Our verdict
The FOSSiBOT F107 Pro is a conditional choice for camping, field work and long trips away from power, where a phone that doubles as a power bank and flashlight saves carrying extra gear. We would not buy it as an everyday pocket phone, as a proven night-vision tool, or as a long-term primary phone on AT&T or Verizon. Its appeal is a 28,000mAh battery, IP68 and IP69K sealing, a 6.95-inch 120Hz screen and a bright built-in flashlight. Its costs are a 910-gram body, a carrier list built around T-Mobile, unverified camera claims and no stated update period.
Research-based review · Not scored · Checked November 6, 2026. We have not used an F107 Pro. This assessment compares FOSSiBOT’s product pages, store data and policy pages with launch coverage and one hands-on unboxing. It contains no FlawCheck battery, charging, camera, brightness, network or durability measurements.
This review covers the FOSSiBOT F107 Pro in gray with 12GB of RAM and 512GB of storage, sold on FOSSiBOT’s store with a US plug. It does not cover the regular F107 or other FOSSiBOT models. For the wider lineup, see our FOSSiBOT phones guide. [1]
Investigate if you use T-Mobile-based service and value one heavy device over a phone plus a power bank.
Wait for independent samples. The 0.0005 lux claim comes from FOSSiBOT and uses a 2MP sensor.
Avoid if you need AT&T or Verizon, a light phone or a known update horizon.
Three takeaways govern this review: a 28,000mAh battery comes with 910 grams; “30GB RAM” is 12GB of real memory; and a “5-Year Limited Warranty” banner is not the same as a five-year warranty on this phone.
Strengths and weaknesses
The strongest reason to consider the F107 Pro is endurance. FOSSiBOT lists a 28,000mAh battery, 66W wired charging and 10W reverse charging, so the phone can top up other devices. These are listed features. We have not tested them. [1]
- 28,000mAh battery with reverse charging
- The phone weighs 910g and is almost 4cm thick.
- IP68, IP69K and MIL-STD-810H listed
- Liquid damage is excluded from the warranty.
- 200MP main camera and night vision
- Electronic stabilization only; night vision is a 2MP sensor.
- 512GB storage, microSD
- The card shares a hybrid slot with the second SIM.
These are reasons to investigate or avoid a purchase. They are not measured failure rates. Most of the remaining uncertainty is about the carrier, the warranty wording and the update period, not the phone’s basic design.
| Claim | What the sources show | What to check |
|---|---|---|
| 30GB RAM | FOSSiBOT's own wording is "12GB+Up To 18GB Expansion". Only 12GB is physical memory; the rest is storage used as virtual RAM.Source | Compare phones on the 12GB figure. Our virtual RAM guide explains the difference. |
| 5-Year Limited Warranty | The banner appears on the US store, but the US warranty table lists the 2 + 3-year extension for power stations and expansion batteries only, and does not list phones. The global warranty page says 24 months.Source | Plan on 24 months. Get any longer term for the phone in writing before ordering. |
| World's first rugged phone with Starlight night vision | A 2MP night-vision camera with a claimed 0.0005 lux sensitivity. We found no independent test of the claim.Source | Treat it as a low-resolution viewer for dark scenes, not a replacement for a thermal or security camera. |
| Up to 2GB TF card | The product page says "UP to 2GB TF Card", which is almost certainly a typo. Launch coverage gives 1TB or 2TB, and the card shares a hybrid slot with the second SIM.Source | Choose between a memory card and a second SIM. Do not rely on cards above 1TB without a test. |
| Compatible with major U.S. carriers | The list names T-Mobile and carriers that use T-Mobile's network. AT&T and Verizon are not named, and we could not read an official band list.Source | Check the IMEI with your carrier, and plan on T-Mobile or a T-Mobile-based carrier. |
| 28,000mAh battery with 66W fast charging | The battery figures are FOSSiBOT's and vary between sources. New Atlas quotes about 4.5 hours for a full charge. No FlawCheck battery test.Source | Plan for overnight charging and a 66W USB-C charger. |
Design and portability
FOSSiBOT lists the F107 Pro at 190.1 × 90.6 × 39.95mm and 910 grams, figures repeated by New Atlas and Mobilissimo’s unboxing. FOSSiBOT’s store data lists the same 910 for each variant. We have not weighed or measured a unit. [1][2][3]
Almost 4cm thick and 910 grams.
