Phone switching off!
I really need help. The last few days my phone as been switching off. For example it just said 87% and then switched off......it kept getting to the samsung screen and cutting off so i plugged it in and it came on saying 17% then after few minutes went up to 45% then i switched it off and on and it went up to 95% i wondered if it was me rooting it and changing the ROM was the cause so i reset it and unrooted it......but its still happening. i can send it off.for repair but i want to see if i csn rectify it 1st.....would it be worth me buying a new battery or is the phone thats faulty regarding the charging? wanted to check before i buy the charger. i just wanted to kno if someone as had same experience.
thanks in advance
