I handed over the phone for repair, the screen burned out, took it away as subdued, the SIM cards stopped working, the Wi-Fi does not turn on, I can't do anything, call, Internet access, in short, I gave it to the screen, and took the brick!!!
We replaced the battery in the tablet, but the battery turned out to be very low-power, no better than the old one, the charge lasts for 8-9 hours of online work.
