Hi Juanma,

Can you investigate this here? Maybe its due to sent files are being cached in memory?

Hello Wayne,

We cannot investigate in Dolphin because we don't have this device. We will do some tests in Tarako.

Thanks Juanma.

William, can you help Juanma here? Maybe confirm first if the same problem is seen with Tarako.

Hi, Wayne and Juanma,

Sorry for the unclear information.
This bug was created as a clone of Bug 1005828.
I cannot reproduce this bug on Tarako but I can reproduce it on Dolphin device.
 * Symptom on Tarako device: App becomes very lag but it still can work.
 * Symptom on Dolphin device: After sending many pictures (6~7), LMK is triggered.

I think it might have something wrong on memory management of Dolphin device.
Because I used the same connectA2 (v016h) version to reproduce it.

Thanks.

William - Can you provide any additional updates on this bug?  It seems unusual to me that the app would work on our lowest spec device (128MB RAM/256MB ROM) but not on the Dolphin (256MB RAM/512MB ROM).  Was this a memory allocation issue specific to the Dolphin?

Hi, Michael,

Sorry for the late response. I was on a business trip and will be in office on April 7th.
I would like to request the other engineer to response you.
Sorry for any inconvenience.

@ Test steps:

Due to I have not recieved the "confirm code" during registering connectA2 on my side using CUCC&CMCC SIM Card, I can't verify this bug today. I will try it again tomorrow.
