Having bought a phone and it seems like everything was OK, but one day the phone sat down and turned off. After charging and turning on, the numbers from the phone book were deleted from 157 pcs. Left 56. Contacts were only on the sim. Both flyme and Google services were not connected. Removing the sim and changing the places in the tray for the sim did not give anything, rebooting the phone with the sim and without it, flashing the flip from 5 to 6, nothing helped. I noticed that when I decided to try to create a new contact, I wrote that Sim is busy. Then nashol the old button phone put in the same sim and all the numbers there. Again, I'm looking for a phone but with an Internet connection and with a normal (not nano) sim, I insert eta "problem" sim into the phone, I create another Google account (because there was already an owner of the device) copy all the numbers from the sim card to google account , After delete the Google account from the phone and pull out the sim. Inserting me into the meizu sim from the App store downloaded Google services, entered into Google under the previously created account and all the numbers in the phone, then registered an account for meizu and copied the contacts and there again, now I think the loss or removal is not so terrible
P.S. There were 2 phones Mase M3s and M2 mini nano-sim were changing and the result is no, the problem is either in the phone or nano-sim. Helped Lenovo with an ordinary SIM card slot.
