! Galaxy S23’s 5% battery boost is a welcome move, but 25W charging is unacceptable



Samsung Galaxy S22 battery charging

Battery capacity and charging speed are the two key specs that are consumers’ top priorities nowadays. Next year, Samsung will unveil its next-gen Galaxy S line – the Galaxy S23 series, which could feature battery capacity increased by 5% but charging speed stuck at 25W.

With the Galaxy S22 Plus and S22 Ultra, Samsung brought back the 45W charging support, which might not be continued. At the same time, the middle child of the upcoming Galaxy S23 lineup is rumored to boast the same size battery, but Samsung is extending its capacity by 200mAh with dimensity increment.

5% battery increment is a welcome move!

In the recent past, an alleged Galaxy S23 Plus battery passed the SafetyKorea certification, which hints the size of the battery is almost the same as its predecessor. However, a recent Korean media report revealed that the Galaxy S23 Plus flagship will have 5% increased battery capacity, thanks to increased dimensity.

With the same size of the battery, Samsung appears to be offering a 4700mAh capacity to the Galaxy S23 Plus smartphone, which is 200mAh higher than the Galaxy S22 Plus. Well, an additional 200mAh battery capacity isn’t too much but it’s a welcome move for sure!

Samsung Galaxy S22 battery charging

Samsung may be offering higher battery power while keeping the size the same is just amazing. Our flagship will continue its premium design without additional weight or a thicker middle frame. It’s all about technology and innovation.

Really, 45W charger is a hoax?

Various reviewers, general consumers and reputed media outlets had the same feedback about Samsung’s 45W phone charger and its authenticity. A reviewer at CNET revealed that the 45W charger managed to charge the Galaxy S22 Plus slightly faster when starting from 0% over the course of 10- and 20-minute increments.

On the other hand, when plugging in at 25%, the 25W adapter filled a higher amount of battery after 10 and 20 minutes, and the results were the same when charging from 50%. The same feedback has also been conveyed by AndroidAuthority.

As the 45W fast charger seems like just an “on paper” thing, the Korean tech giant might not be continuing the same offer with its next-gen flagship smartphone lineup. The Galaxy S23 Ultra test model has recently passed Chinese 3C certification, which revealed a 25W fast charging feature.

In the United States, OnePlus is offering up to 125W fast charging with the OnePlus 10T, which is a mid-range smartphone. At the same time, Galaxy flagships are stuck on just 25W for years and Samsung calls 25W fast charging, it doesn’t make sense.

Editor’s Pick:

We know the Korean phone maker doesn’t believe in just “on paper” and the numbers game, but then, what about the 200MP camera sensor? Motorola used Samsung’s image sensor and introduced the world’s first 200MP camera smartphone, and Galaxy S23 Ultra is rumored to become the second next year.


The battery capacity and charging speed are subject to consumers’ routines, how much time they can use their phone if away from the charger, and how much time they need to keep their phone plugged in to get it fully charged. What do you think about 25W speed? Is it really “fast charging” against rivals, let us know through social media.

Stable OxygenOS 13 released but Samsung hasn’t surrendered



OxygenOS One UI OnePlus Samsung

Samsung is still testing the Android 13-based One UI 5.0 Beta on Galaxy S22 and Galaxy S21 series devices. And similar to the last year, Samsung got defeated by OPPO & OnePlus in the race for the earliest Android-based custom skin shipment.

10 days ago, OPPO shipped the Stable Android 13-based ColorOS 13 upgrade to its most-recent flagship lineup – Find X5 series. And recently, OnePlus has also released the Stable OxygenOS 13 update, based on Android 13 OS, to the OnePlus 10 Pro flagship.

It means, Samsung got defeated by not only Google (of course, there’s no competition), but Chinese Android vendors – OPPO and OnePlus have also rolled out the Stable Android 13 update for their flagship devices ahead of the Galaxy S22 series.

Well, OnePlus managed to seed the Stable OxygenOS 13 update for its most recent flagship, but, what will happen with it next year, and then? No need to scratch the head, in case you are a true Samsung fan and OnePlus consumers are well aware of the future of so-called flagships.

Sell, forget

Yes, that is what the Chinese phone makers follow, just sell the product and forget about the support. No doubt, the OnePlus 10 Pro started to get the Android 13 Stable update in a very short time after the Pixel release. At the same time, there are a lot of examples of promises that are never fulfilled.

