Troubleshooting Common Issues
Here are some specific issues you might encounter with the Celkon UniQ 4G.
1. Fingerprint Sensor Not Working or Unresponsive
Cause: A software glitch, corrupted driver, or a bad system update can cause the fingerprint sensor to stop working, even if the hardware is fine. The option might disappear from settings or fail to recognize any print.
Solution: A full firmware flash is the best way to fix this. It reinstalls the specific firmware for the fingerprint sensor hardware along with all the necessary system drivers, restoring its functionality if the cause was software-related.
2. “Invalid IMEI” or No SIM Card Detected
Cause: This is a common and serious issue on MediaTek devices that occurs when the NVRAM partition, which stores the phone’s unique IMEI numbers, is erased or corrupted, usually by using the “Format All + Download” option in SP Flash Tool.
Solution: Always use the “Download Only” mode. If your IMEI is already lost, flashing this firmware will not restore it. You will need to find your original IMEI (check the box or phone sticker) and use advanced tools like Maui META to write it back to the device.
3. Performance Lag Despite Having 3GB of RAM
Cause: While 3GB of RAM is good, the MediaTek MT6737M is still a budget-class processor. Over time, accumulated cache, background processes from many apps, and general software “bloat” can still lead to sluggishness.
Solution: A clean flash of the stock ROM is the ultimate optimization. It removes all junk files and gives the system a fresh start, restoring the snappy performance the phone had out of the box. Be mindful of how many apps you install afterwards to maintain speed.
Frequently Asked Questions (FAQs)
- Which of the three firmware versions should I use?
- It is always best to flash the latest available version. In this case, that is V05 from June 2017. It will have the most recent bug fixes and improvements from the manufacturer.
- Will this firmware update my Celkon UniQ 4G to Android 8.0 Oreo?
- No. All available firmware versions for this device are based on Android 7.0 Nougat. This package will not upgrade your Android version.
- Why does my 32GB storage show less than that available?
- This is completely normal. The Android operating system itself, along with pre-installed system applications and recovery partitions, takes up a significant amount of space (often 6-8GB or more). The remaining space is what is available to you for your apps and files.
- SP Flash Tool gives me an error. What should I do?
- The most common errors (like BROM errors) are due to incorrect VCOM drivers. Ensure they are installed correctly (disabling driver signature enforcement if necessary). Also, use a good quality USB cable and a reliable USB port, and always connect the phone *after* clicking the “Download” button.
