Weak signal / calls dropping

Calls cut off mid-way or the signal bars stay stuck at 1–2? Fixes from both the hardware and settings angles are below.

Steps

  1. Enable Wi-Fi Calling
    If your home Wi-Fi is good, turn on Settings > SIM > Wi-Fi Calling — calls will go over the internet and never drop.
  2. Select the network manually
    In Settings > SIM > Network Operators, turn OFF 'Choose automatically' and manually select your carrier. Sometimes the phone latches onto a weak tower.
  3. Remove metal cases
    Thick metal or magnetic phone cases block the signal — test with the cover removed.
  4. Carrier settings update
    Install Settings > System > Software Update and carrier-related updates — they include network fixes too.
  5. Replace an old SIM
    SIM cards that are 5–7 years old can cause signal problems. Get a same-number new SIM from a carrier franchise (usually free/cheap).
  6. Report to the helpline
    If everyone in the area has the same problem, complain to the helpline — only the carrier can fix a tower issue.
