Symptoms
- Signal bars lower than usual in familiar locations
- Calls drop more often since the drop
- Data speeds noticeably slower
Likely causes
- CommonAntenna connector jarred loose by the impactAntennas often run along the frame edges and connect via small clips or connectors that can shift on impact.
- PossibleCracked antenna line in the frame or back glassSome phones route antennas through the frame itself, which can crack from a hard drop.
- PossibleCoincidental carrier or network issue unrelated to the dropWorth ruling out before assuming hardware damage.
What to do
- Check whether the weak signal happens in places where you normally have good reception, to rule out a carrier issue.
- Toggle airplane mode on and off, or restart the phone, to force it to reconnect to the network.
- Compare signal strength to another phone on the same carrier in the same spot if possible.
- Check your carrier's outage map or account status to rule out a network-side problem.
- If signal is consistently worse only since the drop and other phones work fine in the same spot, have a technician check the antenna connectors.
