Hot: Marvell Mifi Tool

| Model | Chipset | Known Heat Issue | Fix Available? | |-------|---------|------------------|----------------| | | Marvell PXA1802 | Battery bulging after 1 year | Yes (3G force) | | ZTE MF920 | Marvell PXA1928 | Plastic case melting near SIM slot | Yes (heat sink) | | Huawei E5573s-856 | Marvell PXA1802 | Shuts down in direct sunlight | Partial (undervolt) |
