If there are colored horizontal lines on the screen, that's maybe because of system failure. Firstly, backup the data on your phone, go to Settings - Additional setting / privacy - Backup & reset to factory reset your ROME X. Go to UMI forum to download UMI ROME X phablet's ROM firmware and then flash the phablet if the factory reset doesn't help.
If there are parallel vertical lines on the display, the most probable cause is the flexible flat cable is loose, which needs to be fixed at professional phone repair shop or the factory.
To solve the problem, you can try:
● Enter System setting - Developer option - Display update, choose Close, close Auto brightness, then restart your phone.
● Backup the data on your phone, then go to Settings - Additional setting / privacy - Backup & reset to factory reset your ROME X.
● Download the ROM firmware at UMI forum to flash the ROME X smartphone.
Go to local fixing store or send the product to its seller to repair the phone if above solutions don't help.
First of all, try rebooting your cell phone and check if the cameras work properly. If not, try the followings:
● System reading error makes the cameras not working. Press and hold the power button until options appear on screen, select "Reboot" to restart the phone.
● The phone runs many programs in its background. Just close the hardly used programs to enable the cameras.
● You have rooted the phone. In such situation, just delete the root software or revoke root right.
● There is not enough memory to save pictures. Empty your SD card or change another larger capacity SD card.
● You installed the camera app wrongly or the app has an error during updating, which causes you cannot use the camera. Uninstall the camera app, then try to take a photo again.
If above methods do not help, maybe the phone cameras are damaged, please contact the seller to solve the problem.
First of all, try rebooting your cell phone and check if the front camera works properly. If not, try the followings:
