@grestuccia1 Need more information on this. What is the device you are using? Does this happen all the time on said device?

Also got a similar report from a Xiaomi Redmi Note 3 (Android 5.1.1). Will try to replicate the issue and get back to you.

@boxme Happens on a varied range of devices for me like ONEPLUS, xiaomi, OPPO, Samsung. Issue does not always occur. Usually occurs when the screen has gone off and then activity is resumed after.

jacksongable commented 7 years ago

Are there any new developments on this, or how to fix it? I want to use this library but it keeps crashing my device.
