there are two settings that can be added/changed in build.prop file on Hyundai a7hd tablet, you can copy them and paste directly in your build.prop
this setting is already in build.prop , it decides about how often does the wifi of the tablet make roaming, if it do it less often then it consumes less power. Standard setting on our tablet is 15, I recommend 150 :
this setting IS NOT in build.prop, you have to add it (copy & paste). It has something to do with the buffers of wifi data, I dont know what exactly are those values, but they work for me perfect so I suggest you use them to, just copy &paste this line to your build.prop and reboot:
Believe me, you will not be dissapointed. My browsers now download pages like 10 times faster, google play also download data 10 times faster - it`s great !
