Christine_ASUSThank you for your help. My device is out of warranty, it worked for only a little more than 1 year. Repair fee is half of the cellphone price. Battery works well and I don't drop it on the floor. So I am thinking of is it worth repairing...
Thank you for your asking. The repair engineers will run various initial test on your device when they first receive it. Because they have your device by hand, please do trust their diagnosis.
Is the device out of warranty, you may assess if you want to repair the flash memory by considering repair fee, overall device aging status and future performance. E,g. Battery Aging? Have I ever frequently fallen/broken my device? Will the current storage meet your usage behavior in the future? ...etc.
