No network/signal
You maybe located at a network blind spot underground or inside a building, or outside of network coverage. Try moving to another location to obtain a signal or call your network service provider for more information on network coverage. Local network design cannot guarantee 100% call completion rate (the system has a permissible failure range of 2%-5%). In addition, you should check whether there is strong interference in the area that may affect the wireless signal.
Poor/weak signal
Check whether the poor/weak signal is caused by environmental factors. You may get a weak network signal if you are located at a network blind spot underground or inside a building. Try moving to another location to obtain a signal. Sometimes, normal operation of the phone may be affected when the user has exceeded the network capacity. Note: Keep the phone away from antennas while it is switched on. Otherwise, call quality may be affected.
Signal bar is full, but calls cannot be made
This may be caused by temporary network failure, exceptionally network traffic, strong interference in the area or the recipient has shutdown the phone abnormally (such as removing the battery). Try calling again after a period of time or restarting the phone.
Network is normal and the phone starts searching for network connection automatically
Restore the phone to factory setting and observe.
The online symbol is always shown
Go to Settings > Communications > Data Connection. Change the GPRS connection from "Always connected" to "Connect when needed", and restart the phone.
Slow online speed
Confirm whether the slow online speed is caused by network issues or whether there are too many applications on the device. Clear the internet cache, chat records and messages, remove installed applications, and restore the phone to factory setting.
Phone cannot be charged
1. Check if an original SNOKOR charger is used.
2. If possible, switch off the phone and turn it on again.
3. Unplug the phone from the charger and reconnect it.
4. Test the charge using another compatible device to check if the charger is working.
5. If the phone has completely run out of battery, charge it for at least 20 minutes first or replace the battery (if the device has a removable battery) and see if the other battery can recognise the charger.
6. Note that the phone may not charge in unfavourable ambient temperature (below 0 degree Celsius).
Battery swelling
Check if an original SNOKOR charge is used. Charger from other manufacturers may have different output voltage and current, which may lead to instability, shorten battery life or even damage the battery.
Battery cannot be fully charged
Check if an original SNOKOR charge is used. Using chargers from other manufacturers may lead to a series of problems. In addition, the device may not charge properly in unfavourable ambient temperature. Try charging the phone at a warmer location if the weather is cold or change the battery to see if it is working.
The phone shows that it is fully charged once it is connected to the charger
This is mainly caused by software failure or battery ageing making it impossible to charge. If your device is experiencing this situation, you should contact your local SNOKOR customer service centre immediately to have it checked by a technical personnel.
Battery leakage
If your device is experiencing this situation, you should contact your local SNOKOR customer service centre immediately to have the device and battery checked by a technical personnel.
Overheating
Try to reduce the number of background applications and functions.
In most circumstances, it is normal for the phone to feel a little warm. For example, heating may occur when you are running multiple high performance applications, after prolonged music playback or while the phone is being charged. In addition, the ambient temperature may affect the phone as well.
In order to prevent overheating and to protect itself, your phone may reduce its processing speed, close application and if necessary, restart itself.
What is the firmware and what happens when it is changed
The firmware of the phone is the software, including the phone's operating system, basic calling and messaging functions and other common software, that has been installed on the phone when it is shipped out. Firmware upgrade or update refers to the process where the original firmware of the phone is replaced by a higher version software to add certain functions or rectify any issues of the previous version. The process helps to improve product functions and programs.
My tool cannot detect any new software
Check the firewall setting of your computer and anti-virus installed to see if communication between the tool and the network has been blocked.
Power failure or disconnection during update
For any issues caused by power failure, turn on the computer after power has been restored and open the PC suite to perform repair. (Follow the instructions after opening the program)
