UNISOC's Flagship 4G T7300 Chipset to Drive UMIDIGI's New A Series!

It appears that UMIDIGI is poised to shake up the 4G smartphone market. New reports suggest the company is preparing to launch a brand-new A series, with the first model expected to debut UNISOC’s latest flagship chipset, the T7300. The device is coming as UMIDIGI A78 and will feature the new chipset. It is built on a 6nm process. This chip is being touted as one of the most powerful 4G processors available today. But does it live up to the hype? Let’s dive into what’s been revealed so far.

A leaked comparison chart places the T7300 alongside rivals like MediaTek’s Helio G100 and Qualcomm’s Snapdragon 685. On paper, the T7300 appears to have a significant edge in several areas: its dual Cortex-A78 performance cores outperform the A76 cores in the G100 and the older A73 setup found inside the Snapdragon 685.

Connectivity and multimedia also get a major boost. The chip supports Wi-Fi 6, Bluetooth 5.4, and GNSS L1+L5 dual-band positioning with inertial navigation. By contrast, competing chips are stuck on Wi-Fi 5. Early benchmark whispers suggest scores exceeding 510,000 points, noticeably ahead of the Helio G100’s ~430,000 points.

The T7300 also packs UNISOC’s 7th-gen Vivimagic imaging engine with a quad-core ISP capable of handling 108MP photos, 32MP video, and dual 16MP ZSL captures. In practice, this means features like AI scene recognition, multi-frame RAW, HDR boosts, and advanced night mode could make their way to mid-range 4G phones.

Gamers should take notice, too. The so-called Miracle Gaming Engine promises smoother frame rates and fewer drops, with support for popular titles like Honor of Kings, Mobile Legends: Bang Bang, and Free Fire at up to 90fps high quality. Dedicated gaming network optimization is designed to cut down on lag spikes.

For audio, the T7300 steps up with Hi-Fi4 technology, offering cleaner calls, immersive playback, and even advanced tools like AudioZoom 3.0 and AudioFocus 1.0. Whether you’re vlogging or recording on the go, the chip aims to deliver flagship-level sound control in a mid-range package.

Alongside the chipset, a leaked promotional poster appears to reveal the first phone in the new series: the UMIDIGI A78. If the details are accurate, it features a 6.7-inch display with a smooth 120Hz refresh rate, a 64MP main camera, and a 6,300mAh battery supporting 45W fast charging. That’s 300mAh more than the company’s previous G100 series, paired with quicker top-ups.

Durability also plays a major role here. The UMIDIGI A78 is rumored to feature IP64 water resistance and MIL-STD-810H military-grade certification, making it a rugged option for users who demand reliability.

If these leaks prove accurate, UMIDIGI could be positioning the UMIDIGI A78 — and the wider A series — as one of the strongest contenders in the 4G market. The T7300 chipset not only outpaces many of its rivals on paper but also introduces premium features like Wi-Fi 6, advanced gaming support, and Hi-Fi audio to an often-overlooked segment.

While official confirmation is still pending, excitement is already building. If UMIDIGI’s upcoming launch delivers on these promises, the UMIDIGI A78 might not just be another mid-range phone. It could be a great showcase of how 4G smartphones can still be interesting and packed with new technologies.
