Disassembly Understands quite difficult. Think a few times before disassembling!
Here is a description of the disassembly process + photo from the insideReboot If the tablet freezes during operation and does not respond to the buttons, then you can take a paper clip or needle and press the reset button through the hole.
If the tablet does not load, a hard reset may help. Hard rezet is done from recovery mode (on the switched off device, hold down both volume buttons and press the power button), a full reset will occur and
all user information and files will be deleted . The device will become naked as from a store.
Manufacturing defects . Only one thing was noticed - spontaneous operation of the touch keys. It is treated by contacting the service, or by exchange with the seller. According to rumors, to prevent re-manifestation (and for prevention), you can turn off the vibration feedback.
If there is a root, then the problem
menu button operation can be solved programmatically.
Instructions here .
Charging. If you look closely at the regular charge, then it uses an expanded version of mini USB, not 5 contacts, as usual, but 10. There must be 2 conditions for a quick charge of the tablet.
- The maximum current issued by the charger must be at least 1 ampere
- The mini USB cable through which it is charging must have 10 connectors
Failure to fulfill one of these conditions dramatically increases the charging time or even allows you to only slow down the discharge.
My experience has shown that when using a tablet in a car only as a navigator, without a registrar, a sufficiently powerful charger and an ordinary cord. The tablet does not discharge below 50%, but usually charges up to 100. Dradd went the other way and made a universal device from a USB cable and a standard charger.
Read here. Well, the most radical option is a car inverter.
