2. Error on an android smartphone
Android phones that have even been dropped too often can also be the cause of the absence of a signal on the smartphone. That is because the brass signal catcher is enlarged so that the signal capture power is drastically reduced from the end of the vibration when it falls.
3. Weather Factors
The strength or weakness of the HP Oppo signal that we have also depends on the weather factor. The signal capture on the hp oppo a 37 is not good usually the weather is heavy rain accompanied by strong winds and lightning.

This can be due to the region we are in when it does not support the existence of 4g / 3g signals so that Android phones are not able to search for ordinary networks. For that we are able to carry out changes to the android network by entering into the offerings >> Cellular Network >> Select Network Mode "WSDMA / GSM (automatic connection").
6. Software Damage

8. Signal Repair From Operator Services
Operators may be carrying out improvements to their system or tower because there is a problem or adding new features. To improve or add the brand new features, for the sake of safety, electricity will be temporarily turned off in the system or tower so that the impact on cell phone signals that are unstable or disappear.
9. Problems with Third Party Applications
The signal can be influenced by third-party applications that you have installed. These applications may limit signal strength because some features of third-party applications do not match your device.
After knowing some of the factors that create the hp oppo a37 there is no signal above, we will give the following steps to overcome the error of an android cellphone signal so as to create a cellphone with no signal or an android cellphone unable to access the internet. Although the cellphone that we used in the tutorial is missing the signal this time, the Oppo A37 doesn't hurt if we try on other types of smartphone, let's just take a look at the following reviews:
Make sure the sim card is in good condition, starting from the installation of a sim card that is not reversed until the condition is still active, not past the grace period.
Check whether the android oppo phone that we have is in Flight Mode or not? If it is still active then deactivate it and wait a while for the system to refresh the existing network.
Make sure the sim card settings are already active if in the OPPO type using a Dual SIM slot. Sometimes the signal on sim one is there but on sim two a cross appears only because the settings in sim 2 slot are not active yet.
Make sure the condition of the SIM card slot on the android oppo phone in normal conditions, avoid the connector being bent or something closed so as to create a sim card signal not detected on the hp oppo.
Perform an error recovery system by resetting Android settings to factory settings.
If the above steps have not been able to fix the error hp oppo signal and there is no change then it doesn't hurt if you try to investigate the IMEI of the oppo phone. Sometimes the signal does not appear because the SimCard OPPO is unable to be detected by the system because it is caused by a lost or problematic IMEI.
If all the steps above have been carried out and even have carried out the flashing firmware process it also does not produce results in detecting cellular cards on the HP OPPO that we have, then there are problems related to Hardware that must be checked at the nearest OPPO service center in the area we live.
NOTE:
To check IMEI on the OPPO cell the same as other android phones by typing * # 06 #. But if IMEI does not appear, here's how to restore the missing IMEI OPPO smartphone number:
Enter EngineerMode by pressing the dial button * # * # 3646633 # * # *
After that we enter the EngineerMode dish, on the Menu tab select "Select CDS Information" then select "Radio Information".
To fix SIMEI SIM1 select "Phone1" and type the alphabet A and select AT + EGMR = 1.7, "CONTENT IMEI SIM1 HERE". Then click "SEND AT COMMAND" and make sure there is a notification "AT command is sent".
To fix SIMEI SIM2 select "Phone2" and type the alphabet A and select AT + EGMR = 1.10, "CONTENT IMEI SIM2 HERE". Then click "SEND AT COMMAND" and make sure there is a notification "AT command is sent".
The next step is restarting the hp oppo we have (turn it off then on again).
Check IMEI by dial * # 06 # *. If we succeed, the IMEI Oppo a37 has returned and of course it is capable of being used normally because the signal does not disappear anymore.
