The problem my moto Z had in the past is, battery charge immediately decreased from more than 80% to 0% when I started an app. I thought this problem was related to the battery, but it was not?
I replaced old screen with new one, put the connector and turn on the switch without installing home button, but that does not work, no image is shown on the screen. I removed the battery and re-installed it, check all the connectors & wires, and I could not find any problem. What is the cause of the problem? mother board has been broken?
Thank you very much for your reply. I re-connected the screen three times, but there’s no change, no image is shown on the screen. I followed the instruction, but I may have applied strong force to the screen when I remove it from the mobile? It was really hard to remove the screen because the heater does not heat the mobile to soften the glue. I will replace the screen and see the result.
The screen was connected to the mobile but not glued with adhesive tape yet. Is that the reason why?
I followed the instruction, and I could replace the battery, but no image is shown on the screen. When I push the power switch, the mobile vibrates, so I think battery is Okay. Did I damage the screen when I remove the screen from my mobile?
