Am I the only one who dislikes the aspect ratios of modern phones?

20:9 makes most videos have black bars. Keep the size similar but make it 16:9.

After 12 Years, I Finally Left Samsung

I finally pulled the trigger and ordered a Motorola Razr fold, ending what has been a 12-year journey with Samsung.

Ironically, Samsung was also the company that brought me back to Android. My first Samsung device was the Galaxy S2 during my college time. I absolutely loved it and used it for a long time before moving to the iPhone 5S. At first, the iPhone felt premium and polished, but over time I found iOS too restrictive for my liking. The freedom and flexibility I had on Android was something I genuinely missed.

So I came back with the Galaxy S7. And after that, I stayed. S series, Ultra series even the Z series. Samsung became my default choice. Not because it was perfect, but because it represented something that Apple didn't: freedom, customization, experimentation and pushing hardware boundaries. I still remember getting the option to out SD card back was such a reliever after coming back from 5s. That's what made many of us Samsung fans in the first place.

But over the last few years, I've felt that something changed. Samsung's software is still excellent. One UI is probably the best Android skin in my opinion. The ecosystem is polished. The support is great.

But hardware-wise, it feels like the company has become increasingly conservative. and has become like apple (which they used to mock earlier in their ads)

As a customer, it became difficult to justify flagship prices when competitors were offering significantly larger batteries, faster charging, thinner foldables and more aggressive hardware innovation.

The biggest example for me is battery technology. We are in 2026, yet Samsung's flagship battery strategy feels largely unchanged. Ultras are still stuck at 5000 mah. Meanwhile, competitors are pushing 6000 - 7000 mAh batteries and 100W+ charging at half the price.

I know Samsung prioritizes safety, reliability, and long-term support and those things matter. But innovation matters too.

What finally pushed me over the edge wasn't that Samsung became bad. It just became what I wanted to avoid and chose Samsung for.

It was also that I realized I was staying partly because of the ecosystem and habit. And that's not a good enough reason for me to spend flagship money.

So for the first time in over a decade, I'm stepping outside the Samsung ecosystem. Maybe I'll love it. Maybe I'll come back in a few years.

But I think it's healthy to occasionally challenge brand loyalty and choose products based on what serves your needs today rather than what served them in the past.

The phone hasn't arrived yet, but after 12 years with Samsung, this definitely feels like the end of an era.

A/B Users are more secure than Private Space

# TL;DR

From a forensic or security perspective, despite the additional authentication layer for Private Space, data is more vulnerable than a separate, second user.

# Private Space

Private Space uses a file-based encryption model where user-specific data transitions from BFU-restricted to AFU-accessible once the primary user unlock occurs. Here is the breakdown:

BFU (Before First Unlock): Device just rebooted, no authentication yet. Only Device-Encrypted (DE) storage is accessible. Credential-Encrypted (CE) data remains locked.

AFU (After First Unlock): User has authenticated once post-boot. Both DE and CE storage are accessible with derived keys.

Private Space uses file-based encryption and stores its data in the CE partition. Once the device reaches AFU state:

The encryption keys for Private Space are available in memory

Private Space itself still requires separate authentication to access

The underlying storage is decrypted and accessible to the system

# Second User

A second user profile remains in a BFU-like (Before First Unlock) state regarding its own data encryption keys until that specific user authenticates, even if another user (the primary owner) has already authenticated and put the device in AFU.

Here is the breakdown:

Per-Profile Key Derivation: Android File-Based Encryption (FBE) generates unique credential-encrypted (CE) keys for each user profile. When User A unlocks the device, only User A's CE keys are derived and loaded into memory.

Isolation: User B's CE keys remain locked and inaccessible. The file system permissions prevent User A's session from reading User B's private data or deriving User B's keys without User B's specific authentication credential.

Shared Storage Exception: The only data accessible to both users while User B is "locked" is the shared storage area (e.g., /sdcard if not strictly partitioned, though modern Android isolates this too). Private spaces and individual app data for User B remain encrypted and effectively in a BFU state relative to User A's session.

Therefore, the device being in AFU because of User A does not transition User B to AFU. User B stays secure and encrypted until they personally unlock their profile.

# Conclusion

Choose a second user profile for robust security against physical seizure and Private Space for everyday convenience where absolute isolation is less critical than usability.

Today I learned…DeX

I am new to the Android phone OS..kinda. Never owned one, but knew how to teach people how to use their phone on a basic level. I now own a S26 Ultra solely for work, daily driver is iPhone 16 Pro.. I also use Linux on most of my computers so; the comparison of how DeX works currently is not far off from Raspberry Pi OS. Maybe leaning into Fedora/Ubuntu ways. I’m all for it.

Academic Survey Smartphone OS Loyalty & Switching Costs — MBA Thesis Survey (iOS/Android users in the UK & Europe, ~10–12 min)

Hi r/Android

I'm an MBA candidate at Maastricht School of Management (Netherlands) and I'm currently collecting data for my thesis on perceived switching costs between iOS and Android and how they influence user loyalty in the European smartphone market.


If you've ever thought "I'd never switch from iPhone" or "Android just makes more sense for me" — this study is basically about why that feeling exists and how strong it really is.


Who can participate:


\- 18+ years old
\- Currently using an iOS or Android smartphone
\- Residing in Europe and in the UK


Details:


\- ⏱ \~10–12 minutes
\- 🔒 Fully anonymous
\- 🎓 Academic research only — no marketing, no data selling
\- 🏛️Hosted on Qualtrics via Maastricht University


👉 Take the survey here: https://maastrichtuniversity.eu.qualtrics.com/jfe/form/SV\_cMuOKUJJxMi9w6a
