What to do if OPPO A55s signal is bad
Bad signals are common to all mobile phones. This is not because our infrastructure is not good, nor is it a technical problem. The main reason is that in terms of signal shielding, one is physical shielding, such as building walls, and the other is signal interference, mainly from other high-power electronic devices. What should we do if the OPPO A55s mobile phone encounters bad signals? The following editor will teach you some solutions.
What if the OPPO A55s signal is bad
1. Check the mobile phone protective case: the mobile phone uses metal or magnetic protective case or bracket. Such protective case and bracket have an impact on the mobile phone signal. It is recommended to take them off and try.
2. Troubleshoot environmental reasons: In some areas, the mobile phone may have no signal or poor signal due to the lack of coverage of the operator's network. It is recommended to compare with other mobile phones of the same operator in the same location.
3. Restart the phone: Try to restart the phone to reload the SIM card and see if the SIM card can be recognized.
4. Check the SIM card: the SIM card can be reinstalled to confirm that the SIM card is consistent with the mobile phone installation logo and in good contact with the mobile phone; If conditions permit, you can replace another SIM card that can be used normally to the phone for comparison to confirm whether it is the phone or the SIM card.
5. Check the phone settings: check the flight mode to see if there is an "airplane" icon in the status bar of the phone. If there is an "airplane" icon, please turn off the "flight mode" in [Settings] or [Settings> Other Networks and Connections].
Switch the data card. If the mobile phone is installed with dual cards and one card has no signal, you can enter [Settings; Dual card and mobile network] to switch whether the data card can be restored.
From the above information, the main reasons for the poor signal of OPPO A55s are signal interference and signal coverage. If it is the former, the source of interference should be eliminated. If it is the latter, it is necessary to change the place. My favorite friends can continue to pay attention to the editor.
