Long-promised review of the PDC680 by YL3IM — better late than never
The radio exists in different versions:
* PDC — DMR/FM
* PTC — TETRA
Advantages
➕ A hybrid of a radio and a full-fledged Android smartphone in a classic form factor with a removable battery, which also serves as the back cover.
➕ Google services can be disabled through standard settings.
➕ Can be rooted if necessary.
➕ Can make calls like a regular mobile phone.
➕ RoIP — essentially digital trunking, Tier 3, using the Internet as transport instead of radio waves. It also works over RF. Supported by BrandMeister, meaning it can be used as a standalone device outside coverage areas without the need to carry a “local hotspot.”
➕ The radio module can be loaded even without Android and used with just the top display.
➕ You can freely troll Apple fans who think they’re superior — “Well, you don’t have this, do you?”
➕ MDMLite supports full Excel import/export without requiring Microsoft Office. Traditional radios demand it, and many fields are missing from the file.
Disadvantages
➖ Runs Android 10, which is outdated.
➖ Google considers the device uncertified — only BASIC_INTEGRITY passes. Can be fixed by rooting. Installing serious apps is not recommended due to potential security issues.
➖ The last firmware update was in July 2024.
➖ When using the network (e.g., in RoIP mode), the battery heats noticeably — up to 40°C.
➖ If the password/key is forgotten, Android recovery mode won’t boot, and fastboot won’t allow a reset either.
➖ Very limited audio settings compared to regular Hytera radios.
➖ Talk Permit tone leaks into the audio path and is heard by the other party. If you disable sounds, you also lose incoming call tones and alerts (e.g., repeater unavailable). The Channel Free Tone depends on the same setting and can’t be disabled separately.
➖ If an external address book exists in Android (in my case, a self-hosted radicale instance via DavX), when reading the radio via MDMLite, its contents are transferred into the radio memory and then deleted from the server during sync — backups are a good idea.
➖ Compared to its predecessor, PDC760, the screen is narrower — making display use less convenient.
➖ Draws attention. You can’t just leave it discreetly on a desk, though sometimes that’s needed.
➖ The tuner is not publicly available.
➖ In RoIP mode, a short press of the PTT is required to activate the group for transmission. After that, you can use PTT normally while talking, listening, then talking again. To return to group scan mode, you must press the red (power) button. Not very convenient. To activate transmission, a timeout after the last reception must pass — you can’t instantly transmit.
➖ If you choose a custom contact for transmission, it's active only until the display turns off or locks. After that, the call defaults back to the preset contact.

Despite the mentioned drawbacks, I don’t regret buying this toy. I only regret not getting it earlier — back in the PDC760 days.
The review may be updated over time if I remember anything else.
