# Secondary Display Smartphone Cases The Selfix Case Has a 1.6-Inch AMOLED on the Rear By Michael Hemsworth | Published 2025-12-12 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/selfix-case References: [gsmarena](https://www.gsmarena.com/this_case_will_add_a_second_display_to_your_iphone_17_pro-news-70678.php) & [selfixcase](https://www.selfixcase.com/)  The Dockcase Selfix case has been developed as a supplemental accessory for iPhone 17 Pro users to incorporate onto the device as a way to extend the interface and optimize functionality. The case is equipped with a 1.6-inch touchscreen AMOLED on the rear that will enable users to utilize the 48MP rear camera to snap selfies and videos by acting as a viewfinder. The case can be used without a separate app and connects to the smartphone through the USB-C port on the bottom for efficient, lag-free connectivity. The Dockcase Selfix case also has a microSD card slot hidden inside to offer up to 2TB of additional storage space to work well holding photos and videos, but also for offloading additional data, if desired. ## Trend Insights (Trend Hunter) - Score: 7.6/10 - Popularity: 86% | Activity: 87% | Freshness: 56% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Mobile](https://www.trendhunter.com/mobile) ## Key Themes ### What Makes This Trend Stand Out - **Dual-screen Smartphone Accessories:** Accessories featuring secondary displays are transforming smartphones into more versatile multitasking devices. - **Integrated External Storage Solutions:** Cases with built-in storage options provide seamless data management directly from mobile devices. - **App-free Smart Cases:** Smartphone cases that function without additional apps enhance user experience through simplicity and efficiency. ### Sectors Adopting This - **Mobile Accessories:** The explosion of functional smartphone cases demonstrates growth in the mobile accessories market. - **Consumer Electronics:** Technological advancements in electronic accessories are driving demand for innovative consumer electronics. - **Data Storage Solutions:** The integration of storage capabilities in everyday gadgets reflects innovations occurring within the data storage industry. ## Related on Trend Hunter - [Pro-Level Dual-Display Smartphones](https://www.trendhunter.com/trends/xiaomi-17-pro.md) - [Connected Display Smartphone Cases](https://www.trendhunter.com/trends/reetle-smartink-i.md) - [Rugged Dual-Display Smartphones](https://www.trendhunter.com/trends/ulefone-armor-30-pro.md) - [Storage-Packed Smartphone Cases](https://www.trendhunter.com/trends/sigracen-case.md) - [Durable Pro-Inspired Smartphones](https://www.trendhunter.com/trends/iphone-17.md) - [Backwards-Compatible Smartphone Cases](https://www.trendhunter.com/trends/obsoless-iphone-case.md) - [Tactile Smartphone Keyboard Cases](https://www.trendhunter.com/trends/akko-metakey-case.md) - [Aftermarket Handheld Console Displays](https://www.trendhunter.com/trends/retroid-dual-screen-addon.md) - [Durable Modern Phone Cases](https://www.trendhunter.com/trends/aulumu.md)
