| Claim | Reality | |-------|---------| | Increase signal bars | . Signal bars are a human-readable representation of RSRP. Changing build.prop might alter the mapping of dBm to bars, but not the actual dBm. | | Faster download speeds | Minimal, if any . Your carrier limits maximum speed based on plan, congestion, backhaul, and radio conditions. TCP buffer tweaks can help on high-latency or lossy connections, but difference is often under 5-10%. | | Reduce ping | Sometimes . Enabling VoLTE or forcing LTE-only mode can reduce latency by 10-30ms compared to falling back to 3G for voice. But core routing is carrier-controlled. | | Unlock extra bands | Almost never . LTE bands are hardware- and firmware-defined. A Magisk module cannot enable a band your modem doesn’t support. | | Carrier Aggregation | Rarely . In some phones (e.g., OnePlus, Xiaomi), modules can re-enable CA combos present in modem firmware but hidden in the OEM's carrier profile. Requires deep knowledge. |
