My Tab A (SM-P555) blinks and Powers Off when the battery is still at 26%. It charges and operates fine otherwise…. Except for Touch Wizard frequently stopping, and Facebook occasionally stopping.

Hi, It may be that the battery is failing and needs to be replaced. Even rechargeable batteries have a lifespan. Here’s the Ifixit Samsung Galaxy Tab A 9.7 Battery Replacement guide that may help. Replacement batteries are available online. Search for EB-BT550ABA to find suppliers that suit you best.
