We hold the root of trust on our own hardware and maintain our own Android and kernel lifecycle. That is why our devices keep receiving security updates long after the rest of this market has stopped.

Why they stay secure
Every piece of software on the device is cryptographically verified before it starts, and limited to what the customer has selected.
The chip maker's security code is closed and rarely updated. We replaced the most sensitive pieces with modern versions that are heavily audited and widely trusted.
Devices that left the factory on Android 13 run Android 17 today. Updates reach devices that are already deployed, and a bad update undoes itself.
Proof
Researchers found this in a chip family used across budget phones from Motorola, Xiaomi and Realme. The chip maker never answered them. This is typical, not rare: more than 40% of Android devices in the world no longer receive security updates at all.
We patched the modem ourselves, made sure it cannot change the kernel's code, and hardened the interface between them.
Capabilities
Scales, medical instruments, industrial controllers, payment terminals, sensors. Ordinary Android blocks an app from reaching them, so these products cannot be built on a typical tablet.
Ordinary Android keeps an app locked in a sandbox. On our devices your app can change device settings, manage network and power, lock the screen to one app, reboot on a schedule, install its own updates, and keep running instead of being shut down to save battery.
Each device proves, in hardware, that it is a genuine OhrTech device running exactly the software you approved.
What we own
Who it is for
Scales, instruments, controllers and payment terminals your app has to talk to directly. Ordinary Android blocks that. Ours grants it to your app alone.

Eight eMudhra (emSign) certificate authorities were created with private keys that anyone can recover. Unpatched Android trusts certificates they issue, so anyone on the network path could impersonate any HTTPS site to apps and web views. We released a fix on October 21, the day after the compromise was disclosed.
A flaw in Unisoc's kernel DVFS driver lets a privileged local process crash the device. Unisoc lists the T7200, the current name of the chip in OhrTech devices. We fixed it, along with a related flaw we found in the same driver.
A flaw in how Unisoc's modem firmware validates network input can be triggered remotely, with no user interaction. Unisoc lists the T606 as affected. OhrTech devices now ship modem firmware that includes the fix.
