Question

Mobile devices

Hello,
is it possible to remove stickers from the phone? There is a sticker with IMEI and a sticker with EAC, UA, etc. on the back panel.
Will this affect the warranty service?

Answer 1

Will affect. If it will be necessary to hand over under the guarantee, they can cling to this.

Answer 2

Will not affect, remove the sticker and put in the box.