OxygenOS One UI OnePlus Samsung

OnePlus 7 users crying for Android 12

Back in June 2019, OnePlus launched the OnePlus 7/7T series which includes a total of 4 models. These devices are packed with Snapdragon 855 chipset and Android 9 Pie operating system out of the box. OnePlus promised to deliver at least three major OS upgrades, which is becoming true as well but with tortoise speed.

In 2019, Samsung launched the Galaxy S10 and Galaxy Note 10 series devices that received the Stable Android 12 update earlier this year. Moreover, the company released another incremental upgrade – One UI 4.1 to these older flagships in the month of March.

OnePlus, on the other hand, started the Android 12 Beta program for the OnePlus 7 series device in early July to provide the OxygenOS 12 custom skin. The Open Beta program is available for consumers in limited countries, and the remaining are still running Android 11, while Google’s going to begin preparation for Android 14.

Samsung sold a huge number of Galaxy S10 and Note 10 series devices, which means the company has already deployed the Android 12 upgrade for millions of consumers worldwide. Meanwhile, OnePlus is just managing to become “first” for newer models and it’s already last for older ones!

Samsung should boost up Android deployment

Samsung is the king of the Android updates segment, even, though Google is far away with its “handful” of Pixel smartphones. The former plays a big role in the Android ecosystem by shipping the highest numbers of Galaxy devices, with support for up to 4 OS upgrades to flagships and select-mid-rangers.

Google’s still stuck on 3 OS upgrades for its Pixel flagships, while the security patch updates promise is the same as Samsung’s of five years. As the Korena tech giant is a leading smartphone brand with worldwide reach, it should further improve its Android development department for faster rollouts.

“At least, Samsung is not bias like vendors from China.”

One UI 6 or 5.1 should bring Large Folders feature



One UI Large Folders Feature anted

With iOS version 14, Apple introduced a new way called App Library to find and organize the apps so iPhone consumers can see what they want and where they want. In iPhones, we can reach this destination by swiping Left until we get to the App Library.

Inside this section, iOS puts all the apps in different folders category-wise. For example, if you have Instagram installed, then you can find it from a big folder named Social in the App Library. This functionality is amazing, which further become interesting when Huawei managed to copy it for its devices.

iOS App Library

iOS 14 App Library

By introducing HarmonyOS, its self-developed operating system, Huawei presented the Large Folders feature for smartphones. This feature is almost similar to that one iSheeps got with the iOS 14 on their iPhones’ App Library section.

Instead of creating a dedicated page on the homescreen, HarmonyOS introduces the Large Folders feature on the regular pages. Users can easily create Large Folders on the homescreen by just combining two apps together to create a regular folder.

Once done, tap and hold the newly created folder then the OS provides you with an option to Enlarge the folder. The enlarged folder occupies the space of a total of 4 apps (2×2) on the homescreen. The interesting this about this feature is that you will be able to put 9 apps within the same space occupied by 4 apps, thanks to Large Folders.

Apps placed inside the Large Folder can directly be opened from the homescreen, however, you can tap on a Lil bit of blank space in the folder to expand it. Similar to the homescreen and regular folders, we can add even more than 9 apps, that can be found on the 2nd page inside the folder.

While Huawei has further improved the Large Folders functionality with its next-gen HarmonyOS version, other Chinese smartphone vendors have also included the same feature in their custom skins. OPPO (with ColorOS 13) is the most recent entry in the list of OEMs providing the Large Folders feature.

As OPPO failed to provide a clean appearance to the Large Folders’ functionality, HarmonyOS 3.0 take it to the next level. Well…, Chinese phone makers are introducing new user-friendly features with their custom skins based on the Android operating system, regularly, but, Samsung is far behind.

On the other hand, there’s nothing wonderful addition spotted in the One UI 5.0, based on Android 13 so far. At least, Samsung should add the Large Folders feature with the upcoming builds of the One UI 5.0 software for the Galaxy devices.

If it doesn’t happen, I’m dreaming to use the Large Folders feature with the forthcoming One UI 5.1, based on Android 13, or the Android 14-based One UI 6.0, which will arrive over a year later from now on. What do you think about it? Should Samsung bring the Large Folders feature, let us know through social media.
