[AC Question]

why cant i send photos via viber?

Everytime i send photos via viber i always receive the following message: this app is causing your device to run slowly. To improve your device's performance, disable auto open for this app.
My phone is samsung 6.
Thank you!

Do you have any Task manager or Ram booster app installed in your phone?

Do you have Google Photos syncing in the background? I've found that if I have syncing it will try to upload the photo I just took in Viber (or in camera and sharing via Viber) and while it is doing this many other apps have very limited connectivity to the Net. I turned syncing of in desperation and that fixed it, but then I risk losing photos. After sending the Viber pics, turn photo syncing back on. This is in an SGS6 Edge.
