● Make sure that whether the object you shoot exceeds the camera's focusing range or not. If yes, the camera cannot focus on that object, which makes the photo look unclear. Just adjust the distance between the phone and object, making they stay in the effective range, that's done.
● Check whether you have set the shooting mode as the Micro mode, if so, the camera is hard to focus on the shooting object as well. Simply change the settings to Normal mode.
● When the color of the object you shoot is very close to the background, it's hard for the camera to focus on it. Try to use some different color background.
● The darkness (the light is dark) and bad shot environment will make the camera hard to focus, too. And it will slow the shutter speed. Turn on the flashlight when taking pictures in such kind of condition. If you don't want to use the flashlight, after you click the shoot button, prevent to move the phone until the picture comes out.

● Please check whether you have turned on the breath light: Enter the phone's Settings - Display - Breath light, tap it to check whether it's on. If not, simply open it.
If the settings is alright but the light doesn't light as well, there are two possibilities: the light is broken, or the phone trash or virus cause this issue.
● So you can use the phone's security app to scan and kill the virus and clean the junk caches, then check whether the breath light works normally.

● Check whether the USB charger is the original one. A non-original power charger has a different input and output power which may cause the battery charge failure.
● Maybe the power charger's metal pin is oxidized if it has been used for a long time. So you use an eraser to clean the pin, and retry it. Or maybe the charging port on the phone be oxidized as well, you can use a cotton swab with some anhydrous alcohol to wipe the port and then wait for a minute until the alcohol is dry. Then charge the phone again.
● Charge the phone for minimum 10 minutes and then boot it. If it fails, continuously press the phone Power button three times and then hold the Power button for 10 seconds to see whether it can be opened.
● Or keep connecting the phone to the power source, press the Power button for 30 seconds to activate the battery, then release the button. Let it be charged for some time and boot it again.
● Charge with another effective USB cable or appropriate power charger to have a try.
● Once all above solutions are invalid, the most possible reason should be the USB port is broken or the battery has something wrong. You can take it to a local phone fixing store to check and repair, or you can contact the after-sales service to send it back to the factory for a repair.
Maybe it's just because the phone runs out the battery. Or there might be some system errors happening, otherwise, it should be a hardware damage issue. You can try following ways:
