What apps compatible of android OS 8.1 for jvc kw-v230bt

One can only install apps that are compatible with the phones OS.

Hi Kim,

Android 4.4 is actually quite an old version of the O.S. It dates back to October 2013. For you to have an idea, the current version of Android is 8.1. It is possible that the application you want to install requires a more recent version of Android than 4.4.

Sadly, most phones that run version 4.4 cannot be upgraded all the way to 8.1 since each new version of Android requires more and more hardware elements each time, such as requiring more memory or a faster processor.

No that will not work.

There may be volume increasing apps or patches that you could try(Modding)

But I strongly suggest you not to try those. Because that will surely destroy the output sound quality.

It depends on the app. If the app has updates, most of the time it will automatically update when in reach of the internet. If you are looking for apps I came across this website:

you can use android apps to make volume rocker as your power button using this application: https://play.google.com/store/apps/details?id=cz.destil.fixbrokenpb&feature=related_apps#?t=W251bGwsMSwxLDEwOSwiY3ouZGVzdGlsLmZpeGJyb2tlbnBiIl0

and there are also other kind of apps that might be helpful for you like listed in this site: http://blog.clove.co.uk/2013/10/07/android-apps-that-can-be-used-to-replace-the-power-button/

You need to download Adobe Flash player from the android market first.

Hi,

It would be helpful to know the Phone model and whether there is any error message.

Regardless, to troubleshoot, please consider performing the following steps:

1. Shutdown your phone and start it up again. Try working with the Camera again.
2. If it is still not working, to validate if it is an issue with the native Camera app, please download Android Market camera apps like "Camera360 Free" or "FxCamera" and try clicking some pictures.

Hope this helps.

-regards,
