Evidence-based overview

G100x technical sheet

The Umidigi G100x runs Android 15 with Google Services and uses a 6.9-inch IPS LCD in a 21:9 format. Its documented display specifications include 720 × 1,640 pixels, 260 ppi, 500 nits of peak brightness and a 120 Hz refresh rate. The fingerprint sensor is mounted on the side.

Processing comes from the MediaTek Helio G81 with an octa-core CPU and Mali-G52 MC2 GPU. The specification lists 4 GB of RAM and up to 128 GB of expandable eMMC 5.1 storage. AnTuTu v11 is listed at 345,000; this is recorded specification evidence, not a NeoTeo test result.

The 5,200 mAh Li-Polymer battery supports 20 W fast charging, while the data also lists 20 W wireless charging. The main rear camera has 32 Mpx, an f/1.8 aperture, autofocus and 1080p video at 30 fps. It is joined by 2 Mpx macro and depth cameras, with an 8 Mpx front camera. Optical image stabilization is not listed for the main rear camera.

This setup may suit users who prioritize a large display, stereo speakers, dual-SIM support, 4G LTE and expandable storage. The documented compromises are 4 GB of RAM, eMMC 5.1 storage, 500-nit peak brightness and the lack of OIS. Battery endurance is not established by the supplied evidence.

Highlights

  • 16.9-inch IPS LCD with a 120 Hz refresh rate
  • 25,200 mAh battery with 20 W fast charging
  • 3Up to 128 GB of expandable storage
  • 4Stereo speakers and a 3.5 mm audio jack

Things to consider

  • 14 GB of RAM and eMMC 5.1 storage
  • 2Peak display brightness is listed at 500 nits
  • 3The main rear camera has no optical image stabilization