- Height
- 190.1mm
- Width
- 90.6mm
- Depth
- 39.95mm
- Weight
- 910g
- Battery
- 28,000mAh
- Screen
- 6.95in
Plan for a belt holster, a bag or the rear strap. This is not a phone for a trouser pocket.
At almost 4cm thick, the F107 Pro is closer to a power bank with a screen than a phone. Mobilissimo found screws in the box for a rear strap that holds the phone on your hand. A holster, a backpack strap or a car mount is the practical way to carry it. Notebookcheck called it “chunky, even for a smartphone of its rugged category.” [1][2]
The flashlight is a real extra for field use. FOSSiBOT lists a “50m Beam Distance Super-bright Flashlight”, and New Atlas reports 372 lumens. We have not measured either figure. [1]
Display and everyday usability
The screen is a 6.95-inch IPS panel at 1080×2460 with a 120Hz refresh rate behind Corning Gorilla Glass 3. That is large and sharp enough for maps and video. FOSSiBOT does not list a brightness figure, and we have no brightness measurement, so we cannot say how readable it is in direct sun. [1][2]
Mobilissimo reports a fingerprint sensor in the power button, a dedicated flashlight button and a red shortcut key, which are useful with gloves. The USB-C port has a rubber cover. We have not tried the controls with work gloves. [1]
Performance, memory and storage
The F107 Pro uses a MediaTek Dimensity 7300, a 4nm chip that Notebookcheck describes as “mid-range”. That is enough for calls, maps, messaging and video. We have no performance testing and do not judge gaming. [1]
FOSSiBOT advertises “30GB RAM”, but its own wording is “12GB+Up To 18GB Expansion”. Only 12GB is physical memory. The extra 18GB is storage set aside as virtual RAM, which Notebookcheck noted makes the headline “60% software-based”. Our guide on whether virtual RAM makes a phone faster explains why the 12GB figure is the one to compare. [1][2]
Storage is 512GB. The product page says “UP to 2GB TF Card”, which is almost certainly a typo; Root Nation reports support for 2TB cards and PhoneArena reports 1TB. Mobilissimo reports a hybrid slot, so a memory card takes the place of the second SIM. [1][2]
Cameras and night vision
FOSSiBOT calls the F107 Pro the “World’s First Rugged Phone with Starlight Night Vision”. Root Nation and PhoneArena report a 2MP AX620Q night-vision sensor with an f/1.0 lens and a claimed sensitivity of 0.0005 lux. That figure is FOSSiBOT’s. We found no independent test, and a 2MP sensor produces low-resolution images by design. [1][2]

- 50MP wide / macroSony IMX766 sensor shared between wide-angle and macro useClaimed
- 2MP Starlight night visionAX620Q sensor, f/1.0, "0.0005 lux"; low resolution by designUnverified
- 32MP frontSony IMX616 sensorClaimed
Mobilissimo's unboxing noted there is no optical image stabilization. We have seen no independent samples and do not judge image quality.
The main camera uses a 200MP Samsung S5KHP3SP03 sensor, with a 50MP Sony IMX766 for wide-angle and macro shots and a 32MP Sony IMX616 on the front. Mobilissimo noted there is no optical image stabilization, only electronic stabilization. We have not seen independent sample images and do not judge their quality. [1][2]
Battery and charging
The battery is a 28,000mAh pack. FOSSiBOT’s endurance figures differ between sources: New Atlas and Root Nation quote “30 days on standby” and 133 hours of music, PhoneArena quotes “2,800 hours of standby”, and Mobilissimo lists 33 hours of music. All agree on 40 hours of video. None of these are FlawCheck measurements. [1]
Charging is 66W over USB-C, and Mobilissimo found a 66W charger and a USB-C cable in the box. New Atlas says a full charge takes “around 4.5 hours”. There is no wireless charging. 10W reverse charging lets the phone top up other devices. We have no charging-time measurement. Our guide on whether fast charging damages a battery covers the trade-offs. [1][2]
Connectivity, software and ownership
US carriers: plan on T-Mobile-based service
FOSSiBOT’s US store says the F107 Pro is “Compatible with major U.S. carriers including: T-Mobile, Boost Mobile, Metro by T-Mobile, Straight Talk, Consumer Cellular, Mint, Metro, Ultra Mobile, Red Pocket Mobile, Good2Go Mobile”. The list names T-Mobile and carriers that use its network. It does not name AT&T or Verizon. [1]
We could not read FOSSiBOT’s official band list, and we found no statement on VoLTE or Wi-Fi calling for US carriers. We did not check an IMEI or activate a unit. Check the IMEI with your carrier before buying, and keep the return window in mind. [1]
Third-party listings report NFC and dual nano-SIM support. We did not find an eSIM listing.
