iPad mini 16GB wifi randomly shuts down after screen replacement
First of all, I am not new to repairing Apple devices, or even the iPad mini in this case. I own a repair shop in the Netherlands. A customer brought in 2 iPad mini's both wifi only versions with cracked glass. I replaced both digitizers with good quality aftermarket one's. One iPad is working fine, without problems. However the other one randomly shuts down. I already opened it again and disconnected the battery for a couple of minutes and reconnected it. After that I left it powered on during the night and there was no problem. It will still on and didn't shutdown during the night. This morning i started to use the iPad again and all the suddenly it reboots again, most of the times it bootes just fine, after very little usage it reboots.
Does any of you have the same experience, and more importantly, is there a fix?
Thanks for reading! I am looking forward to the reply's.
