When you open the camera app and try to take a photo or video, the camera displays black screen. This has happened to users of Samsung, HTC, Motorola, Sony, Huawei and other mobile phones. It could be a hardware issue as well as software issue. If it is caused by software problem, there is great chance you can get it fixed by yourself.

Step 1. Power off your phone for 10 seconds. Then reboot it and see if the camera still shows black screen.
Step 2. If the battery is removable, open the back cover of the phone and pull out the battery. Battery pull is other kind of restart, which also helps to fix software glitches.
Step 3. If nothing happens after the phone restarts, uninstall third-party apps that might make the phone camera misbehave, including third-party camera apps or the apps you have recently installed before the black screen problem comes up. After clearing the apps, restart the phone again.

Step 4. Go to "Apps" > "All" . Find camera and tap "Clear Cache". The specific steps to clear camera cache may be different on you device.


Step 5. Hard reset. If the camera problem continues, you need to perform hard reset, which will factory reset the phone and wipe out all data. Remember to make a backup before the reset.
If none of the above steps is able to solve your camera problem, your phone camera is probably defective. In some cases, the camera is loose and out of place because of being dropped or something. And some users found it helpful to firmly press on camera lens for several times. But be careful not to crush the lens and power off the phone before you do so.
If unfortunately, you still can take photos because of the black screen, you might need to send the phone to repair store and get the parts replaced.

Flash on Camera Not Working

You turn on the flash when taking a photo in dim light environment, but the flash doesn't work. For some users, the problem happens randomly. The flash may stop working due to the following reasons:
  • Low battery;
  • Software glitches;
  • Use third-party camera or enable certain filters when taking photo;
  • Hardware damage.
Since we could not be sure about the exact reason, try the troubleshooting step by step:
Step 1. Turn on flashlight on your phone and see if the flashlight functions well. If it is not, your phone may experience hardware damage after being dropped or smashed.


Step 2. Make sure that you are using default camera app and disable any filter.
Step 3. Make sure you phone have enough battery left. And check if you have turned on Low Power Mode on the phone. If you have, turn it off.
Step 4. Power off the phone. If it has a removable battery, remove the battery. Then restart the phone and see if the camera flash go back to normal after the restart.
Step 5. Clear cache data. Go to "Settings" > "Apps". Choose Camera and tap "Clear Cache" or "Clear Data". After clearing the data, reboot the phone.
If it is not a hardware issue, many users find the problem solved after the above steps.

SURFACE MOUNT TRANSISTOR IN MOBILE PHONE & THEIR FUNCTION

Surface Mount Transistor in Mobile Phone and Their Function Surface Mount Transistor or SMT Transistor is an SMD electronic component  made up of semiconductor material like silicon or germanium. There are 2 types of Surface Mount Transistors: NPN Type PNP Type Terminals of a Transistor There are three terminals of a surface mount transistor or thru-hole transistor: Ammeter (E) – Flows current on receipt of forward bias. Electrons are emitted in NPN transistors whereas PNP transistors emit ‘ holes ’. Collector (C) – The terminal of the transistor which receives the emitted electrons or holes. Collector always works or reverse bias mode. Base (B) – The layer between ammeter and collector is called base. Base displays the property of showing low resistance in ammeter junction forward bias and high in collector junction reverse bias. Facts about Transistor Indicating Character : Q or V, TR Function : Switching, Amplification, Regulating Voltage.

BLACK HOLE MYSTERY DATING BACK 40 YEARS SOLVED BY "BEST EVER" SIMULATION  A team of astrophysicists from Northwestern University, Oxford University, and the University of Amsterdam, used graphical processing units to crunch large sets of data and simulate how black holes interact with their accretion disks. The first photo of a black hole was captured in APRIL this YEAR PARIS: Scientists on Thursday unveiled the most detailed simulation of a black hole yet, solving a mystery dating back more than four decades over how the star-devouring monsters consume matter Coming fresh on the heels of the first ever photo of one of the giant objects, which are scattered across the Universe, astrophysicists are now several steps closer to understanding how they form and develop. A black hole is born when a large star collapses in on itself. Far from being a "hole", they are instead incredibly dense objects with a gravitational pull so strong that nothing, not even lig
