⚠ The battery heats up while charging. ⚠ It may also restart on its own, even when not charging. ⚠ Storage is 32GB. (Since the storage options are only 128GB and 256GB, 32GB is not an option in the specifications. You can use a microSD card (supports up to 128GB) as external storage, but the card is not included.) After purchase, it was used for 4-5 years and then stored in a drawer. Please consider this with the understanding that there may be other problems in addition to the battery heating and restarting issues. There is no outer box or instruction manual. The model details are unknown.
