Hi! I dropped my Xperia Z5 on the ground and problems started to arise from there. I have my a phone cover and the height it fell was at least a foot. It started blinking a red light didn't want to turn on. After a while taking out the sim, restarting it with the off button where the sim is,etc. I gave it time to reboot or do whatever and it came on and looked fine. Now it keeps turning off at random times. Do I need to take it to a technician to take out the battery ? Any advice will help! Thank you!
