I use a Moto G4 play device and noticed a weird issue lately. Whenever I launched any Music or video apps and tried increasing the volume, I would get the "Unfortunately, system UI has stopped working" error message. I panicked a little thinking that my new smartphone has somehow got corrupt due to some software issue or due to a malware infection. Checking for this error message in Google brought up many posts where other users were also facing the issue. This at least brought me some peace as I was not the only one facing this issue.

I thought that one of the recent apps that I installed might have caused this issue and uninstalled few apps that was installed most recently. However, this didn't resolve the issue and the same error was still displayed while trying to increase the volume. The next step I tried was resetting the app preferences and clearing the cache. To my surprise this resolved the issue. Hooray! I was able to increase the volume without getting that stupid error message anymore.

I tried this in one my friends mobile who was facing the same issue and it worked! I can't give any assurance that this will definitely work for your device. However, if you would like to give it a try, follow these steps:

Note: Resetting the app preferences will reset all permissions to default. You might have to manually provide permissions for required apps to access storage and contacts.

• Go to the device settings app and tap on "Apps".
• Click on the more options button on the top left,
• Now tap on the option "Reset app preferences".
• Once this is done, tap the back button to navigate to the main setting page.
• Tap on "Storage and USB" and then on "Internal storage".
• Scroll down to the "cached data" section and tap on it to clear the cached data.
• Now restart the device and check.

Did this work for you? If not did you try any other steps that helped you resolve the issue? Please feel free to share your resolution in the comments.

I have been watching series like “House of Cards” and “Mr.Robot” recently and the mention of “Deep web” in them caught my attention. I have heard of it earlier and I knew that it was something to do with secret websites, but never researched to know what it exactly was and how to access it. So I quickly googled Deep web, sometimes also referred to as “Dark web” or “Black web”, and what I learned was very interesting.

So, what exactly is it?

Wikipedia defines Deep web/Deep Internet as “The Deep Web, Deep Net, Invisible Web, or Hidden Web are search terms referring to the content on the World Wide Web that is not indexed by standard search engines. ” These websites can be accessed using proxy applications like “Tor” which relay the traffic through various networks to keep your identity anonymous. Since the identity of users in the Deep web is anonymous, anyone can post about anything or sell anything without revealing their identity.

How to access the Deep web?

Just Google or Bing for “Tor” browser and download it for free from their official website. Connect to the “Tor” network using the browser and make sure that you check your IP address after you are connected to the Tor network to make sure that you actual IP is not visible. Once that is done, you can now just perform a search for the “Hidden Wiki” which contains a list websites that you can access in the Deep web.Since the web address of this Wiki is frequently changed, you can perform a quick search from the Tor homepage itself to get to the current updated web address.

What is in it?

Once you are in the Invisible Wiki, cautiously browse through various links provided, particularly any links that offer paid services. If you carelessly enter any of your credentials to make any purchase, that could be used to track you. There are many hackers in the Deep web who can use your information or even sell your information in the web. There are also many websites that show illegal adult content and you have to be very careful to make sure that you don't visit these sites. You might find various websites that offer recreational drugs, hacker services, fake identities and everything you could possibly think of.

Like every other thing, Deep web can be used for both good and bad. As mentioned above, most of the users use it to do what they can't do publicly. On the other hand, if you look at the good side, there are few countries where the government has made certain websites inaccessible to the public. The people residing in these countries can use Deep web to access these websites that are available for the rest of the world. It has been also used by journalists from various countries to keep their identity safe while looking for and sharing information. Many whistle-blowers who wants to share about conspiracies use the dark web.

So what do you think about the Deep web? Do you think it is good or bad? Have you ever accessed it? If yes what weird things did you find? Feel free to share your thoughts in the comment section.
