| Problem | What fixed it most often | Risk | Reports |
|---|---|---|---|
| AI Box Overheating Shutdowns: Heatsink, Cooler or Fan? | Fit a heatsink or a magnetic phone cooler to the box's heat-spreader side (the metal disc on the back of a TBox Ultra), and get the box out of a closed armrest. | Safe | 10 reports |
| AI Box Reboots When Mobile Signal Drops: Hotspot or LTE Mode | Give the box its internet from your phone's hotspot instead of its own SIM, so the modem stops hunting for a signal in dead zones; five of five owners who did this reported the reboots stopped. | Safe | 10 reports |
| Picasou 3 / 3 Pro Running Hot? CPU Monitor and Cooling Fixes | Clamp a magnetic Peltier phone cooler flat against the box and power it from its own USB socket: on the Picasou 3 that ended overheating, including the mobile-data drops that come before a reboot, for both owners who reported back. | Safe | 7 reports |
| Still 60–80 °C With a Cooler: Find What Loads the CPU | Change what the box is rendering: in CarCar Launcher, switch the widget rendering engine and let the launcher's built-in player cover your music app, which lowered temperatures for three of four owners. | Safe | 6 reports |
| AI Box Lags on a Big High-Resolution Screen? Raise Smallest Width | Open Developer options and set Smallest width to 800, so the box draws its interface at a lower density for the large display; on a Geely Atlas that stopped the touch dropouts and lowered the heat for two of three owners. | Safe | 4 reports |
| How Hot Is Too Hot? AI Box Temperatures and How to See Them | Turn on the box's own temperature readout (Settings → Other → Factory settings → 4545 → Other) and watch it on a normal drive with your usual apps. | Advanced | 4 reports |
Reports = owners who said a fix worked for them. Risk: Safe is settings only; Advanced needs ADB or an engineering menu; Brick risk can leave the box unbootable. How we count reports.