No stated update commitment
The product title lists Android 15. We found no published FOSSiBOT commitment for the number of Android upgrades, security patch cadence or a security-support end date for the F107 Pro. New Atlas noted “there’s no word on future OS update support.” We could not confirm the current build or patch level. [1][2]
Warranty and returns need written clarification
FOSSiBOT’s warranty page says “The warranty period for FOSSiBOT products is 24 months”, and the product page shows “2-year Warranty”. The US store shows a “5-Year Limited Warranty” banner, but the US warranty policy lists the two-year term with a three-year extension only for power stations and expansion batteries and does not list phones. We use 24 months. [1][2][3]
The same global warranty page offers “a 30-day money back guarantee” and also asks buyers to begin a return “within 15 days from the original shipment date”. The separate return policy gives 30 days for items that are “complete, unused, and in its original packaging”, and the buyer pays round-trip shipping when there is no defect. Ask which terms apply to your order before you open the box. [1][2]
The warranty excludes damage from “excessive heat, cold, liquids or other external causes”. IP68 and IP69K ratings do not mean a water claim will be covered. Our IP68 and water-damage guide explains that difference. FOSSiBOT lists IP68, IP69K and MIL-STD-810H, and New Atlas reports immersion to 1.5 meters for about 30 minutes. We did not find an independent test report for the F107 Pro. [1][2]
Alternatives and value
Our reference offer is the US / Gray variant on FOSSiBOT’s global store at $529.99, with a crossed-out $549.00. FOSSiBOT’s US store showed $589.00 for the same phone during a Black Friday promotion. Both are storefront observations from November 6, 2026, not delivered totals. [1][2][3]
| Item | What we observed on November 6, 2026 | Status |
|---|---|---|
| Global store, US / Gray | $529.99, compare-at $549.00 | Listed as available |
| US store | $589.00, compare-at $689.00 | Same phone, different price |
| Launch sale (July 2025) | $439.99 from a $549 list price | Historical, not today’s price |
| In the box | 66W charger, USB-C cable, strap screws | From Mobilissimo’s unboxing |
| Returns without a defect | Buyer pays round-trip shipping | Return policy |
| Delivered total | Not checked | Unavailable |
We have no verified delivered total. Coupons and promotional prices on FOSSiBOT’s stores change often and are not included here. A crossed-out price is not a saving we can verify.
The alternatives depend on the job. A lighter rugged phone plus a separate power bank costs you a second device but lets you leave the weight at camp. FOSSiBOT’s smaller F116 Pro shows the opposite trade-off. If you need a carrier-sold rugged phone on AT&T, see our Sonim XP3plus 5G review.
Three ways to cover the same job.
Final verdict
Consider the F107 Pro if you want one rugged device that runs for days and charges your other gear, you use T-Mobile or a T-Mobile-based carrier, and the 910-gram weight suits how you carry it. Confirm the carrier with the IMEI, the warranty term in writing and the return terms before buying.
If you need a pocketable phone, AT&T or Verizon, tested night vision or a known update horizon, we would choose a different device. We are withholding a numerical score because we have not tested the phone or verified a full transaction.
Frequently asked questions
How heavy is the F107 Pro? FOSSiBOT lists 910 grams and 39.95mm thick. We have not weighed a unit.
Does it really have 30GB of RAM? No. It has 12GB of physical RAM, and up to 18GB of storage can be used as virtual RAM.
Does it work on AT&T or Verizon? FOSSiBOT’s carrier list names T-Mobile and T-Mobile-based carriers only. We did not test any carrier.
