I have A10 and am facing below problems. Instead only branding please try to resolve issues.
1. Network issue like slow downloading and Uploading on any carrier. Also late downloading from play store. To fix it I clean my wifi connection history.
2. Background apps get killed even music Stops, Internet pages refreshes (everytime I back to the page). It is killing battery, data and multiple tasks.
3. During Call am unable to use any other app. Probably due to killing of background apps. Also I haven't customised battery options for power saving.
4. Kindly give the similar option of color adjustemnt that present in Oreo 8.1 for Amoled displays.
Please respond. Am waiting for your positive and approe response.
