Hello. I have been using Omni ROM on my GT-n7100 for 2 months and a few days ago my phone started to not react to charging. For example it shows that it is charging, but percentage is not rising. I have tried everything. even reflashing rom to newer (omni-4.4.2-20140510-n7100-NIGHTLY.zip is my current rom) . But it did not help. What should i do?
