 The version of the nrf connect mobile app is not 4.29.xx but 4.26.xx. 
 The dfu generally succeed on our target however sometimes it failed on another target device. 
 When it doesn’t work, I am attaching a video, attached.

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;If you swipe right in the app, you should see the log which may provide some debug information.&lt;/p&gt;
&lt;div class="quote-header"&gt;&amp;nbsp;=&amp;gt; I&amp;#39;ll check to gather the log.&lt;/div&gt;
&lt;div class="quote-header"&gt;&lt;span style="font-family:inherit;"&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class="quote-header"&gt;&lt;span style="font-family:inherit;"&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class="quote-header"&gt;&lt;span style="font-family:inherit;"&gt;Are you only experiencing this problem with a specific version of the app?&lt;/span&gt;&lt;/div&gt;
&lt;div class="quote-header"&gt;&amp;nbsp;&lt;/div&gt;
&lt;div class="quote-header"&gt;&amp;nbsp;=&amp;gt; We were experienced this problem with our specific device regardless of what&amp;#39;s version.&lt;/div&gt;
&lt;div class="quote-header"&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;Another device is working good.&lt;/div&gt;
&lt;div class="quote-header"&gt;&lt;/div&gt;
&lt;p&gt;Is it possible to attach a debugger to the target device and get debug logs? Maybe the bootloader is crashing.&amp;nbsp;&lt;/p&gt;
&lt;div class="quote-header"&gt;&amp;nbsp;=&amp;gt; We&amp;#39;re sorry that we can not attach a debugger because the device was already on production with housing case.&lt;/div&gt;
&lt;div class="quote-footer"&gt;&lt;/div&gt;
&lt;p&gt;How often does this happen?&lt;/p&gt;
&lt;p&gt;&amp;nbsp;=&amp;gt; On a specific device, it happened at the 100% ratio.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;In addition,&lt;/p&gt;
&lt;p&gt;&amp;nbsp;We&amp;#39;ve got that our overseas&amp;#39; customer reported this dfu problem. So, we were trying to find the reason and solution.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Thanks,&lt;/p&gt;
&lt;p&gt;Jaehong Park&lt;/p&gt;
