After not using my tablet for about 6 weeks I struggled to get it to charge. After buying an original samsung charger its all sorted but not the tablet reboots every 15 minutes. Following other suggestions I cleared the cache in asr mode, and have also done a full wipe in asr mode. Now it loads up connects to the wifi and then reboots every 15 minutes or so. Any ideas? TIA ☺

Since i had many tabs that response badly when battery needs to be replaced i would try that first. Otherwise iT can be a heating problem. But my guess is changing the battery Will work.
