Bmax / Unisoc device

Since Bmax is becoming increasingly popular I bought one of their tablets. Full GApps was preinstalled (which I immediately debloated), and as for custom apps I only saw a popup from their firmware updater.

In adb shell, though, I saw the following packages:

• com.guanhong.guanhongpcb
• com.incar.update
• com.sprd.autoslt
• com.sprd.cameracalibration
• com.sprd.cameraipcontrol
• com.sprd.engineermode
• com.sprd.firewall
• com.sprd.ImsConnectionManager
• com.sprd.linkturbo
• com.sprd.logmanager
• com.sprd.omacp
• com.sprd.overlay.sprdnote
• com.sprd.powersavemodelauncher
• com.sprd.providers.photos
• com.sprd.systemupdate
• com.sprd.uasetting
• com.sprd.validationtools
• com.spreadtrum.ims
• com.spreadtrum.proxy.nfwlocation
• com.spreadtrum.sgps
• com.spreadtrum.vce
• com.spreadtrum.vowifi
• com.spreadtrum.vowifi.conf
• com.unisoc.phone
• com.unisoc.storageclearmanager

I'm not sure about com.sprd.* - com.sprd.firewall could be this chinese app: https://github.com/wangjicong/Android-6.0-packages/blob/master/code/apps/CallFireWall/src/com/sprd/firewall/ui/BlackCallsListAddActivity.java

As for com.spreadtrum.* and com.unisoc.*, since the manufacturer is Unisoc, and Spreadtrum is Unisoc's former name, I assume they're some kind of system apps.

com.incar.update -> maybe the firmware updater?

no idea about com.guanhong.guanhongpcb

If anyone has more information about these packages feel free to share :)
