Many Samsung mobile phones will require some form of troubleshooting throughout the life of the device. However, not all troubleshooting has to be complex in order to be effective. With the mass production of cell phone to the global market, phones will ship with certain problems, issues and glitches that manufacturers are not aware of. Luckily, they continually work to resolve these issues once you have the phone in your hands.
Touch Screen or Main Screen Locks
A very common problem for many phones is when the Samsung freezes or locks up while you are using it. There's a very simple formula that will resolve this and help you troubleshoot this problem every time.
While you have the phone turned on, pull the battery out of the Samsung. Now, wait for at least 30 seconds to allow the phone to shut down completely (it is like a minicomputer). After 30 seconds, put the battery back into the phone and put the battery cover on. Now, hit the power button (or the red end call key) to turn the phone back on. Your phone should now function normally and the problem should be resolved.
Insert SIM Card Error
The insert SIM card error message can appear on your phone for a number of reasons. This can even occur on a Samsung if you have the SIM inserted in the phone. While it can be frustrating, there are some quick fixes to this solutions.
SIM cards rely on "contacts" (metal contacts that establish a connection between the card and the phone) to function properly. If this connection breaks or is not stable, it will cause an Insert SIM error. What you need to do is get to the SIM card on your phone. This is typically underneath the battery on the device. Once you get to the SIM card, remove it and reinsert it back into the device, making sure it firmly locks in place. If you need specific help with this, check out your user guide or visit Samsung support for assistance.
After you insert it properly, turn on the phone and it should be working now with full network access.
Cannot Make or Receive Calls
Call functionality can experience issues for a variety of reasons, many of which you can resolve on your own. If you cannot place a call or receive a call on your Samsung, make sure that you have an active signal on the phone. You will also want to avoid electrical or radio interference or obstructions, such as bridges, parking garages or even tall buildings. Again, you will need a solid SIM card connection and also make sure that your battery is fully charged.
Cannot Hear Callers
If you are getting calls on your phone and you cannot hear anyone once you connected, first try to adjust the volume on the phone. If that does not work, make sure that you have an active signal on the phone with good coverage. Sometimes, a headset could cause the problem. If you use one, make sure that it is connected properly or that you have not hit the mute button on the headset.
If you keep on pressing that power key on your phone but cannot get your phone on, make sure that you have charged your battery for at least two hours. Some Samsung phones do not turn on if their battery level is under 25 per cent. While this may be enough juice to run the phone, it cannot power it one. Another check would be to verify that the battery is in the device securely. Make sure it has clicked into place and that the metal contacts on each end are not obstructed in any way.
