Can I connect my XLR mic to my mobile via an XLR -> USB cable via OTG?

I have an XLR mic. I want to connect it to my mobile phone. But even after using all kinds of solutions / cables / connectors my mobile’s audio (TRRS) socket is not detecting the mic.

I was thinking of bypassing the audio socket by going in for a USB based solution using an XLR -> USB cable (

If I use this cable and a OTG connector, will my XLR mic work in Android? The cable has a microcontroller based chipset inside it which converts analog signals to digital (that’s what the manufacturer says).

My USB pc webcam mic works perfectly on my mobile when connected via a OTG connector. So will the above solution also work?

Does the Google monolithic repo contain mobile app code?

Google as we know from this video uses a monolithic repo. It is not discussed exactly what is inside the monolithic repo and what is outside it however. Clearly open source projects such as AOSP and Google Guava exist outside the monolithic repo, but what about mobile apps for Android and iOS such as Gmail and Google Maps?

Lost my Encrypted mobile phone


Yesterday I lost my Samsung A6+. The guy/girl who picked must have already shut it down.

It is encrypted and it had a locking pattern each time I needed to use it.

  • If the guy does a factory reset(the one went turning on the phone), will he be able to do so, and use it as a brand new?

  • The documents I had in the SD Card are cloud safe, so no worries about losing it. However, do you know if the encryption also goes to the SD card level?

I really doubt that even going to the police to alert them I’ve lost it, would do anything useful in order to have a minor chance to retrieve it if it is one day reconnected to the network, so do you think I should do it either way?

Thanks all!

What are the Different Benefits of Mobile Apps Over Websites?

Mobile users spend extra time on mobile apps than websites. Mobile apps are engaging, customized, convenient, particular and simpler to browse.

A mobile app allows customers to set options based on their interest. Apps provide customized content to users relying on their options, searches, and region. websites provide the massive amount of statistics which isn’t personalized. Any kind of personalization can assist growth conversion rate.

Direct Communication via Mobile App Notifications

In-app and push notifications to play a critical role in communicating with customers. In-app messages are received when someone is using an app while push notifications are obtained at any time. Quick notifications are an amazing marketing device that reaches immediately to users and appeals to customer’s attention. Even as for mails, open charges are lesser and those ignore them without opening.

It also offers the chance to gather and analyze behavior and activity more successfully than a website.

Freedom in Designing

Mobile apps assist you to personalize its look, usage and layout whilst websites depend on browsers to carry out primary features. An app is extra flexible and offer functions like swipe, drag, tap, hold and more. This type of functionality offers an effective experience for users.

Increased Conversion Rate

Not like websites, apps might constantly be in a mobile once installed. It enables in presenting a personalized experience, and also can send notifications to the user. This consistent interaction and availability itself increase the chance of conversion.

Apps Works Faster than Websites

A framework that supports mobile apps is more responsive and quicker than websites based on JavaScript codes. Fast loading apps are more convenient than slow loading websites. Mobile app design allow customers to complete duties much quickly.

Increased security

Mobile apps easily integrate with existing security systems to ensure the excessive levels of protection. Within mobile devices, you can properly access, adjust, and proportion data.

Improved Productivity and Reduced Price

Mobile apps make communication simpler and quicker. Applications increase productivity and this could create extra time to generate additional business and revenue. Mobile applications are effective at managing and manipulating complex statistics, producing charts, reports etc. Websites, however, are generally slow and tough to optimize.

Which high speed / high security ECC curves are preferred on mobile devices?

I’m looking for the most common denominator of ECC curves in consumer devices.

This article describes how a particular ECC curve is ideal for Intel based motherboards. Since I’ll be targeting mobile devices (Android, iOS) and also want to leverage the on-device CPU optimizations for signature verification, I’m looking for an ECC curve that is ideal for them too.

Some things I may need to investigate include

  • CPU-specific documentation
  • OS level support
  • Cross platform interoperability of implementation (encodings, compression, etc)


Since a direct answer to my question doesn’t probably exist, what are the most specific resources to figure out which ECC curve to choose for most efficient consumer use?
