Sombady know how to solve this problem ? Official site of i-onik is down only here i can try to solve problem. And sorry for my english.

Battery is too low. Hard reset can be done only from inside android settings. I have not find other way to hard reset it. You must desolder the battery from mainboard, charge the battery directly from a power supply, resolder the battery to mainboard, connect the charger to usb and boot to android.
My tablet has a strange effect. When charging and the screen is off it draws about 200-400mA from charger. If the screen is on it draws 0.7-1A. This is too high, because if i unplug the charger the battery falls down very quick. I have not find why this happens.

How to know is my s7 with broken screen is working or not ?

Hello everyone.
I have samsung Galaxy S7 with broken screen, It doesn't show anything. And I need to know If the device's hardware is working and just the screen is crashed, or the device is totally dead. Because I want to buy a new touch screen and replace it.
I got the phone from my firend and he told me that the phone is working and just the screen is broken.
When I plug it on the charger it shows the red light at the top leftة but when I try to to turn the phone on, NO SIGNAL OF WORKING. No welcome tone is heared, No lights...
And when I plug it to my laptop it show "usb not recognized".
I am confused.
