The Google Nexus S and the Apple iPhone 4 (the contemporary model) differ fundamentally in their operating systems, design philosophies, and upgrade paths. The Nexus S runs Google’s open-source Android 2.3 (Gingerbread) with a stock, unskinned interface and receives updates directly from Google, while the iPhone runs Apple’s closed iOS 4 with a curated App Store and updates delivered exclusively by Apple.
Background and Release Context
The Nexus S, released in December 2010, was the second phone in Google’s Nexus line, co-developed with Samsung. It was the first phone to ship with Android 2.3 Gingerbread and the first to feature a near-field communication (NFC) chip. The iPhone 4, released six months earlier in June 2010, introduced the Retina display, a front-facing camera, and a complete redesign with a stainless steel frame and glass back. Both phones targeted the premium smartphone market but came from opposite ends of the mobile ecosystem: Google aimed to showcase pure Android, while Apple aimed to refine a single, tightly controlled experience.
Hardware and Design
The Nexus S had a 4-inch Super AMOLED display with a 480×800 resolution, a 1 GHz single-core Cortex-A8 processor (Samsung Exynos 3110), 512 MB of RAM, and either 16 GB or 32 GB of internal storage with no microSD slot. It featured a 5-megapixel rear camera with LED flash and a 0.3-megapixel front camera, plus a curved glass design that contoured to the face. The iPhone 4 had a 3.5-inch Retina display with a 640×960 resolution, an Apple A4 processor, 512 MB of RAM, and 8, 16, or 32 GB of storage. Its rear camera was also 5 megapixels with an LED flash, and it added a 0.3-megapixel front camera for FaceTime. The iPhone 4’s glass-and-steel build felt more premium, but it was also prone to shattering on impact, while the Nexus S’s plastic body was lighter and more durable in drops.
Operating System and Software
The most significant difference lies in the software. The Nexus S ran stock Android 2.3, which offered widgets, customizable home screens, and deep integration with Google services like Gmail, Maps, and Voice. Because it was a Nexus device, it received Android updates directly from Google, bypassing carrier and manufacturer delays—a major selling point at the time. The iPhone 4 ran iOS 4, which featured a simpler, grid-based home screen, a unified notification system (added later in iOS 5), and tight integration with Apple’s iCloud, iTunes, and App Store. iOS was known for its smooth performance, consistent user experience, and a larger selection of high-quality apps at launch. Android offered more flexibility (e.g., default app selection, file system access), while iOS offered more polish and security.
App Ecosystem and Performance
By 2011, the Apple App Store had roughly 500,000 apps, while Google Play (then Android Market) had about 200,000. Apps often appeared on iOS first, and many were optimized for the iPhone’s single screen size, leading to better performance and fewer crashes. Android apps had to support a wide range of devices and screen sizes, which sometimes caused compatibility issues. In real-world usage, the iPhone 4 felt faster in everyday tasks due to its efficient hardware-software integration, even though the Nexus S had a similar processor. However, the Nexus S allowed users to sideload apps, use custom ROMs, and access the file system directly, which appealed to tech enthusiasts.
Common Problems and Known Issues
The Nexus S had a few notable issues: the Super AMOLED screen was prone to burn-in (image retention) on the status bar, the GPS could be slow to lock, and the battery life was mediocre—especially with heavy use. The iPhone 4 had the famous “antenna gate” problem, where holding the phone in a certain way caused signal loss; Apple eventually offered free cases to mitigate it. The iPhone 4’s glass back was also fragile, and the front camera was low-resolution. Both phones suffered from weak batteries—the Nexus S had a 1500 mAh battery, and the iPhone 4 had a 1420 mAh battery—so most users needed to charge daily.
How to Choose Between Them Today
If you are buying a vintage device for collection or experimentation, your choice depends on what you value:
- Choose the Nexus S if you want to explore Android’s early days, install custom ROMs, or use NFC for experiments.
- Choose the iPhone 4 if you prefer a more polished, iconic design and want to experience iOS’s early interface.
- Be aware that both phones are obsolete: modern apps will not run, and security updates stopped years ago. Do not use either as a daily driver.
For practical use, neither phone is recommended—their 3G radios are slow, batteries degrade, and parts are hard to find. They are best as display pieces or for offline retro gaming.
Costs and Availability
As of 2024, both phones are sold as used or refurbished on auction sites and retro tech stores. Prices vary widely based on condition, box, and accessories. A working Nexus S typically sells for $50–$150, while an iPhone 4 can fetch $30–$100, though a sealed, new-in-box unit can go for several hundred dollars. Replacement batteries are cheap ($10–$20), but screens and back panels are scarce. Remember that these phones do not support modern 4G/5G networks, so they cannot be activated on most carriers.
Frequently Asked Questions
Which phone has a better camera?
Both have 5-megapixel rear cameras with LED flash, but the iPhone 4’s camera generally produced more accurate colors and better low-light performance due to better image processing. The Nexus S had a slightly wider field of view and allowed manual focus via touch, but its images were often noisier in dim conditions. Neither camera can compete with even budget modern phones.
Can I still update the software on these phones?
No. The Nexus S is stuck at Android 4.1.2 (Jelly Bean) officially, and the iPhone 4 is stuck at iOS 7.1.2. You can install custom ROMs on the Nexus S (e.g., LineageOS) to get a newer Android version, but the iPhone 4 cannot be upgraded beyond iOS 7. Neither receives security patches, so avoid entering personal information on them.
Which phone is better for hacking or modding?
The Nexus S is far better for modding. Its bootloader is easily unlockable, and there are many custom ROMs, kernels, and recovery tools available. The iPhone 4 can be jailbroken (for iOS 7, there are tools like evasi0n7), but the process is more restrictive and the hardware is less flexible. If you want to tinker, the Nexus S is the clear winner.
Which phone has better build quality?
The iPhone 4 feels more premium with its glass and stainless steel, but that glass is fragile—a drop on a hard surface often cracks the back or front. The Nexus S’s plastic body is lighter and more flexible, so it survives drops better, but it feels cheaper. For durability, the Nexus S wins; for aesthetics, the iPhone 4 wins.
Can I use these phones with a modern SIM card?
Both use micro-SIM cards, which you can cut down from a modern nano-SIM, but the bigger issue is network compatibility. The Nexus S (GSM version) supports 2G/3G on bands that are still in use in some regions, but 3G shutdowns in many countries make it unusable for calls. The iPhone 4 (GSM) similarly supports 2G/3G. In the US, AT&T’s 3G was shut down in 2022, so the phone would only work on 2G (where still available). In Europe, 3G is being phased out. In short, they are not reliable for daily voice or data.
